Sandblasting from a bottle: this is possible

The most effective process for cleaning surfaces from corrosion and old paint is to use sandblasting machine. Outgrains of sand melting under high pressure take with them all that is superfluous, leaving the surface perfectly clean. The only problem is the cost of the sandblaster. The simplest one costs from 9,000 rubles. But if you have a compressor at home, even a homemade one, you can build such a device in just a couple of minutes. Yes, it will not be as powerful as the factory model, but for urgent work it will be fine. The author of the YouTube channel shared his experience in creating such a device. Workshop Palych Live. And if you need to quickly clean something, then you can repeat its design without much difficulty.

What is required to create a sandblaster

The principle of operation of the sandblaster is based on an air compressor. It is he who creates the necessary pressure to accelerate the sand particles. So the first thing you need to prepare is the compressor. You can make it yourself, for example, from a fire extinguisher and refrigerator parts.

And one more important detail of the device, on which you do not have to spend money at all: this is the most ordinary plastic bottle, which is affectionately called by the people a " poltorashka". It will be used as a container for sand — And one more important detail of the device, on which you do not have to spend money at all: this is the most ordinary plastic bottle, which is affectionately called by the people a "poltorashka". It will be used as a container for sand

How to collect sandblast from a bottle

To make a sandblaster, you will need to make a nozzle in which the sand particles will accelerate to work.

A regular nozzle from a blow gun will not work, so you need to remove it, and instead select a tube of a suitable diameter with a length of about 40 cm

The author found that these are the right pipes that are in the radiator of the refrigerator. It is not difficult to select and cut a part of the required length, and then you just need to clean its surface from the remnants of the radiator wire

It should be noted here that during active operation, the nozzle will gradually become unusable due to high friction, so you can immediately prepare several of these tubes for further work.

Insert the tube into the air blow gun and mark the distance from the attachment point, approximately 4 cm. Here you need to make a gash - a hole through which the sand will fall into the tube. You can make a gash with a grinder with a cut-off wheel

Choose a drill bit that is the same diameter as the tube. You will need it in order to make a hole in the bottle.

The hole must be made through the neck along with the lid. The tube should fit tightly into the neck so that the sand does not wake up by

A very important point - the sand for sandblasting must be dry, wet sand will clog the nozzle and nothing will work.

Before work, the sand must be very carefully sieved through a fine sieve, this is also an important condition for the successful operation of the apparatus. There is ready-made sifted sand on sale, if you do not have time for this

You need to fill the bottle with sand. Use a funnel for this, by the way, it can be made from the same bottle.

Now all that remains is to thread the nozzle rod into the bottle so that the hole in the tube is exactly in the center of the neck

Practical tips for using a homemade sandblaster

First of all, before work, you need to make sure that all parts of the device are firmly connected to each other. If the compressor has a pressure adjustment, check it and set it to the desired position.

Be sure to use a protective shield. Grains of sand can enter the eyes and respiratory system. If there is no screen, replace it with glasses and a mask. Be sure to wear gloves, especially if you are working with parts that need to be handled

The sandblaster has certain rules for working. If you use it to clean metal parts from rust, then the nozzle should be directed at an angle of 80-90 °, so the surface will be cleaned faster and more efficiently. But the paint should be removed at an angle greater than 90 ° so that the flow of small particles lifts the paint layer, tearing it off the surface.

Even with a rather weak compressor from the refrigerator, the author got an excellent result. He showed how homemade sandblasting can easily remove paint and scale from metal objects.

It must be admitted that this device is much more effective than any hand tool and even a grinder or drill with abrasive nozzles. The device can be assembled very quickly, literally on the knee. And if you have a car, then use a compressor to inflate the wheels in this device.

By the way, a simple compressor can even be made from a car wheel, here is an example of such an alteration in a video:
