Sandblast do it yourself at home. How to make a sandblasting machine with your own hands. What is called sandblasting

It is rather tempting to have a sandblasting device, which can not only spend the stripping of planes and niches from rust and dirt, but also to perform thinner work. For example, engraving on glass. Ready sandblasting can cost about $ 150-200, and if it is used from time to time and not professional purposes, then it is not necessary to give a rather large amount. You can do everything yourself.

Principle of operation and sample of sandblasting

First of all, it is worth deciding for what purposes the device is going. If we need thin work with small details, then the requirements for the apparatus will be alone, and if we plan to stripping the bottom of the car, and not one, and several, it will be a more productive design. But be that as it may, the following elements are needed for any machine:

air blower;
sand reservoir;
air mains;
highway for sand;
straightening elements;
pistol for spraying.

This is generally in general. And the principle of sandblasting is quite simple and understandable. A river crystal sand is loaded into the tank with a closed volume, such as in the hourglass, two contours are connected to the tank - injection and working. The injection circuit is connected from below and has a protective check valve (ideally). The working circuit is connected to the tank on one side, on the other hand it is connected to the spray gun.

Opening the valve on the gun, we bleed the pressure, and along with the air the sand jet is fed, which clears the desired surface or part. All things. This is classic sandblasting. As an example, consider the simplest version of the device, which can handle the spark plugs, for example.

Simple sandblasting machine

The scheme of the simplest sandblasting machine is presented in this section and the device makes it clear the principle of operation of the system. It looks like this. The same river sand is poured into the container. In the bottom of the tank, a hole is drilled through which air from the compressor or the hand pump is supplied. From above, the container is closed with a dense cover, in which a hole under the spark plug and a hole for airbagging and the sand collection is drilled.

The hose is inserted into the hole, which is installed in the second end in the sand tank. If you do everything neatly, then the sand hose can be sealed with a bag, then the process of cleaning the candles will take place at all silently and not raising dust. After the candle is polished, it is blocked by air, check on the probe, and it is ready for further tests.

Drawing of sandblasting apparatus for amateur use

It is necessary to clearly understand that the cheap fish is only in the factory dining room. Therefore, there and eat only if necessary. Sandblastrike is also a rather difficult device in the sense of materials used. The most important part of the apparatus is nozzle from which the sand jet comes. You can buy a professional high-strength nozzle that will serve hundreds of hours of work. It will cost no less than a hundred cu, but is there any point in this, solve everyone individually. The price of the apparatus directly depends on the materials and additional equipment, control of cranes and valves, but to a greater extent, from the nozzle or pistol.

In a word, if you collect a device from undergraduates and from what is in any economic store, then the following components will be needed.

The price of such a set should not exceed two and a half thousand rubles, and this is a minimum that allows you to make a more or less functional device. If we compare with the price of the finished sandblasting machine, then this amount looks like a ridiculous one.

Assembly and operation of the device

And now we turn on the fantasy and, following the basic rules, collect an aggregate. From the bottom in the cylinder drills the hole under the fitting, screwed it into place. We screw the neck from the two-link pipe. After that, it is worth assessing your capping capabilities. If the cylinder is heavy, then you can put it on the wheel chassis. This will facilitate transportation. If the balloon is small and easy, there will be a handle.

Actually, the main thing in this story is the several drawings that we have placed in this section and on the basis of which the self-made sandblasting apparatus will be assembled with your own hands. It is worth choosing the compressor correctly, it should bent for air in the range of 4-6 atmospheres, and the sand fraction should be about 0.5 mm. There is nothing archent in the device, so if there is a need for sandblasting, then this problem, like many others, is solved on their own.

The sandblasting machine is an indispensable tool at construction, especially when removing paint from surfaces and grinding of metal products. In one day of its use, you can perform the work to which you would have left the week if you used sandpaper.

Reliable and durable models are quite expensive, and therefore it will be described in the article below how to make the best sandblasting apparatus with your own hands.

Principle of operation

To start work, be sure to get acquainted with the scheme of the device. When choosing high-quality materials and components, you can create a device that is not inferior to the power and reliability of the factory. In addition, in comparison with the purchase, independently made sandblasting unit will be cheaper several times.

