Hay thanks for the tip about the check valve. I think the pressure switch might already have the blow off thing, when I turn it off it depresses a valve that releases air from the pump by a pipe. Is that the blow off?
I picked up some stuff at lows and I think I got everything I need to wire it in.
As for the air hammer I think I’m going too put that off for a couple of years, and just build this for know.
