Make a DIY Sandblaster

Dec 18, 2023Dec 18, 2023

It'll take four empty LPG canisters, a welder, laser cutter, and plenty of fixtures to build your own sandblaster.

To build a sandblaster you need a way to harness compressed air and sand, and a way to send it through an applicator gun. This is much easier said than done, but the skilled metalworkers at Make It Extreme have found a way.

They started with four empty LPG (liquified petroleum gas) canisters, and proceeded to cut the tops and bottoms off using plasma cutters, creating two large canisters. Then they cut holes for various air fixtures and also made a rolling cart which makes the unit mobile.

An applicator gun was built from pipe, and then all of the hoses were tightened up and sand was added to one of the canisters. The final test was to add pressurized air. After that? Time to start blasting. The sandblaster quickly removed old paint from the cans and then started blasting paint from sheet metal and wood.

This is an advanced project requiring heavy use of a welder and plasma cutter. You can do this at home, but you're gonna need a lot of a equipment and definitely want to have a more than a few metalworking projects under your belt before you attempt this.