Made with their own hands and purchased sandblasts, works on a simple principle that is also used in the paintwork "Kraskopult". Unfortunately, there are items for which they differ, it is because of them the devices are not interchangeable.

The most important and responsible element of the design is the compressor. It allows you to organize a uniform and strong air flow in device hoses.

This is most often the most expensive item that needs to be purchased. It creates the air flow that flows through the hose, passes by the sleeves with the abrasive material, and capturing it goes through the nozzle.

Nozzle is also an important element, because it is constantly exposed to abrasive material and should be the most urgent. If you wish, you can make a nozzle from the car candle, but you need to pre-deliver electrical contacts.

Most sandblast owners are recommended to purchase them in the store, because they are the greatest wear resistance.

Necessary components

What you can make a sandblasting device, you can safely find in your garage or workshop, or purchase at low cost in the market.

In order to make a capacitance for abrasive sand, it is best to take a large red gas cylinder. It is made of high-quality metal and can be well to resist mechanical loads. In the bottom of the cylinder, you need to make a hole for backing up the abrasive and welcome in place its pipe with carvings.

A high-quality compressor, from which the quality of the device will depend on the device and the power of the device is the responsible part. Reliable and powerful compressors expensive. But if you wish, it can be independently made from undergraduate materials.

For its manufacture you will need:

Compressor heads from the car ZIL or MAZ;
Receiver. It can be made of gas cylinder;
Electric motor;
Frame for fastening elements.

You will also need the following simple and inexpensive materials and details:

Wear-resistant ball valves;
A strong reinforced hose, its diameter must be at least 14 mm;
An ordinary hose. Through it will go air along the hoses to the sleeve, its diameter must be at least 10 mm;
Fittings, for connecting together the main installation nodes;
Sealant for processing places of possible leaks, best fum-tape.

Assembly

Check out the photo, how to make a sandblasting machine with your own hands to simplify the assembly process.

The first thing you need to do is cut off the brass part at the top of the gas cylinder, and instead to prigerate the sleeve fitting. It is in this place that the stock Abrasive will occur. It must be remembered that a small amount of gas can remain in the cylinder, for greater security, use a ventilation compressor.

It is necessary to ensure that the seams when welding the seams are most sealed. You can also weld to a balloon wheels that make the installation of mobile.
Note!

Mixing abrasive material and air occurs in a sleeve, in which there are three fittings. The abrasive mixture is moving with a powerful stream along the reinforced tube. The last stage is the output of an abrasive jet out of the nozzle.

It is necessary to connect the details and at the same time to ensure their tightness, the fum-tape will help.

There are many other ideas and instructions how to make a sandblasting machine with your own hands. Presented is the easiest and most economical option.

Check out the schemes and drawings for self-making sandbostrutes. And purchase high-quality components capable of withstanding a long exposure to abrasive particles.

If seriously refer to the assembly of the device, it should function not worse than the factory

Note!

Conclusion

All the above tips and recommendations were to show how to properly make sandblasting apparatus with their own hands. The process is not heavy, but it can help you save and create a useful unit, the use of the use in which it can bring tangible benefits to enumerate.

Photo of sandblasting machines do it yourself

Note!

Sandblasting No wonder won the popularity of many people around the world. Using it, you can clean and degrease any details from the metal. It can also make glass surfaces.

Such a device can be easily bought in any construction supermarket, but not everyone can afford it.

Therefore, today we will tell you how to make sandblasts with your own hands.

Principle of operation of this device

The device produces an abrasive jet under high pressure, which is produced from the gun. At the same time, depending on what kind of processing materials you have chosen, such will be the end result.

In order to make sandblasts with her own hands, you will need a small compressor and building sand. In this case, such sand can be easily done, asking us the usual with a fine sieve.

Do not forget that when processing the surfaces of the sands flush under very large pressure and they can rickety from the treated surface even in your direction. Therefore, before starting work, protect your eyes and open skin.

Depending on what purpose you want to achieve, such a type of device and do. For example, if you process the glass, then make the device in the form of a camera, and if you clean the parts from the metal, then plan to collect open-type sandblas.

No apparatus will cost without a pistol. Let's start with him.

