Pictured above is an abrasive blaster that sells for about $600 at Northern Tool (and about a million other places). I have a 40 pound propane tank and a set of wheels that would give me a good head start on the materials that I need to make my own version. Some parts that I would need to buy would include a deadman valve/blast gun/nozzle holder, some blast hose, assorted pipe fittings and valves, a water separator, and a pressure relief valve.

Blast hose is the most expensive item, running about $10 a foot. A deadman style blast gun would run about $55. I figure I might have $250 or $300 into the entire project by the time I’m done. In any case, after calling around to get some prices for sandblasting services, I can see that this thing will pay for itself in no time.
