How to make a sandblaster yourself
Typically, sandblasters are used inseveral cases. The first involves the processing of parts to create a clean surface for further coating. The second - involves the processing of parts to separate them from various inclusions or fumes. The most interesting is the third case of using such a device as a sandblaster. He assumes that this device will be used as an artistic tool.
That's why when you make it, you needtake into account all the features of its application. Although there are also such models that can be used in all the proposed cases. They differ in the mobile design of the nozzle and the ability to move it to a user-friendly position. Therefore, this design is called portable.
To make a sandblasting machine yourhands, you should initially purchase a compressor unit. For these purposes, an ordinary construction compressor with a receiver can be used. It is desirable that it be small in size to be able to easily carry it.
It also requires a sand container, whichcould be easily moved in the process of work. A conventional homemade sandblaster can use a small amount of sand, so a plastic bottle or a used extinguisher can come up as such a container. When using such a container, it is recommended to hang it with the outlet hole down during the work.
Next, you need a standard factoryan air gun or an airbrush. They make the sandblasting machine easy to use and portable. It is necessary to connect a hose from the compressor to the spray gun, and to mount an ordinary water pipe tee on the outlet nozzle. It is ideally suited to a standard pneumatic gun, and when mounted on a spray gun you will have to use an adapter.
To the opposite outlet of the teeit is necessary to install standard ceramic nozzles. In domestic conditions, they are put on a jewelry or dental sandblaster, and you can buy them at the appropriate store. It is worth noting that nozzles made of a different material are not suitable for this purpose, since for several minutes of use they have an expanding outlet that reduces pressure.
To the third hole of the tee installed on thesandblasting machine, attach a container with sand. And, if it is a plastic bottle, then it can be fastened directly to the tee, and if the fire extinguisher or other large capacity, then it is connected with a hose.
After joining all the parts, the sandblasting machine will be ready. As the sand used various fractions of electrocorundum or sifted building sand.
All work with the sandblaster should be carried out in goggles and using a respirator. This will protect the eyes from the ingress of sand, and the lungs from fine dust.