How to make a gun with your own hands?

The simplest pistol consists of a handle, tip and two fittings.

One fitting is used to enter the air under pressure, the other is intended for suction of sand.

We need to start the manufacture with the purchase of nozzles or nozzles. Through the nozzle will be emitted with sand under pressure. It is not recommended to pull yourself or make to order, as you can hardly get a good quality as a result.

The best option is to purchase a ready-made carbide, tungsten or boric nozzle. Believe me, it will serve you for a very long time.

Based on the size of the nozzle, pull the housing to the pistol. Bold the housing to the body and both fittings. The easiest way is to collect, using water fittings, a tee and a plastic container in which the sand will be filled (for it you can use a plastic bottle that you need to trim).
Such sandblasts can be collected with your own hands in a short time.

Bottles pour sand and connect to the second end of the fitting hose with compressed air, which is produced by a compressor.

It is used if you need to handle the details of a small size. In essence, this is a rectangular metal box.

Take metal corners and weld the cuskets of them. This frame is trimming using steel sheets (their thickness must be one millimeter).
On one of the long walls of the camera, refine the installation of a glass viewing window.

Cut two holes one hundred millimeters in diameter under a glass window. They are needed so that you can manipulate the objects that are inside. Bold gloves on them. Think how easy it could be replaced after wear.

Take a wire grid and make the bottom of it. Under this bottom, you have a chute, which goes into the container for collecting unnecessary sand. Inside place a gun, as well as bring the tube to it for air supply using the connector in the wall.

The sand hose is lowered in a box with sand. Now it turns out when the design works, the sand is poured back without leaving the working area.

In order to observe the grinding process in detail, install two light bulbs that are suitable in size. You can also mount ventilation in the product.

In the side wall, make a hole that can be closed (for example, in the form of a hatch). Through it, you will put the items that need to be processed.

Sandblasting with your own hands - another option

The gun is done using a plastic bottle with a capacity of one and a half liters. You also need to be stockpiled ball valve, a tee and a flavoring valve.

Please note that several parts you need to be pulled out with the help of a machine (if you are not a specialist in it, it is better to trust this work to the turner).

As an injector, you will use the liner. At that point where the tapered holes converge, low pressure will be formed. In this case, the air that falls into the container will continue to go through the hose, sucking the sand grains.

Using the crane, you can easily adjust the amount of consumable sand.

Using a threaded washer, screw the plug from the bottle to the mixer. Such a traffic jam serves not for a long time, so prepare for the fact that it will be necessary to change it from time to time.

What else needs to buy is nozzle from ceramics that is present in the dental sandblasting machine. This item can be easily found in medical stores.

As we have already noted above, this tool can also handle glass.

How to make engraving on glass?

The cut of the glass you need rinse, using self-adhesive film. Then draw any drawing and cut it through the contours using an office knife.

The resulting craft can be lit using LEDs. Will look very beautiful.

Small slicing sandblasting gun

Its only its disadvantage is that based on the dimensions, it will have to satisfy the sand in the container. But I think you can accept it.

For the manufacture you will need welding and soldering iron, because you will have to apply welding to one items, and to another soldering. The gun of this species easily withstands eight internal pressure atmospheres.

Trucks made of brass attach to a bank using epoxy plasticine.

To continue work, you will need to buy a gun for blowing a gun in the automotive store. It is glued with epoxy resin to the product.

As you can see, such a tool can be done at home. And considering his dignity and simplicity to use, I think everyone wants to have invested sandblasting.

Send the material to you on E-mail

Often, in order to remove rust from the body of a car or clean any detail, the motorists seek help to specialists, pay them a lot of money. Even the usual metal fence does not paint without stripping from rust. In fact, it is necessary to just understand how to make sandblasts with your own hands (the video will be presented in today's article), and these problems will be solved. The work will not require high costs, and the home master will have its own personal device capable of performing such a dirty work.

Sandblasting apparatus in the farm can be an indispensable assistant

Such an aggregate consists of several main nodes:

a compressor that creates the pressure required for the sandblasting machine;
cables through which voltage is supplied to the compressor;
hoses;
fittings;
cranes for adjusting pressure supply;
dispensers;
moisture separator.

