How to make an airbrush with your own hands - elementary crafts! Ways to make a spray gun with your own hands Homemade paint sprayer.

Are you still brushing? Then we go to you! We are going to tell you how to make a spray gun with your own hands and paint quickly and without smudges. After all, the device is quite simple, and using ingenuity and imagination, you can make the unit no worse than the factory one!

How to make a spray bottle with your own hands from a ballpoint pen?

We are not joking at all - an airbrush can be made from ordinary ballpoint pen within minutes. The mini-pulverizer will work from a glass or plastic bottle of small capacity. You will paint a large amount of work with such an apparatus for too long, but for small crafts or painting small parts, the device justifies itself, moreover, it even has some advantages. So, you will need a square piece of plastic, rubber or styrofoam and of course a ballpoint pen. In principle, any will do, both collapsible and solid, from which only the tip is unscrewed.

First you need to disassemble the handle - remove the paste and unscrew or cut off the end part. In short, you should end up with a hollow tube through which you can blow freely. We warn you in advance that this tool will work from your “traction”, however, below we will also consider automated options, the main thing is to understand the principle! The cone-shaped tip (the one at the bottom of the handle) needs to be cut off a little to get a wider hole. You can experiment with its diameter - scribbled ballpoint pens in every home come across much more often than writing ones, right?

The removed rod also needs to be disassembled and cleaned of the remnants of the paste with alcohol. We do not need a writing ballpoint, you can immediately throw it away. Now let's deal with the "case": it is necessary to cut a corner from a piece of plastic (rubber, polystyrene). In both walls of the corner, you need to carefully drill or pierce holes for the rod and tube. They should hold tight in the holes, if the holes come out a little more, it makes sense to lubricate them with glue.

We approach the most important thing - the rod, which is from the paste, should slightly go into the hole of the tube, only 2-3 millimeters. When you put the rods in the correct position, you will have in your hands a virtually finished DIY paint sprayer. Test it in action - lower the rod into a bottle of paint diluted to a liquid state and blow into the tube. At the junction of the rods, a whirlwind of air is formed, which lifts and sprays the paint. If the paint does not rise, then it is too thick.

How to make a spray gun with your own hands - we complicate the design!

If you have become the proud owner of a compressor, then why not make an airbrush, cheap in cost, convenient and functional. Of course, you can’t paint a car like that, but for many less painstaking jobs, such as painting furniture or walls, it will justify itself. Plus homemade apparatus is that its simple device does not require as much maintenance as a factory one, and you will save a lot of money on solvents.

In addition, the spray gun you made will work even with a weak compressor that produces 150-200 liters of air per minute, while professional devices require more powerful compressors.

You can make it in a maximum of a couple of hours. Of the consumables, you will need three cores from gel pens, of course empty, the pen body itself and half a meter of thin hose. To make a convenient pistol-shaped case, you will need two blocks, seven self-tapping screws to hold the parts together, the most banal cover from plastic bottle from under the soda and three strips of thin sheet metal.

How to make a spray gun with your own hands - step by step diagram

Step 1: Screw on the lid

On the edge of the bar with the back side, we fasten the cap from the plastic bottle with two screws. The screws must be screwed in so that a hole can be drilled between them, exactly in the center of the cover. This is what you will do when it is fixed. For the hole you will need a thin drill, just the diameter of the core of the gel pen

Step 2: A rod with a tip

The rod through which the paint will flow should protrude from the bar with a metal tip by a few millimeters. The tip is needed so that the coloring composition flows evenly. Use the rest of the rods to extend the main one.

Step 3: Air Tube

We attach the body from the handle from the end to the hose and fasten it on the side where the rod comes out with a metal tip. With its cone-shaped end, the body of the pen should be in contact with the tip so that the latter protrudes slightly above the lower edge of the cone hole.

Step 4: Shut off the air

Of course, every time you turn the compressor on and off in order to pause for a second in applying paint, no one will. To do this, it is enough to pinch the hose. And to make it possible to do this with one hand, we will drill two holes in the bar. The hose will enter the hole closest to the tip, and exit the next hole, forming a loop. By attaching a handle neatly near the loop to hold the entire structure, you can pinch the hose with your fingers. Of course, you can come up with a more complicated design by attaching an air supply regulator - this is up to you!

It remains only to screw the paint container to the lid and connect the hose to the compressor so that the work boils! For the operation of such a sprayer, a pressure of one and a half to two atmospheres is sufficient. If we classify the tool, then we got it. This means that the material will be used sparingly, and the quality of painting or varnishing will be on top!

Why do vacuum cleaners need reverse thrust - the solution to the secret!

Many owners of vintage vacuum cleaners of the "Rocket" type, for the most part, do not even imagine why in such units it is possible to switch the engine not only to air intake, but also to blowing. In modern units, you will no longer find such a function, so why was this done in Soviet products? In fact, if by some miracle a box with accessories has been preserved, you may well find among them a ready-made nozzle for an airbrush! If it is lost in years, it will not be difficult to make an airbrush with your own hands from a vacuum cleaner.

For successful operation of the device, one condition must be met - constant pressure. For this, a receiver is used - do not be afraid of this word, it may well be an ordinary soccer ball or car wheel. The pressure reducing valve will help you control the throughput of the unit. The rest of the design repeats the previous version!

Having built a case into which you can screw a tank for paint, setting up a vacuum cleaner and making a receiver, it remains only to hermetically connect all the details. Tightness is the main condition, because only if it is observed will it be possible to achieve constant pressure. So you've got a great one! You can check the work on water-based paint or lime milk on a simple object. For example, try whitewashing the trees!

The desire to quickly and efficiently paint, without spending a lot of effort, pushes you to think about purchasing an airbrush. Its effectiveness is superior to brush and roller. But buying a tool that costs more than other painting tools is justified if it is used frequently or for painting large areas. If you have to paint a small area or a piece of furniture, then you can assemble the spray guns with your own hands. The design is assembled from affordable and cheap components.

Variety of spray guns

In everyday life, devices of 3 types are used:

• pneumatic;
• electric;
• mechanical or manual.

For the home, a pneumatic type tool is recommended. It works by supplying compressed air from the compressor receiver. The second most popular among home craftsmen is electric. At the heart of the work is a turbine supercharger. Poor mechanical performance. Without human impact, the device is not operational (CM and air are pumped into the tank).

To assemble a homemade spray gun, you need to figure out what parts of it pull the KM out of the tank and transfer it to the base. In this case, air supply sources (compressor or turbine) are not considered. The design of the atomizer is being studied.

The air device (pneumatic or electric) consists of:

• with a needle and nozzle on the body;
• top air cap. There is a hole on the side of it (a form is given to the KM cloud);
• the trigger opens the valve (for air movement) together with the tank (where KM is);
• correctors for the size of the torch, paint supply, air (on a pneumatic type tool);
• air pressure regulators are located on the body, and paints and torches are on the air cap of the electric sprayer.

Air flowing through the channels of the atomizer stumbles upon a valve connected to the trigger.

1. The trigger is pressed. The path for movement inside the body is cleared. Air flies out of the air cap.
2. At this point, CM is not sprayed. It is stopped by the cone of the needle. He rests all the way against the wall of the nozzle.

Such actions are typical if the trigger is pressed weakly. If the pressure is strong, then the situation changes:

1. When pressed hard, the trigger moves the needle away from the nozzle. A passage opens for the CM. Air masses pick it up inside the channels and are already rapidly throwing it forward in a torch of small drops.
2. For many mains powered models, the paint container is located at the bottom of the case. In such devices, the dye is pushed out through the tube by the same flow that enters the tank through the 2nd hole (it is open to it). This technology is used if a do-it-yourself paint spray gun is assembled without a compressor (based on a vacuum cleaner).

On industrial models, the air cap is screwed onto the nozzle. When assembling a bullet gun for painting with their own hands, even great craftsmen do not make this part design because of its complexity. A simpler spray mechanism is used. Although it is less productive.

Assembling a mini oral spray device

The simplest paint sprayer, assembled with your own hands, acts under the influence of human breathing. Its effectiveness is the capacity of the user's lungs.

The volume of transferred CM depends on the diameter of the tubes. The sprayer is designed to work with liquid paint. The coverage is not always good. There may be leaks. This is a mini device that is quickly assembled by hand to cover small areas and parts.

The design is assembled from parts:

• helium or ballpoint pen;
• a jar or a bottle is used as a reservoir large sizes;
• foam plastic, can be replaced with a bar of wood measuring 5x2x1 cm;
• sandpaper;
• thermal gun.

Working process:

1. The handle is disassembled into a body (for the passage of the flow) and a rod (for the exit of the KM).
2. The tapered nose of the rod expands to 3 mm in diameter.
3. The ball is pulled out of the spout of the rod. You need to rub it with sandpaper until it deforms and falls out.
4. The ink mass is removed.
5. At an angle of 90 about both tubes are connected at one point. To secure the position, a piece resembling a matchbox is used. The body of the handle occupies a position along the horizon, and the rod (channel for the movement of the KM) vertically. Perhaps the setting of the outlets will be adjusted. Therefore, it is not necessary to immediately firmly fix the tubes. Just use tape.
6. Spraying in progress.

Tip: The dye outlet (on the rod) is placed in the center of the pen body, which acts as an air tube.

The device works on the principle: the CM is pulled out of the container through the tube due to the air that flies over it. A small amount of dye breaks into small particles under the pressure of air masses and flies forward.

Aerosol dispenser

Before making the spray gun, a composition with a low degree of viscosity is selected. KM and air under pressure are driven into one vessel. The work is based on the principle of aerosol capacity. The tool is compact, without a third-party supercharger. im stained small areas. It is not easy to assemble such a device: it is difficult to fill the paint, pumping air pressure is dangerous.

To assemble the sprayer you will need:

• seamless empty aerosol (from paint, an empty air freshener container);
• medical syringe, 20-100 ml;
• a vinyl tube is put on a syringe;
• the pressure is increased by a pump or compressor with a pressure gauge.

The design as such is not assembled. The essence of the work is in filling the KM aerosol, in injecting it with no more than 2.5 atmospheres.

Sequencing:

1. KM is uploading. The atomizer is removed from the aerosol. It remains to stick out the nose.
2. The vinyl tube is mounted on the syringe until it stops. From the end of the syringe nozzle, another 5 mm is added and cut off.
3. CM is pumped into the syringe.
4. The tip of the vinyl tube on the syringe is docked with the spout on the can.
5. A pressure movement is made to open the aerosol valve.
6. CM is pumped into the tank.
7. When the syringe is empty and the paint is completely pumped, the valve is released. The syringe is removed.

If the volume of the syringe is small, then the procedure for pumping the CM is repeated up to 100 ml.

Important: forcing air into an aerosol is a responsible and dangerous stage. The use of a compressor is recommended.

1. Air is pumped through the needle from the syringe. One end is attached to the compressor hose, the other is pressed against the aerosol tube.
2. After pressing the needle, the valve opens.
3. Pressurized up to 3 atmospheres. For a spray can with a seam, the indicator is 2 atmospheres.

Tip: The can may burst during filling with air. In order not to be splashed with paint, it is placed in a bag.

Blow gun as the main working unit of a homemade device

The unit powered by compressed air is more convenient. Although it takes more time and effort to assemble it. The air comes from a hermetically sealed container. The function of the receiver is to perform a bottle or spray can, can be replaced with a canister. The principle of operation resembles the first device. In this device, the rod is replaced by the barrel of the blow gun. The air supply opens and closes the trigger. Large surfaces are covered with such a spray gun.

To make a tool you will need:

Mini receiver - canister, tubeless nipple, tight hose and pump.

• blow gun;
• the helium pen is disassembled into a rod and a cap;
• capacity 0.5 l;
• to seal the container - a lid;
• a block of wood as a basis for mounting all the constituent elements;
• bottle (can be replaced with a canister). It is intended for injection of air masses;
• from an airless chamber - a nipple;
• clamp and hose;
• compressor (less often the pump is activated).

The spray gun is operational if the container with paint is full and air is periodically pumped up. The presence of a compressor will eliminate the need to perform step 5.

How to make a spray gun yourself? This question will be relevant during repair work in the house, and when applying paint to a car. To create such a device, improvised materials are used, so the cost of a spray gun for paint is low, otherwise it will cost you free of charge.

Making a spray gun with your own hands

One of options- to make. Everyone can make such a device, and the advantage of using it can be felt immediately compared to using brushes, rollers or spray cans.

Airbrush from improvised materials

How to create a spray gun from a car chamber

To make an airbrush, you will need:

• car camera (suitable with or without a tire);
• nipple from an old camera;
• repair kit for rubber products;
• a pump with a pressure gauge, which will be used as a supercharger;
• awl.

How to make a spray gun yourself? To do this, follow the simple instructions:

1. It is necessary to inflate the chamber to make sure that there are no punctures or other defects. If air leaks are observed, repair the damage using raw rubber.
2. Using an awl, make a hole in the receiver, the diameter of which should correspond to the additional nipple.
3. The fitting must be glued using a repair kit, then this part is connected to.
4. We unscrew the nipple and check that the air comes out evenly.

It remains to achieve the desired pressure in the receiver by spraying paint on any surface. The value of the indicator can be checked using a manometer. When you press the aerator button, the pressure level should not change abruptly.

Paint sprayer from a vacuum cleaner

To make a paint sprayer with your own hands in a simple way, you need to choose the right nozzle, which Soviet vacuum cleaners used to supply. Such a detail should be put on an ordinary glass jar (1 l).

Making a paint sprayer from a vacuum cleaner

In order for the spray gun for the vacuum cleaner to meet the required parameters, the outlet of the nozzle should be adjusted. After that, we adjust the end of the hose to the place where the air flow enters the atomizer. If the hole diameters do not match, use electrical tape.

Materials and tools for work

To build, you will need the following materials:

• a container made of glass or plastic with a screw-type neck (diameter must be at least 20-25 mm);
• tube made of aluminum or copper (diameter - 4 mm, length - 20 cm);
• bakelite handle, which will be used as a handle.

Also, to simplify the construction of the spray gun on the vacuum cleaner, you can use a drill with a circular nozzle, you will also need a sealant, a clerical knife, etc.

Preparation for work

To make a spray gun with your own hands, you must first prepare a vacuum cleaner. At the beginning of all work, remove the garbage bag so that the load on the unit is minimal. In addition, all filters that are not involved in protecting the motor from dust should be removed. Air flows will be easier to pass through the suction systems of the vacuum cleaner and better generated.

Materials and tools for creating a do-it-yourself spray gun

If the device has only a suction function, and it is not equipped with a mechanism for connecting a corrugated hose, the vacuum cleaner will need to be improved. How to make a spray gun with your own hands? To do this, air should not be sucked into the pipe, but exit it.

This can be done in two ways:

• change the polarity of the motor contacts;
• redirect the turbine blades.

The first method is best suited for older models of vacuum cleaners, because thanks to the special design of the electric motor, the rotation of the shaft can be reversed. To do this, the contacts that are used to supply power must be swapped with each other, so the motor will start spinning in the opposite direction.

