Re: My Homemade Sandblasting Pressure Pot
This picture shows the bottom of the tank with the sand control valve, it's a bit touchy and I wish there was a better way to control sand flow, but this is the best I've come up with so far. I tried to keep the welding to a minimum, but I needed to drill a hole in the bottom of the tank, over that hole I welded a 3/8" pipe coupler. My welding doesn't look so good in the picture, as well the bottom looks a little rusty, not the sort of thing you want to play with, I may retire this tank and redo it just to be safe, I can reuse almost everything and a new tank is only $20.