However, one of the most important details of the device can be called a nozzle, through which abrasive passes under pressure. In industrial production, the coating for the steel nozzle is boron or tungsten. Such details are durable, but at home in the manufacture of their own hands, the sand blasting is not possible. Although here and the load on the nozzle will be a small, incomparable with an industrial scale.

Helpful information! For homemade installation, you can use conventional steel. It is not bad for the old car candle, from which the electrode is pulled out. Of course, the service life of such nozzles is minimal, but also the value is zero.

Sandblasting diagram: Some subtleties

In order for a respected reader to be easier to navigate in the unit of the unit, we offer to look at the schematic image of sandblasting. You will make sure there is nothing complicated in its device. The main thing is to understand the principle of his work, with which we will understand now.

What is the principle of action of a sandblasting machine: video and photographic materials

The principle of operation of the device can be compared with the paintopult. Many know that under high pressure the stream of compressed air captures in small particles of paint and makes it out through the nozzle. Here the principle is the same, only instead of paint is abrasive (sand). And although the designs of sandblasting devices may differ, the principle of operation does not change. And in order to clarify the remaining incomprehensible moments, we suggest viewing a very informative video on this topic:

What types of sandblasting devices distinguish

To answer the question of which sandblasting device is better, it is necessary to clearly understand for what purpose it will be intended. Depending on the application of the application, determine which type of device is necessary. Three main types are distinguished:

Important!If the processing of large areas or complex in cleaning elements is required, i.e. The use of pneumatic sandblasting, it is better not to regret money and hire professionals than to risk your life. Remember that there is no chance of a chance of a chance even on 4 atm the receiver of a chance of life.

Sand for sandblasting: what better to use

Not only sand is recommended for sandblasting. More often it is more profitable to use other abrasives. But for sandblasting devices, made with their own hands, the best abrasive will be quartz sand. Nobody will use them on too hard pollution, but (for example) in order to remove rust on the wing or the hood of the car before it is enough to cut this place, the quartz sand is quite enough.

It's important to know! Quartz sand can also be inhomogeneous. It should be understood that if polished is required, small, sifted fractions are used, and to clean the fence from rust before painting it is better to use non-slipped sand.

The size of fractions by applications is distributed as follows:

0.1-0.8 mm - smooth sinky sand produced glass matting;
0.3 mm - polishing copper, aluminum parts;
0.3-0.6 mm - paintwork coatings;
0.6-0.16 mm - deeply entered rust.

In other cases, larger and rigid abrasives are used.

Understanding in which area sandblasting will be used, it should be paid to the fact that such equipment differs in the following characteristics:

the volume of the bunker for abrasive - The ease of operation of the operator will depend on this. The larger the volume of the tank, the less you have to stop during operation;
working pressure of the aggregate - for domestic use apparatus with a pressure of 4-9 atm;
performance - the optimal is the indicator of 15-30 m 2 / h;
sand consumption in the process - average for simple sandblasts - 40 kg / h;
equipment;
the number of operators involved in the work.

Special attention should be paid to the nozzle. It is from him that will depend on the performance, and from the material of the manufacture - the frequency of its replacement. Ceramic and cast iron nozzles are considered more acceptable - they work for a long time, and they are inexpensive.

The compressor should produce at least 350 l / min, otherwise you will have to install a large receiver, which will affect the mobility of the installation, which in itself is an important factor when choosing a device. Additional functions, the presence of which is desirable, can be attributed to the remote control of the supply of abrasive. This allows you to spend less air, sand and provides additional safety to the operator.

What tool will be required for the manufacture of sandblasting

The first thing to be purchased for the manufacture of sandblasting is the compressor, it will not be possible to make it with your own hands. Next - the reservoir for sand (abrasive). For this purpose, a propane cylinder or an old fire extinguisher will fit well. Now nozzle. Of course, you can pull it on the lathe, but then you need to be prepared that such a nozzle will quickly erase. The access will be the acquisition of special ceramic caps that will protect the metal. Hydraulic hoses from construction equipment are perfectly suitable as air ducts and channels for sand with air under pressure. You should not forget about the fittings, nozzles and cranes - their number can be calculated according to the drawing, without which the production of sandblasting is impossible.