Since newer vacuum cleaners have inverter units, when changing contacts, the desired result cannot be achieved.

For more modern vacuum cleaners, an option is suitable in which the position of the turbine blades needs to be changed relative to their rotation. Most often, this part is set at a certain angle, it should be reflected in the other direction so that the air flows are redirected in the opposite direction. Keep in mind that this method is not universal and is not suitable for all models, so it may not be suitable for creating a paint sprayer from a vacuum cleaner with your own hands.

Making a spray gun from a vacuum cleaner

Do-it-yourself airbrush from a vacuum cleaner has the following stages of creation:

Do-it-yourself spray gun for painting cars

1. You need to bend the tube.
2. Fix it using sealant, glue gun, at the bottom of the nozzle designed for the vacuum cleaner hose. At the upper end, a nozzle should be installed, which is made of a brass rod.
3. We cut a hole, its diameter should correspond to the prepared handle. For these purposes, it is recommended to use a copper tube with a diameter of 2 mm and sufficient length to make it convenient to pump out the enamel.
4. We clean the edge of the copper tube to give it the shape of a cone, insert the part into the socket of the plug connector.
5. To make an airbrush yourself, you need to make a bracket with a groove that must match the size of the nest. To create a bracket, it is best to use a steel sheet.
6. Having prepared all the necessary parts, assemble them so that the end of the suction tube is at the level of the nozzle.

In conclusion, we check on any surface how a homemade spray gun functions. To make the vacuum cleaner sprayer work well, adjust the pressure in it by pressing the tube.

When the correct pressure level for applying the paintwork material is selected, attach the tube to the socket using sealant or any quality adhesive. The airbrush from the vacuum cleaner is completely ready for use.

The nuances of using a spray gun from a vacuum cleaner

The use of a homemade spray gun requires a certain skill, therefore, in order to complete the work as quickly as possible and quality, it is worth following some rules.

1. It is recommended to paint with a vacuum cleaner in a circular motion so that the application result is uniform and accurate.
2. Do not stay in one place for a long time to avoid overspending and achieve a uniform shade.
3. To apply the next coat with a homemade paint sprayer, wait until the previous paint is completely dry.

Please note that if you are going to re-equip a vacuum cleaner that is still under warranty, this automatically removes the device from it, and all upgrades may lead to the impossibility of further use for its intended purpose. To create an airbrush at home, it is recommended to use an old unit that has become unsuitable for the intended use.

3 video instructions for making a spray gun: simple and effective!

For those who often deal with such a process as surface painting, indispensable assistant is a device called a spray gun. The product, painted with it, acquires a better and more uniform coating.

Especially helps out when painting a surface of a large area, excluding the appearance of smears and streaks. In this case, it is not necessary to purchase the device in the store. There are several ways to make a do-it-yourself spray gun.

It is about homemade spray guns that will be discussed further.

Benefits of using a spray gun

Starting to make an airbrush with your own hands, we note the main advantages of using an airbrush over manual painting. These include:

• better and more uniform coloring;
• the appearance of foreign objects on the surface, for example, pile or bristles, is excluded;
• speeding up the coloring process.

Directions in which you can use a self-made atomizer:

• for painting furniture products, wooden structures;
• for painting a car and other metal surfaces;
• for whitewashing ceilings and walls with lime.

Types of spray guns

Before you make a spray gun with your own hands, you should familiarize yourself with its types and features. In principle, there are several varieties of them:

• manual paint sprayer;
• pneumatic paint sprayer;
• airless spray gun;
• combined paint sprayer;
• electric sprayer.

Application directions

Each of them is used for specific purposes. Let's give a brief description:

• The best option for beginners is a manual device. It is also good for more experienced craftsmen. Although, it should be noted that the surface will not be perfect, but better than painted with a brush.
• Pneumatic equipment delivers paint by means of compressed air. Painting with such a device is carried out at industrial enterprises when working with both small products and large areas.
• Very convenient to use is a spray gun with an airless system that provides paint spraying. Its essence lies in the fact that in the process of painting, due to the pressure difference, the flow of paint is slowed down, in contrast to a pneumatic sprayer. This provides certain benefits:

increases the economy of the coloring matter;

allows you to speed up the work;

ease of use.

• Combination of pneumatic and airless spray system wide use in the furniture and aviation industries.
• The electric whitewash gun is powered by a special pump that promotes paint supply. This is a practical option for household coloring products.

Instructions for the manufacture of spray mechanisms

We proceed to consider options for making do-it-yourself paint sprayers. With the manifestation of ingenuity and perseverance, you can get a device no worse than the factory one, and without spending too much money on parts. So, a homemade spray gun can be done in several ways.

Paint sprayer from improvised parts

To make a do-it-yourself spray gun from materials that are in almost every home, you can use the following algorithm:

• Any bottle that has a fairly wide mouth can serve as a dish for filling paint.
• Further, in accordance with the dimensions of the neck, a part is cut out of high-density polystyrene foam. For ease of use and to ensure the desired pressure during the operation of a homemade spray gun, the dimensions must be increased by a few millimeters.
• We proceed to the arrangement of holes in the foam part. There should be two. The first is located strictly vertically, the other - horizontally, in such a way that they intersect.

• Next, we take an ordinary helium pen, the core of which we release from the contents and arrange the parts in this way: the rod from the handle is threaded into the vertical hole, and its body is inserted into the horizontal hole.
• At the final stage, we connect the parts, the mini-spray gun is ready for use.

A mini spray gun made in this way can be adjusted. To do this, you just need to shift the parts of the handle in relation to each other. It can be used to apply a rather dense layer of paint to the surface to be painted or to imitate its different texture.

On the video: a method of manufacturing an airbrush.

Using an aerosol can

The next option under consideration, which will solve the problem, is how to make an airbrush with your own hands from a simple aerosol can. The result is a simple manual home sprayer. Prepare all the necessary details in advance:

• • plastic bottle;
  • bicycle wheel chamber;
  • pump for bike;
  • directly an aerosol can from any perfume used.

On the video: a variant of creating an airbrush.

How to make a homemade atomizer of this type will tell you the following instructions:

• We remove the nipple from the bicycle tire. We try to form the base of the nipple with a diameter of at least 3 cm.
• A hole is made in a plastic container and a nipple is fixed on the inside. It plays the role of a pump that will provide air pressure.
• The nebulizer is removed from the aerosol can. To do this, use a hacksaw.

• Using cold welding, we attach the atomizer to the bottle cap. It is necessary to ensure a high degree of tightness of the connection.

Making a spray gun with your own hands using this method will allow you to get an analogue of an airless spray gun. It can be filled with both paint and water-based and lime composition.

Vacuum cleaner application

When whitewashing, painting walls or ceiling surfaces of large sizes, the use of sprayers presented above is problematic. We will try to answer the question of how to make an airbrush at home more powerful. In this case, it is necessary to create a mechanism with automatic air supply.

You can make a sprayer of this type using a vacuum cleaner or a compressor part from a refrigerator. Vacuum cleaners of the old type of production are best suited for these purposes. You can easily attach a hose to them, both at the air outlet and at the inlet. With such a device, feel free to whiten with water-based paint or limestone-based mortar.

Powder formulations will not work.

In the photo: a drawing of an airbrush using a vacuum cleaner.

