I recently bought a small sandblaster and after first putting it to use inside a small cardboard box with a plexiglass lid I decided I could invest a little time into making something a lot better. What we have now is really a fantastic little unit.

The gun and media are fully contained within the cabinet. The hopper collects and recirculates the blasting media. The air pressure is provided at a fitting on the outside of the cabinet. Connecting a vacuum is a good way to maintain the visibility, but I have had to toy with good ways to let air into the box — otherwise there is such a powerful negative pressure within the cabinet that the gloves balloon out like a pressurized astronaut suit.

Replaceable neoprene panels are incorporated on the sides of the cabinet to accommodate longer pieces that would need to pass through the cabinet to be surfaced. All of the components can be replaced by turning a few nuts.
