I made a blasting cabinet out of a 55 gal. drum.I used one with a lid that can be removed by undoing a clamp ring. The hoses go in through the threaded holes used to fill and pump out normally. I cut a square hole in the side to use as a window. Made a 2X4 frame with a slot cut to slide plexi glass in and out for the window. Above that I cut a round hole and riveted one of the clamp on aluminum work lights from the hardware store minus the clamp for light. Under the window I cut 2 holes and riveted old jacket sleeves to them. Set that on saw horses and you have an instant blasting cabinet and all the sand is contained for reuse.

EDIT: If you decide to make one don't skip the light, you will need it.

I learned all I need to know about life by killing smart people and eating their brains.