We provide instructions on how to make a spray gun from a vacuum cleaner:

• • We determine the direction of thrust by changing the position of the terminals on the starter and rotor.
  • We select a plastic or glass container with a fairly wide neck, at least 50 mm. The volume of dishes should be about 2 liters.
  • We equip the cork for the foam container in accordance with the diametrical section of the container neck. The cork should have a small protrusion, into the lower part of which the body from the handle or part of the tube from the dropper is inserted.
  • Two holes are made in the cork by drilling. One of them is intended for the intake of lime, and the second for the supply of compressed air.
  • It is necessary to think about an additional hole, which will ensure the flow of air into the tank, and with a decrease in the amount of lime, it will provide rarefaction of air.
  • Then we make another cork from large foam plastic. Its purpose is to connect the spray gun and the hose for the vacuum cleaner.

On the video: an example of the operation of a homemade spray gun from a vacuum cleaner.

The main nuances of using a sprayer

In order to be able to properly use the sprayer yourself, you need to listen to the main recommendations of specialists:

• When spraying paint or lime mortar, do not linger in one place. This is fraught with the formation of a thicker layer than necessary. It is better to keep the same time periods to ensure an even layer of staining.
• It is necessary to place the rod from which the paint comes strictly perpendicular to the surface to be painted.
• Circular movements with the gun will also allow the paint to be evenly placed on the surface.
• If the paint is applied in several layers, then each subsequent one must be applied after the previous one has completely dried.
• An important role is played by preliminary preparation of the painted surface.

The process of making a spray gun with your own hands is quite time-consuming, which should be approached with all responsibility. A home-made spray gun will significantly save money and get a high-quality painted surface, and, importantly, save on paint solutions. Indeed, when working with a spray gun, material consumption is significantly reduced.

Airbrush

Making a spray gun with your own hands at home

People related to painting work will always have an airbrush available. The tool allows you to paint the object evenly and efficiently, compared with a roller or brush.

This difference is perfectly visible on large areas - there are no smudges and stripes. Specialists select the right product for themselves in stores. When it is not possible to purchase a sprayer, ingenuity comes into play.

You can make a mini spray gun with your own hands.

Homemade atomizer

Those who are faced with the need to make a homemade spray gun only need to realize their desire by following the instructions and using available tools.

In apparatuses that spray paint, you can use vacuum cleaners, compressors from refrigeration units, ballpoint pens, car cameras. Let's try to figure out how to create the necessary tool for the job out of all this.

Purpose and types of spray guns

Depending on the degree of complexity, the type of apparatus can be used for a specific purpose. In addition, the ability to work with a "gun" even for a non-professional is of great importance.

Considering the spray variety, they usually distinguish the following types:

• manual and electric;
• pneumatics and airless systems;
• universal combined tools.

The manual paint spray system is good because even a person who does not have any experience can handle it. The quality, of course, is low. But on the other hand, you can paint a fence or a barn, and at the same time work out.

The electrical kit is also suitable for work at home (for beginners). Thanks to the electric pump, the process of spraying paints and varnishes takes place.

note

Pneumatic systems are used in enterprises where there is a single network of air supply pipes. The network is connected to a single compressor and used for its intended purpose: a press, spray guns, pneumatic hammers.

Unlike pneumatics, the airless system does not use air pressure, but the pressure difference at the outlet of the "gun". The air currents are slowed down and help to coat faster and easier, while saving more consumable material than in the first painting method. Among the shortcomings can be called too thin a layer of coating.

The combined version of how to make a torch at home embodied both of these methods. It is used in aviation, car building and furniture industry.

Airbrush Making Instructions

In almost every home there is improvised material for production. The most primitive option is to use a ballpoint pen. To work, you will need a pen, syringe needles and any small plastic bottle.

Spray bottle collection process It will take a little time and will take place in several stages.

Paste is blown out of the rod and it is thoroughly washed with solvent.

A hole is made in the cork of the bottle similar in diameter to the rod.

A hole is drilled from the end of the cork along the diameter of the handle body. The hole is perpendicular to the previous one.

Insert the rod and body of the handle into the hole and connect with a needle.

The mini spray gun is ready to go. Air is blown out by mouth or enema (rubber bulb). Often this is used by manufacturers of models of aircraft, ships and other toys.

The second easiest will be a spray from an aerosol can. In production will be involved:

• camera from a bicycle or car;
• bicycle pump;
• any plastic bottle;
• any empty deodorant bottle.

The assembly of the device begins with the fact that a nipple is cut off from the camera with a piece of rubber around it with a diameter of at least 3 centimeters. After that, a hole is made in the bottle, into which a nipple is threaded and glued from the inside.

Observing precautionary measures, the upper part with the valve is sawn off from the can with a hacksaw. The valve is connected to the bottle cap by the method cold welding. The diameter of the cylinder and bottle must match. Paint material is poured into the container. Air is pumped through the pump.

A homemade spray gun assembled in this way belongs to the category of airless paint sprayers. Used as a regular deodorant. At relatively low pressure (3 atmospheres) it is used for whitewashing ceilings and painting walls with water-based dyes.

If the house does not have a pump, but everything else is available, try using a rubber enema to apply pressure.

Repair of large rooms will be problematic if you do not know how to make a spray gun at home. Moreover, it is necessary not only to do it, but also to have an automated system. It is best when you have an old vacuum cleaner. Soviet vacuum cleaners do an excellent job with the role of an air blower.

Spray gun assembly instructions based on a vacuum cleaner:

As a container for the dye, a glass or plastic container with a neck with a diameter of 5 centimeters or more is used.

A foam plug with a protrusion is inserted into the neck.

Two tubes are inserted into the cork at right angles. Air is supplied through one, and paint through the other.

Another nozzle is made of foam to align and connect the tube on the lid with the vacuum cleaner hose.

Such a unit is good because, in fact, it is a home-made spray gun for painting cars with your own hands. Moreover, when there is a garage, you can always paint any car part.

Using improvised means and following the instructions, making an airbrush with your own hands at home is not so difficult.

Advantages of a homemade tool

Any home master will say that the units of their own production are not inferior even to factory ones. Indeed, this worthwhile thing solves several problems at once:

• It will help to save on the purchase of a spray gun.
• If necessary, you can always repaint the car.
• Whitewash the ceilings in the house.
• Refurbish furniture with varnish or paint.

One of the biggest advantages of working on the production of a "torch" will be getting rid of the accumulated rubbish in the garage or apartment.

The quality of the coating depends on painting skills and a good spray gun. Homemade design does a great job, she has a whole several advantages:

• Unpretentiousness. Unlike factory, simplicity does not require special attention.
• The paint sprayer of our own production weighs much less. Yes, the size can vary greatly.
• Economical spraying of the coloring matter.
• Compared to the "competitors" (roller, brush), it takes several times less time to work.
• The quality of the coating will be smoother and more uniform.

Almost everything can be painted with a product of your own production. In addition, with its help it will be more convenient to crawl into hard-to-reach places.

Do-it-yourself spray gun from improvised means - it's easy! + Video

Are you still brushing? Then we go to you! We are going to tell you how to make a spray gun with your own hands and paint quickly and without smudges. After all, the device is quite simple, and using ingenuity and imagination, you can make the unit no worse than the factory one!

How to make a spray bottle with your own hands from a ballpoint pen?

We are not joking at all - an airbrush can be made from an ordinary ballpoint pen in a matter of minutes. The mini-pulverizer will work from a glass or plastic bottle of small capacity.

You will paint a large amount of work with such an apparatus for too long, but for small crafts or painting small parts, the device justifies itself, moreover, it even has some advantages. So, you'll need a square piece of plastic, rubber, or styrofoam, and of course, a ballpoint pen.

In principle, any will do, both collapsible and solid, from which only the tip is unscrewed.

First you need to disassemble the handle - remove the paste and unscrew or cut off the end part. In short, you should end up with a hollow tube through which you can blow freely.

We warn you in advance that this tool will work from your “traction”, however, below we will also consider automated options, the main thing is to understand the principle! The cone-shaped tip (the one at the bottom of the handle) needs to be cut off a little to get a wider hole.