What you can make a sandblasting device with your own hands

The most simple is the manufacture of aggregates from gas cylinders and fire extinguishers. At home the best foundations do not come up with. Now briefly consider the algorithm of actions that need to be performed.

Sand blasting from the gas cylinder with your own hands: Step by step instructions

Variations of aggregates created by their own hands from various tens of tens and hundreds. Sandblasts can also be made from the relevance of devices and parts.

Illustration	Description of action
	Let's start with the fact that we will do the center in the center in the bottom of the gas cylinder. For this, in a circle, we take a thin drill in a circle, after which we take the circle of pliers.
	In order for the hole to look more carefully, we break it with a drill with a special nozzle, although it is optional. Seen ripped edges will not be anyway.
	We weld the cap with the screw plug - through it it will fall down in the sand tank.
	Prepared all the splits, tap fittings and hoses, you can start work. Be sure to have a dryer! The fact is that when the compressor is working, condensate is formed, which leaving compressed air, wet the sand, and the wet abrasive just scores the nozzle.
	We are trying to unscrew the valve of the gas cylinder. It is rarely obtained without difficulties. In some cases it has to cut, drill the remaining inside and straighten the thread.
	After the valve is removed, a split is screwed into a ½ inches. It is not necessary to pay attention that carving on the cylinder cone.
	All threaded connections flush pakrels. As an alternative, you can use FUM tape, however, the old good panel is more reliable.
	If you do not plan much work, you can use the tip from a cheap thermopystole as a nozzle, which is sold in Fixprise stores.
	This is how our sandblasting apparatus of pressure type looks like. Of course, the appearance may differ, but the essence does not change.
	Such an apparatus can not only process the metal, but also to make the glass, which we tried to do on the example of a simple bottle.

Is it difficult to make sandblasts do it yourself from the fire extinguisher

If you figure it out in detail with our step-by-step instruction, it will not make a sandblasting unit from the labor fire extinguisher. Everything is done here exactly. The only difference will be the size of the sand reservoir.

How to make a sandblasting nozzle with your own hands: Editorial Tips Website

The optimal option will be the manufacture of a ceramic nozzle for sandblasting from the spark plugs worked out. To do this, turn out the central part, after which the nut cut the candle with the grinder. It should be done carefully so as not to damage ceramics. After the work done, the ceramic glass is easily removed. Of course, such nozzle will work no more than 2-3 hours, however, the whole charm here is that it will not cost anything - old spark plugs can be found as much as you like. If you get nozzle, then it is best to buy a boron carbide product. It will last from 750 to 1000 hours of continuous operation. The cast-iron nozzle is enough for 6-8 hours, and tungsten carbide products are about 300 hours.

Production of sandblasting pistol with their own hands: how difficult it is

The manufacture of gun for the sandblasting apparatus is a completely simple. This requires only a pneumatic equipment, with which it blows hard-to-reach plastic bottle. We offer our respected reader to view a short video in which the process of manufacturing a sandblasting gun for the compressor is explained in detail.

How to make sandblasts do it yourself: video tutorials for the manufacture of various units

Such installations can be different types. Now consider the processes of their manufacture. Let's start with an ordinary homemade sandblasting machine with your own hands. The video presented below will help more fully understand our respected reader, how to do it.

Frequently covered spark plugs? Then a good output will be constructed and make sandblasts to clean the spark plugs. As it looks and how it is used, you can learn from the video.

And from the following video, you can understand how the sand blasting apparatus is arranged. A fairly interesting solution that will not require much costs, if there is a mini-sink of the Keurger type at hand.

Well, if it is decided to make a sandblasting chamber, the editorial site presents to your attention a few empties made according to the drawings.

Pros and cons of homemade units

If we talk about the positive sides of the sandblasting devices, collected by their own hands, then they are on the surface - it is an opportunity to clean the surface for a very modest amount that the master will spend on the taps, fittings and pipes. And that if this is not in his garage. This pluses end. And what about the minuses. Here is a question of time. Distribution when working is clear, and how to be with trauma? Any embossing when welding details will lead to a rupture in this place. In this case, death is possible. Therefore, the editorial board warns: 1000 times we suspend and think if you can make this job perfectly qualitatively. If not, then it is better to refuse.

