We have a smaller pressurized pot sandblaster that I think we had purchased from Tractor Supply or Harbor Freight. I can't remember which anymore. It uses ceramic nozzles and of course it goes through them like crazy. I am sure nothing is going to hold up for too long but something has to be better.
The current valve it uses is a ball valve which works. I know some of the deadman valves have a lever that also closes the tip of the valve. Curious to know if anyone has any suggestions on a decent valve and nozzles?