You can experiment with its diameter - scribbled ballpoint pens in every home come across much more often than writing ones, right?

The removed rod also needs to be disassembled and cleaned of the remnants of the paste with alcohol. We do not need a writing ballpoint, you can immediately throw it away.

Now let's deal with the "case": it is necessary to cut a corner from a piece of plastic (rubber, polystyrene). In both walls of the corner, you need to carefully drill or pierce holes for the rod and tube.

They should hold tight in the holes, if the holes come out a little more, it makes sense to lubricate them with glue.

We approach the most important thing - the rod, which is from the paste, should slightly go into the hole of the tube, only 2-3 millimeters. When you put the rods in the correct position, you will have in your hands a virtually finished DIY paint sprayer.

Test it in action - lower the rod into a bottle of paint diluted to a liquid state and blow into the tube. At the junction of the rods, a whirlwind of air is formed, which lifts and sprays the paint. If the paint does not rise, then it is too thick.

How to make a spray gun with your own hands - we complicate the design!

If you have become the proud owner of a compressor, then why not make an airbrush, cheap in cost, convenient and functional.

Of course, you can’t paint a car like that, but for many less painstaking jobs, such as painting furniture or walls, it will justify itself.

The advantage of a homemade device is that its simple device does not require as much care as a factory one, and you will save a lot of money on solvents.

You can make it in a maximum of a couple of hours. Of the consumables, you will need three cores from gel pens, of course empty, the pen body itself and half a meter of thin hose.

To make a handy gun-shaped case, you will need two blocks, seven screws to hold the parts together, the most commonplace plastic soda bottle cap and three strips of thin sheet metal.

On the edge of the bar with the back side, we fasten the cap from the plastic bottle with two screws. The screws must be screwed in so that a hole can be drilled between them, exactly in the center of the cover. This is what you will do when it is fixed. For the hole you will need a thin drill, just the diameter of the core of the gel pen

The rod through which the paint will flow should protrude from the bar with a metal tip by a few millimeters. The tip is needed so that the coloring composition flows evenly. Use the rest of the rods to extend the main one.

We attach the body from the handle from the end to the hose and fasten it on the side where the rod comes out with a metal tip. With its cone-shaped end, the body of the pen should be in contact with the tip so that the latter protrudes slightly above the lower edge of the cone hole.

Of course, every time you turn the compressor on and off in order to pause for a second in applying paint, no one will. To do this, it is enough to pinch the hose. And to make it possible to do this with one hand, we will drill two holes in the bar.

The hose will enter the hole closest to the tip, and exit the next hole, forming a loop. By attaching a handle neatly near the loop to hold the entire structure, you can pinch the hose with your fingers.

note

Of course, you can come up with a more complicated design by attaching an air supply regulator - this is up to you!

It remains only to screw the paint container to the lid and connect the hose to the compressor so that the work boils! For the operation of such a sprayer, a pressure of one and a half to two atmospheres is sufficient. If we classify the tool, then we have a low-pressure spray gun. This means that the material will be used sparingly, and the quality of painting or varnishing will be on top!

Why do vacuum cleaners need reverse thrust - the solution to the secret!

Many owners of vintage vacuum cleaners of the "Rocket" type, for the most part, do not even imagine why in such units it is possible to switch the engine not only to air intake, but also to blowing.

In modern units, you will no longer find such a function, so why was this done in Soviet products? In fact, if by some miracle a box with accessories has been preserved, you may well find among them a ready-made nozzle for an airbrush! If it is lost in years, it will not be difficult to make an airbrush with your own hands from a vacuum cleaner.

For successful operation of the device, one condition must be met - constant pressure. For this, a receiver is used - do not be afraid of this word, it may well be an ordinary soccer ball or a car wheel. The pressure reducing valve will help you control the throughput of the unit. The rest of the design repeats the previous version!

Having built a case into which you can screw a tank for paint, setting up a vacuum cleaner and making a receiver, it remains only to hermetically connect all the details.

Tightness is the main condition, because only if it is observed, it will be possible to achieve constant pressure.

So you got a great whitewash spray gun! You can check the work on water-based paint or lime milk on a simple object. For example, try whitewashing the trees!

Making a spray gun with your own hands

For uniform, accurate and high-quality painting of any type of surface, it is more advisable to use a device such as an airbrush or, as it is also popularly called, a spray gun.

The use of such a device allows you to create a high-quality paintwork on an area of ​​various sizes, while almost completely eliminating the possibility of creating stains, smudges and unpainted areas.

However, the purchase of an airbrush in a distribution network is a costly business, and not always justified. It is more reliable and much cheaper to make a homemade spray gun with your own hands.

Description and scope

There are the following types of spray guns:

• Manual.
• Pneumatic.
• Airless.
• Combined.
• Electric.

Depending on the type and principle of operation, spray guns are used in the following cases:

Optimal application manual equipment considered for people who do not have sufficient experience in carrying out painting work. Due to the simplicity of the equipment, the quality of the coating layer is imperfect.

When using a pneumatic type tool, it is meant to apply a layer of paints and varnishes under the influence of compressed air. This method is used in various industries in large enterprises. With the help of pneumatic type spray guns, both small-sized parts and large areas are painted.

The airless paint application system involves the use of the pressure difference when the paint exits the spray nozzle of the spray gun. The action of air at the same time slows down the rate of spraying of the substance, and not, as is the case with pneumatic equipment, builds up pressure. This principle of operation has a number of advantages: high speed of work, economy of paint consumption, ease of coating large areas. The only negative is the thin coating layer, which can be easily damaged by physical impact.

The combined painting method combines both methods, which makes it possible to use it in the aviation industry and furniture production.

Spray gun system electric type involves the use of a pump, due to which the spraying process is carried out coloring composition. The use of such a system is most widespread.

Among the main functional elements of the spray can be identified:

• Housing - has two valves that suck in air and pump the coloring matter. The head can rotate freely to be able to easily change the direction of the paint.
• The pressure part is responsible for creating pressure during the transfer of the coloring composition. Made in the form of a sleeve made of different material(rubber, polyurethane).
• The suction part is equipped with a filtration system that prevents the atomizer from clogging during operation.
• Fishing rod - consists of two parts, designed to adjust the length of the spray gun itself.
• The pump is located inside the body part. The principle of operation is based on the interaction between the pistons of the mechanism.
• Tank for coloring material.
• Lid for tight closure of the tank.

Advantages and disadvantages

Among the main advantages of using a spray gun, it can be noted:

• Low cost compared to pneumatic surface painting equipment.
• The simplicity of the design allows anyone to use the tool, even without experience in painting.
• Uniform and fast application of the composition for painting on the surface of any type and size.
• Easy repair in the event of minor breakdowns.

However, along with undeniable advantages manual spray guns, there are some disadvantages:

• The need to constantly maintain air pressure, which is not very convenient in the implementation of the workflow, since pressure surges significantly impair the uniformity of the paint jet supply to the surface. This problem is especially relevant for beginners inexperienced craftsmen.
• The need to use water-based coloring materials.
• The formation of the so-called fog, when small particles of the paint coating settle not only on the surface of the painted part, but are also able to settle on neighboring objects. Therefore, in preparation for painting the surface, adjacent parts of the product are covered with a protective film of polyethylene.

For whitewashing

With the help of an airbrush, you can perform not only surface painting, but also whitewashing the walls.

For the manufacture of such a device, you will need a glass or plastic reservoir for liquid with a diameter of at least 3 cm.

In addition, you need to prepare an aluminum or copper tube 200 mm long and 4 cm in diameter. The tube must be bent and connected to a vacuum cleaner hose or a spray bottle.

