Usually sandblasting machines are used in several cases. The first involves the processing of parts in order to create a clean surface for further coating. The second - involves processing parts to separate them from various inclusions or burns. The third case of using such a device as a sandblasting apparatus is considered the most interesting. He suggests that this device will be used as an artistic tool.
That is why in its manufacture it is necessary to take into account all the features of its application. Although there are such models that can be used in all proposed cases. They differ in the movable design of the nozzle and the ability to move it to a position convenient for the user. Therefore, this design is called portable.
To make a sandblasting machine with your own hands, you should initially purchase a compressor unit. For these purposes, a conventional construction compressor with a receiver may be suitable. It is desirable that it be small in size so that it can be easily transported.
You will also need a container for sand, which could be easily moved during operation. A regular home-made sandblasting machine can use a small amount of sand, so a plastic bottle or a used fire extinguisher may be suitable as such a container. When using such a container, it is recommended that the process be suspended by hanging it with the outlet down.
Next, you will need a standard factory air gun or spray gun. 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 mount an ordinary water tee on the output nozzle. It is ideally suited to a standard air gun, and when mounting on a spray gun you will have to use an adapter.
Standard ceramic nozzles must be installed on the opposite outlet of the tee. In domestic conditions, they are placed on a jewelry or dental sandblasting machine, and you can purchase them in the appropriate store. It is worth noting that nozzles of a different material are not suitable for these purposes, since in a few minutes of use they have an expanded outlet, which reduces pressure.
A sand container is attached to the third hole of the tee mounted on the sandblasting apparatus. Moreover, if it is a plastic bottle, then it can be attached directly to the tee, and if a fire extinguisher or other large container, then it is connected using a hose.
After connecting all the parts, the sandblasting machine will be ready. As sand, various fractions of electrocorundum or sifted construction sand are used.
All work with the sandblasting apparatus must be carried out with goggles and using a respirator. This protects the eyes from sand and the lungs from fine dust.
