Usually sandblasters 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 the processing of parts to separate them from various inclusions or burns. The third case of using a device such as a sandblaster is considered the most interesting. He suggests that this device will be used as an artistic tool.
That is why when making it, it is necessary to take into account all the features of its application. Although there are such models that can be used in all the proposed cases. They are distinguished by a movable nozzle design 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 first 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 easilycarry it.
You will also need a container for sand, which could be easily moved during work. An ordinary homemade sandblaster can use a small amount of sand, so a plastic bottle or used fire extinguisher can be used as a container. When using such a container, it is recommended to hang it upside down during work.
Next, you will need a standard factory air gun or airbrush. They make the sandblaster 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 outlet nozzle. It fits perfectly with a standard air gun, and when mounted on a spray gun, you will need to use an adapter.
Standard ceramic nozzles must be installed on the opposite outlet of the tee. At home, they are placed on a jewelry or dental sandblaster, and they can be purchased at the appropriate store. It is worth noting that nozzles made of other material are not suitable for this purpose, since after a few minutes of use they expand the outlet, which reduces pressure.
To the third hole of the tee installed on the sandblaster, attach a container of sand. Moreover, if it is a plastic bottle, then it can be mounted immediately on a tee, and if a fire extinguisher or other largecontainer, then it is connected with a hose.
After connecting all the parts, the sandblaster will be ready. Various fractions of electrocorundum or sifted building sand are used as sand.
All work with the sandblaster must be carried out in goggles and using a respirator. This will protect your eyes from sand and your lungs from fine dust.
