Can you tell me about your sand blaster setup?
Kind of primitive but it works great. I like SB outside even though I have a cabinet. For the big stuff I use play sand. I roll out plastic for a floor, then make shift a couple side walls with scrap drywall or plywood whatever I have to keep the sand from escaping. This allows me to re-use it several times until it gets too powdery. I start out with the sand in a bucket with a siphon hose. After awhile when it starts to pile up I just drag the pickup tube along the piles by my feet. I occasionally stop & sweep it closer to me. For some reason I have always liked limiting the amount of sand to the pickup tube. When it lays in the bucket it draws too much sand & doesn't work as well. Now before everyone starts complaining at me I know using play sand is not recommended. I take all the necessary precautions. I did have a pressure pot but I never could get it to work very well. It was a cheapy from NT, I had to send it back for a refund. Hope this helps.