The tip will be a brass nozzle, which can be purchased from a distribution network or made independently. Various options constructive manufacture of nozzles can create the possibility of using the spray gun in various modes of painting or whitewashing.

Then you need to prepare a socket from the plug connector and insert a tube with a diameter of 2 mm into it. After the manufacture of the metal bracket, we connect one end of it with the conical part of the mechanism.

Next, we connect all the elements of the product and adjust the tube that will suck in air. We fix this tube, using a soldering device or glue, strictly along the axis. Additionally, install the connecting nut.

Checking the performance of the device is carried out by test painting, while you need to make sure that the spray is of high quality and uniform.

For water based paint

With a small amount of painting, you can make a fully functional device from an ordinary ballpoint pen. Such a spray gun will work perfectly with a coloring agent with a volume of up to one liter. To make such a mini-spray gun, you will need an ordinary ballpoint pen and a piece of rubber, polystyrene or rectangular plastic.

Remove the mini tip at the bottom of the pen and remove the ink. If it is impossible to remove the rod, you can carefully cut it so that air can freely pass through the cavity of the tube.

We experimentally select the diameter of the hole obtained by cutting off the cone-shaped part until you achieve the required quality of staining.

To remove the paste from the rod, you can use an alcohol solution. Next, using a drill, we make holes in a rectangular blank. The diameter of the hole must match the diameter of the tube with the rod.

The rod goes deep into the tube by no more than 3 mm. When connecting the parts, do not forget to lubricate them with adhesive.

Remember that it is the high-quality connection of the parts to each other that is the result of the high-quality work of the paint sprayer.

Having immersed the entire part in a container with a dye, we blow into the spray tube. In this case, under the action of an air vortex, the paint will be pushed out of the sprayer. If this happens with great effort, then it is necessary to additionally make the composition of the coloring matter more liquid with the help of special paint solvents.

From an old refrigerator

This option for manufacturing a painting device is considered the longest and most time-consuming, although patience will not go unnoticed and as a result the device will turn out to be multifunctional and reliable. To make an airbrush, you will need some spare parts from an old refrigerator:

• Compressor unit.
• Container for dye.
• Clamps (diameter 20 mm).
• Connecting hoses (one 40 cm long, two 10 cm long).
• Automobile filter.
• Steel wire.
• Wooden board and a set of screws.

After preparing the components, you can begin to assemble the spray gun:

• Any fire extinguisher or metal canister with a tight-fitting lid will work fine as a receiver.
• The first step is to position and secure the compressor on a base of wooden boards.
• A standard refrigeration compressor has three copper tubes, one of which is brazed.
• Connect the compressor to the power supply and experimentally determine the air inlet and outlet in the device. Then we connect the connecting hoses, and tightly fix the connection points with clamps.
• A tube with a sealed end is used to supply lubricant to the inside of the compressor. If the unit functions without problems, then it is better not to take any action with it.
• Then, in the receiver housing, you need to drill two holes in which the hoses are installed. The long pipe is connected to the compressor inlet, and the short one, respectively, to its outlet.
• It is desirable, in order to be able to control the pressure in the receiver, to fix a pressure gauge on its body.
• The receiver must be fixed on a base next to the compressor.
• Make the appropriate connection of the hoses, and to clean the incoming air, we put a filter element at the inlet.
• The final step will be the installation of a spray gun of the coloring composition.

For better movement of the entire unit, given its large dimensions, it is possible to equip the structure with wheels.

Device selection and security measures

In the manufacture of a spray gun for painting cars important condition quality work is considered right choice compressor.

It will be able to provide the necessary air pressure to spray the paint.

Many models of old vacuum cleaners do an excellent job with this task, which have the function of blowing air, along with the standard function of blowing it. Modern models Vacuum cleaners do not have this mode of operation.

To ensure a constant supply of air and thus the possibility of high-quality painting of the surface, it is necessary to include a receiver in the design of the spray gun. To accomplish this task, you can use an automobile rubber tire or a soccer ball. It is this simple device that creates the versatility of the entire staining system.

When painting any surface using an airbrush, it is necessary to follow the basic safety rules: use protective clothing, paint shoes, a respirator or mask to protect the respiratory tract of the human body and eyes from small particles of the coloring matter.

Before starting the painting process, be sure to check the paint for viscosity. Too thick paint will spray poorly and constantly clog the spray gun nozzle. Fulfillment of this condition will help to avoid many breakdowns of the equipment.

For successful painting of any surface, it is recommended to use useful tips from professionals:

• When spraying the coloring matter, you do not need to linger in one place for a long time so that the layer does not turn out to be too thick.
• It is necessary to direct the jet of paint strictly perpendicular to the surface of the part to be painted, otherwise a large consumption of paint is possible.
• To create an even layer, it is desirable to paint in a circular motion.
• Only after the previous layer of paint has completely dried, a new layer should be applied.
• Before starting the painting process, it is necessary to make a quality surface preparation.
• The paint that is used in the work should not have any lumps and foreign inclusions.

Of course, a lot of time and effort is spent on making an airbrush with your own hands, but then further work on painting any surfaces and various types of dyes will be much simplified and performed with better quality.

The airbrush is a universal tool for applying paint, which allows you to paint any object as quickly and efficiently as possible. However, buying an airbrush is an expensive process that is not always justified. It is much cheaper to make a spray gun yourself. We will learn more about how to build spray guns for various purposes.

Manual spray gun: features and benefits of the tool

A manual spray gun has a simpler structure than a pneumatic one. The principle of its operation is to expel the coloring composition with air. Among the main components of the spray gun are:

• body part - it is distinguished by the presence of two valves that pump air and suck in paint, this part freely rotates and changes the direction of paint supply;
• the pressure part in the form of a sleeve - is responsible for the pressure when applying paint;
• suction part - has a filtration system that prevents clogging of the nozzle;
• fishing rod - has two parts, regulates the length of the tool itself;
• pump - located in the inner part of the housing, it works due to the interaction between the pistons;
• tank for paint;
• lid that closes the jar.

Among the advantages of using a manual spray gun for paint, we note:

• affordable cost - this tool costs less than a manual pneumatic spray gun;
• ease of use - even a person with no experience in painting can handle a manual spray gun;
• fast, uniform application of the coloring composition to the wall;
• The simple design of the manual lime spray gun allows you to quickly repair it in case of breakdowns.

However, the manual spray gun also has certain disadvantages:

• the manual process of work implies constant pumping of air, which is not very convenient during the work process, with pressure drops and surges, the jet turns out to be uneven, especially important for beginners;
• the possibility of using only water-based coloring compositions, only water-based paints or solutions for whitewashing are placed inside the spray gun, however, there is a wide variety of coloring compositions that are also used for coloring, they are not used in the manual version of the paint cult;
• in the process of work, the so-called fog is formed, small particles of paint fall not only on the place of staining, but also settle on other objects, in order to avoid this, all objects located near the place of staining are covered with a film of polyethylene.

Spray guns pneumatic, combined airless - their features

Depending on the technology of spraying the coloring composition, spray guns are divided into three categories. The airless option involves pushing out the coloring composition with the help of its own pressure, which is created inside the mechanism.

In this case, the paint is split into small droplets covering the object. Among the advantages of this device, first of all, the absence of fog during the work process is noted. Also note the lack of the ability to adjust the size of the droplets.

To obtain high quality staining, it is necessary to use expensive equipment.

The pneumatic method of spraying paint involves the effect of air on the coloring composition as it exits the nozzle. Air currents under high pressure push the paint, spraying it. At the same time, the paint is split into small elements, forming a cloud.