If you do not have time and desire to do your sandblasts, you can always have our partners

The sandblasting machine is an unusually useful and necessary device, which is successfully used for several decades in various fields of industry. With the help of this device, metal parts are cleaned and degreased, and glass is matted.

You can purchase a sandblasting device in any store, but a good device is expensive, and economy class models are often summarized as. Therefore, an excellent option will make this device with your own hands. Homemade sandblasts are not deprived of flaws, which are overlapped with simplicity, quite a decent performance and low cost. With the help of such an appliance, you can independently carry out various works - remove rust, mold glass.

Principle of operation of the sandblast

Many wonder - how to make sandblasts? The main thing is to determine the principle of the instrument. The device works like this: an abrasive jet under high pressure flies out of a gun. The finishing result of work depends on the selected materials.

In order to make a homemade sandblasting device, you must have a small compressor and a building sand that does not have to buy - it is enough to sift the usual through fine sieve. Depending on the tasks set, the quality of the sand used is selected. For work on cleansing metal surfaces, the sand of medium or poor quality is quite suitable. Working with the sandblasting machine must be taken care of their own security, namely protect the eyes and open areas of the skin.

After studying the main aspects of the work of the sandblasting machine, as well as the scope of its application, it is necessary to determine in which the manufactured device will be used. If the appointment of home-made sandblasting will be decorative glass processing, you need to make a sandblasting chamber if the cleaning of metal parts is an open-type device.

It is also necessary to pay attention to how often the device will be used, at what level - professional or amateur. Based on the data obtained, it is possible to determine exactly what materials and what quality are needed, the estimated power and performance of the device, etc.

The easiest apparatus - Sandblasting pistol

Homemade sandblasts consists of two main parts - handle with a tip and two fittings. Before starting work on the manufacture of the device, it is necessary to choose nozzle - an air jet with an abrasive material is thrown through it. It is better to buy this detail, it makes no sense on your own - the desired quality is most likely you will not achieve. Then the housing of the gun is manufactured under the nozzle, then two fittings and handle are connected. The easiest version of the homemade sandblasting consists of plumbing fittings, a tee and a plastic bottle. In addition, a compressor airflow is supplied to the pistol. The sandblasting scheme is shown below. An example of a finished device in the picture. You can also watch video and drawings on our website.

Consumables for sandblasting

As it was written earlier, an ordinary sacred sand can be used as consumables, but only if it is about cleaning. In any other cases, special abrasive materials that need to be bought are used. Buying consumables, it is necessary to pay attention to the hardness, size and shape of the grain.

Sandblasting camera

During sandblasting works on large areas, the abrasive is quickly spent - a considerable part of the material is simply scattered. To improve the efficiency of work, a special sandblast is offered - camera. It is a metal coated box, covered with steel sheets. This design is ideal for handling small details. Make a camera with your own hands is not easy, but quite really even a newcomer. The design for convenience is placed on the table. On one of the long sides of the chamber, it is necessary to place the sight glass.

In front of the design you need to foresee two holes with hand gloves. The bottom of the design is a wire grille. Under it there is a special chute through which the spent consumable material comes out. Inside the design is a pistol. The camera is illuminated. It is advisable to equip it with ventilation. Sand blasting on video can be viewed with us.

Sandblasting apparatus pressure type

If you wish, you can make homemade sandblasts of the pressure type. For this it is necessary a metal barrel with a cropped bottom in which the cone is installed. At the bottom you need to attach a shutter with a tee. It is connected to the hose from the compressor and the sleeve with the nozzle.

The article only approximately describes the basic principles of work and the manufacture of sandblasting apparatus. In case you need to make a device of this type, the reader needs to carefully calculate and think over.

With the help of a sandblasting machine, you can cut holes on glass surfaces. To do this, take a metal plate, the thickness of just a few mm and cut the hole in it. Then you need to apply a sheet to the surface and start processing the surface. This procedure takes about five minutes and takes the shells of sand. The advantage of this method is rapid, cheap work with a smooth hole without chipping holes. Sandblastrike shows excellent results in various applications, both amateur and professional level.
