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