Most of the paint settles on the object being painted, but small particles also end up on foreign objects. This option equipment is budget-friendly, but at the same time has high performance in the workflow.

In this case, the paint consumption is quite large, so the equipment is rarely used in everyday life, but is more suitable for industrial painting.

Combined devices are often used, the principle of their operation is to move the paint through the mechanism without contact with air, however, at the outlet of the device, they are affected by a pneumatic element that pushes the paint with great force. Thus, it is possible to keep workplace in cleanliness, there is no foggy cloud, a significant savings in the coloring composition is achieved.

Do-it-yourself hand-held spray gun for water-based paint

If the amount of work is small, then make an airbrush from a pen. Such a device will work with a volume of paint up to one liter. In the process of work, you will need to have:

• ordinary ballpoint pen;
• a piece of rubber, plastic or foam - a rectangular shape.

At the bottom of the handle, you need to remove the tip. Remove the paste from the empty tube. If you can't remove the rod, then cut it off. The air flow should freely pass through the cavity of the tube without delay.

The tapered part of the handle also needs to be cut off, so you can get a good hole. Choose the diameter by trial and error, using a variety of pens, until the result of dyeing suits you.

To clean the rod from the paste, use alcohol, rinse it with it. Next, proceed to the construction of the body part of the spray gun. For these purposes, previously selected material is required.

Using a drill, drill a hole in the wall of the rectangle, the diameter of the hole should be such that a tube with a rod passes through it. For a tighter fixation of all parts, pre-spread them with glue, and then insert into a rectangle.

The rod goes into the inside of the handle by three millimeters no more. The correct fixation of all parts among themselves is the result of the high-quality work of the mechanism.

Install the rod part in the reservoir containing the paint, fill it with compounds and blow into the paint spray tube. At the place where the parts are fixed, an air vortex will form, pushing out the paint of their tool. If the paint does not rise along the spray gun, then it is quite viscous, you need to take care of its additional dissolution.

Hand-held electric spray gun - we build it ourselves

If you have a special compressor unit, you have the opportunity self-manufacturing electric spray gun. It is highly functional and easy to use.

Of course, with the help of such an airbrush it will not be possible to paint a car with high quality, however, it is suitable for applying paint to walls, evenly distributing it over the surface. This airbrush does not need additional care, it is easy to fold and is unpretentious in operation.

For the manufacture of a manual spray gun, you will need:

• several cores from gel pens;
• handle body;
• thin hose, about 25-30 cm long;
• several bars;
• self-tapping screws, with which the parts are fixed to each other;
• plastic bottle cap;
• several metal strips, 2 mm thick.

In order to independently build a spray gun, follow these steps:

1. Install the plastic cover on one bar, fix it with self-tapping screws. Install the fasteners so that a small hole is drilled in the center of the cover. After fixing the cover, use a drill to create a hole. Please note that the diameter of the hole must match the diameter of the rod from the handle used.

2. Install the rod inside the hole, the metal tip should protrude a few millimeters out of it. Do not throw away the steel tip, as in the first case, the paint will flow through it more evenly.

3. Next, the rod is built up with the help of subsequent rods. After that, connect the body part of the handle to the hose. Fix it in that position, at the exit of the steel tip from the rectangular area. The body of the pen is in contact with the tip so as to provide a slight protrusion above the edge surface.

4. Create an element to block the air flow. Thus, it is possible to improve the comfort of using the spray gun. No need to run to the compressor every time, if necessary, to stop the painting process. To do this, it is necessary to ensure the clamping of the hose and the air supply. To do this, build a few holes on the bar.

One approaches the tip, and the second further. The hose enters through one hole and exits the bar through the second. Thus, it is possible to create a loop. At the same time, it turns out to automate the process of stopping the air supply from the compressor. Having installed a handle next to the hose, it is possible to pinch the hose with your fingers.

This method is easier to perform.

After making the atomizer, connect it to a compressor, for example, from an old refrigerator or vacuum cleaner. The pressure in it will be about two atmospheres. With the help of this spray gun, it is possible to paint walls or the necessary furniture without any problems.

Do-it-yourself manual spray gun for whitewashing

We offer another option for manufacturing a universal mechanism, with which you can perform not only painting, but also whitewashing the walls. Using this method of manufacturing the spray gun, it is possible to improve the versatility of the design.

First of all, for work, you will need a plastic or glass liquid reservoir, the diameter of which is at least 3 cm. In addition, you need to prepare a tube of copper or aluminum, 4 cm in diameter, 200 mm long.

The tube must be bent and connected to a spray bottle or hose from a vacuum cleaner.

A brass nozzle, made independently or purchased, will act as a tip. It is possible to manufacture several nozzle options, so the spray gun will have several modes of operation.

note

Next, you need to prepare the socket from the plug connector and install a tube inside it, the diameter of which is two millimeters. Build a metal bracket, connect one end of the tube to the conical part of the mechanism.

Connect all the previously prepared elements of the manual whitewash spray gun, set up the tube that sucks in air currents. Make sure it is in the same position as the axle.

Fix the tube to the socket with glue or with a soldering device. In addition, install a nut on the connection. Check the functionality of the device.

Spraying should be uniform and of high quality.

Features of choosing a compressor and repairing a manual spray gun

For the manufacture of a high-quality spray gun, it is necessary to choose the right compressor that provides a certain pressure for spraying paint. Older models of vacuum cleaners have the function of not only blowing, but also blowing air. The compressor from them will perfectly cope with the functional load of the spray gun.

To achieve high-quality coloring and constant air supply, it is necessary to use a receiver. For this purpose, we recommend using a soccer ball or a rubber car tire.

It is the receiver, with a pressure reducing valve, that regulates the air supply to the spray gun. All parts must be tightly connected to each other. Having achieved this condition, it is possible to obtain a high-quality supply of paint from the mechanism.

Such an airbrush allows you to paint walls, whitewash walls and even trees.

For the manufacture of an airbrush, a minimum of cost and time will be required, but its use in household matters is quite high. However, when performing staining, one should not forget about safety rules. For work, use overalls, a mask and a respirator, as small particles of paint can get into the eyes and respiratory tract.

Before starting work, check the paint for viscosity, too viscous composition will not be sprayed, clogging the spray gun. Adjust the nozzle on the gun to the size of the colorant jet. For these purposes, use a paper sheet.

The interval between the spray gun and the surface to be painted is selected independently in the process of work. Drive the gun from the bottom up and vice versa, overlap the layers with each other.

In order to achieve evenness and uniformity, at the moment when you drive the gun over the object, press it, when the spray gun stops, stop the paint supply.

In order to avoid repair of the spray gun, it is necessary to adhere to certain rules for its operation. First of all, use only water-based paints or lime. After work, wash the tool thoroughly, pay special attention to the nozzle. Otherwise, there is an uneven distribution of paint or even clogging of the nozzle.

To wash off paints of different composition, use water or other solvents in the form of gasoline. Pay attention to the filter of the device - it must also be thoroughly washed. The paint used in the work should not contain lumps and foreign inclusions.

In general, before starting work, check all parts for the absence of paint on their surface. If it does exist, use special solvents to remove dried paint from the mechanism.

Only after that it is possible to assemble all the details into a single mechanism and start working with the device.

How to create a spray gun with your own hands: advantages, creation options, technology

Home craftsmen quite often face the need to paint various surfaces, and it is very important to ensure high-quality, accurate and uniform application of the painting material. This problem can be solved with the help of such a device as a spray gun, better known as an airbrush.

Using this device, the owner has the opportunity to create a durable paintwork on surfaces of any size that will not sadden the owner with streaks, streaks or unpainted areas. In some cases, if the home master has sufficient skills, then he can make a spray gun with his own hands.

Advantages of a homemade spray gun

A device such as a spray gun, has many advantages, which in fully appear when painting various surfaces:

• the possibility of creating a uniform coating of paintwork material;
• the absence of pieces of roller pile or bristles on the treated surface when working with a brush;
• the use of a spray gun allows you to complete painting work much earlier than using traditional tools;
• the paint consumption rate when using a spray gun is quite small;
• light weight and compact size;
• ease of use.

Most often with a spray gun the following tasks are solved:

• surface treatment of furniture, fences and other structures made of wood;
• painting surfaces with a metal base, including car structures;
• creation of dense structures made under plaster and other decorative surfaces.

It seems that few people know that in some cases, using a factory-made spray gun, you can create a lower quality coating than when using a homemade spray gun for work. At the same time, it must be remembered that the skills of the person who will be staining play a decisive role in achieving the result.

How to build a spray gun?

Deciding to independently make a device designed for painting various surfaces, you should prepare the necessary materials.

Under the tank, which will contain the paintwork material, you can adapt a bottle with a wide mouth.

Next, you need high density foam. An element will need to be cut out of it, and one of its edges should have the same diameter as the paint reservoir. Here it is very important to ensure its tight entry into the container. Given that the foam has a porous structure and tends to shrink, it is desirable to expand the lower edge of the workpiece by several millimeters.

Next, a hole must be created in the foam blank. Moreover, it should be done precisely by drilling, and not by piercing or cutting. If you neglect this recommendation, then there is a high probability that the workpiece will be damaged. One hole should be through, a rod from a regular ballpoint pen will be inserted there. Another hole is made horizontally, while the body is placed there from the handle;

At the final stage, you just need to connect two elements together, after which the spray gun can be used.

In order to adjust the paint spray flow, you need to move ballpoint pen elements relative to each other. With the help of such a device, you can achieve a dense layer when applying a paintwork material or create a coating that resembles different textures.

In order for a self-made spray gun to be able to properly perform its functions for a long time, it is recommended to use metal parts instead of elements taken from a fountain pen. When selecting a tank in which the paint will be stored, you should focus on the amount of planned painting work.

Improving a homemade spray gun

If the owner has set himself the task of providing a thinner coating, then this will have slightly modify the device. You need to take a foam blank and drill another hole in it, which should go from top to bottom.

It should have the same direction as the stem of a ballpoint pen, while having the same diameter. By performing a similar operation, you can achieve a significant increase in pressure in the tank where the dye is stored.

Due to this, when performing painting work, the jet will be stronger.

You can also add an additional hole to the body of the handle by placing in it one more rod. Thanks to this solution, it is possible to provide a thinner layer of paint material. This will allow the application different kinds dyes that differ in consistency.

To ensure the longest possible service life of the spray gun created by your own hands, you need to remember the following points:

• If one of the elements of the spray gun is made of foam, then in this case only water-based dyes can be used for the device. To work with paints containing various solvents, this device is not suitable for the reason that this will weaken the material, as a result, the spray gun will be unusable;
• If necessary, you can expand the scope of tasks for which the spray gun will be suitable. This can be realized by using rubber instead of foam. This material perfectly tolerates interaction with chemically active components that are present in the composition of paints and varnishes;
• At the same time, when deciding on the implementation of various improvements, it must be remembered that such a version of the spray gun will not be able to maintain its performance for a long time.

Spray gun for a wide range of applications

If you are interested in making a do-it-yourself spray gun that can solve a wider range of tasks, then you will need to prepare a plastic or glass tank with a neck, reaching a diameter of 20 mm. Having found a suitable container for paint, then you have to perform the following operations:

First you need an aluminum or copper tube with a diameter of 5 mm, which must be bent. We take a vacuum cleaner that pumps air and connect its hole at the lower end of the tube.

At its other end, it is necessary to fix the brass nozzle. If the element used has a large width, it is necessary, focusing on the profile of the tube, to cut a groove. After that, you need to fasten the elements of the handle together using screws. Then the finished parts should be sanded.

Next, you need to take a suction tube with a diameter of 2 mm. It must be placed in a brass socket. Please note that the tube must be the same length as the selected paint reservoir.

After performing the operation of the previous stage, it is necessary to make a metal oval bracket, which should have a hole for the socket. Next, the upper part of the tube must be bent, giving the shape of a cone, and cleaned.

Then it's time to assemble the spray gun. To do this, move the suction tube until the upper end is on the axis of the nozzle.

After that, the finished mechanism should be checked for operability and, if necessary, adjusted properly. Manipulations consist in choosing the height of the end of the tube. The optimal level will be the one at which the created layer of paintwork material will have a minimum uniform thickness.

When the mechanism is set, the suction tube must be fixed to required level what the spike is used for. It is attached to a socket mounted on the lid of the paint reservoir.

After performing the described steps, it remains to tighten all the parts of the spray gun. Now it can be used for coloring.

It will provide a self-made spray gun with a wider range of tasks that it could solve, if you use nozzles with different diameters.

Airbrush from parts of an old refrigerator

When deciding on a similar option for creating an airbrush with your own hands, you should remember that you will have to spend a lot of time and effort on this work. At the same time, this will not be in vain, since the finished spray gun can demonstrate high reliability and versatility.

materials

If you finally decide to use an old refrigerator to make a homemade airbrush based on it, the first thing you should take care of about the presence of the necessary elements:

• compressor;
• a paint tank of suitable dimensions;
• a set of hoses, including one 40 cm long, two others 10 cm each;
• clamps reaching a diameter of 20 mm;
• car filter;
• metal wire;
• fragment wooden board and screws.

Work technology

Having resolved the issue with spare parts, it is necessary to perform a number of preparatory operations:

• A fire extinguisher or an available canister or other metal container that can be hermetically sealed can handle the role of the receiver;
• One of the first steps should be to securely fix the compressor on a wooden surface;
• The compressor, which is equipped with a refrigerator, includes 3 copper tubes, among which one has soldered ends;
• To understand which pipe should be used to connect the compressor to the household network, you should experimentally find out which hole the air comes from. Based on this, it can be determined that he will act as the main output. In turn, a free open pipe will play the role of an entrance. Each end needs connect hoses of suitable diameter, while the joints should be securely fastened with clamps;
• The purpose of the sealed tube in the refrigerator is to lubricate the compressor. Therefore, in the absence of a malfunction in the operation of the motor, no action should be taken in relation to it;
• The design of the receiver must be modified by making two holes in it. Two hoses will be exposed there: the pipe of the greatest length will be used to connect to the compressor inlet, a pipe segment with a shorter length must be connected to the outlet;
• To have an idea of ​​​​the force of the injected pressure, you should additionally install a pressure gauge;
• To place the receiver, a place is selected on the basis of the compressor;
• One hose is used to connect two devices at once, while the second pipe must be connected to the filter. The purpose of the latter will be to remove pollution from the air;
• The last operation of the work is to connect the paint sprayer.

In view of the large dimensions of the self-made spray gun, it will be useful screw the wheels to the wooden base. This solution provides greater convenience when using the spray gun.

Conclusion

To obtain a better result when performing painting work, it is most effective to use such a device as an airbrush. If necessary, each owner can make this device with their own hands. Given the complexity of the design of the spray gun, there should not be any problems with its creation.

To make it, you can use available materials that are available in every home.

In order to avoid mistakes and obtain the desired result when painting, it is necessary to follow the manufacturing technology of the spray gun exactly.

By acting in this way, it is possible, at minimal cost, both in terms of finances and time, to produce an airbrush that will surpass even a factory-made device in terms of quality of work.
