All they wanted was 18" down on the inside and the top and sides. I used coarse Newage glass, 185cfm with a #7. Cut the coating like butter.

Nice job, #7 is supposed to be too big for a 185 cfm. What pressure were you shooting at?

My gauge is showing a consistent 70psi after about 1min of continues blasting. I'm running electric deadman so that helps. The 185 is running full speed while blasting. It's nice to stop blasting for a few seconds and let the pressure build up and then hit it. I'm in the market for a used 375cfm if you know of one.



Last one was before it was drained.

You probably had around 50 psi at the nozzle then, depending on how much hose you had on your compressor and blast pot. And of course size of hose too. 3/4" air hose and 1" or 1 1/4" blast hose. That little compressor was huffing.

Yeah, it was running full tilt.
