[edit] How to build them

  • Interior coating can be made from something soft, rather than hard (rubber?). Norton Sandblasting Equipment sells rubber curtains for this purpose. Spray-in bedliner has been suggested.

[edit] Where to get media

Locally, online, cheaply?

[edit] Dealing with dust

When the blast media wears out, it will create more dust. Also, can use a dust collector.

You need air flowing into the cabinet, as well as out.

Some creative solutions on dealing with dust are here: http://www.hotrodders.com/forum/blasting-cabinet-clouds-up-136430-2.html .

[edit] Blast cabinet visibility

Try an external light or two shining in the blast window, or inside the blast cabinet.

Window can be made of tempered glass, with a replaceable polycarbonate film taped to the inside.

[edit] Shop vacs

You can burn out a shop vac using it to evacuate a blast cabinet -- the media is so small it gets into the motor, and can be abrasive. Also, the paper filter gets clogged very quickly. One suggestion is to wrap the filter with a layer of foam (like some car filters). Shop vacs have low CFM compared to most suitable fans, so they aren't going to work very well -- you need a more powerful fan.

[edit] Recycling media

  • Don't recycle media that has been used to blast undercoating -- it contaminates the media.

[edit] Safety

  • If you're getting media outside of the cabinet, you'll need to wear a mask.
  • The blast media can be slippery on a hard surface.
