With all respect due to Evan, I have to agree with Carl and Alvin. One of the best things I ever did was get rid of my pressure pot sand blaster. I'm with Alvin -- if it doesn't fit in the blast cabinet, I pay someone else to do it. If you don't have a professional set up (ginormous compressor and water filters/separators sufficient for the task), it's just an exercise in frustration.
