Re: T-shirt Cannon revolver seal

I would not recommend a sprinkler valve, just because I've read threads suggesting the same and concerns about how safe it is.

We based off our T-Shirt cannon off of 254's Shockwave and like Squirrel mentioned

Quote:
YOu need a pressure regulator, as well as a large diameter solenoid valve. and probably a second storage tank, and another solenoid valve (at least that's how we did ours years ago)
We did the same. We have a 3000 psi SCUBA tank connected to SCUBA valves that run to a 5000 psi pressure gauge and 150 psi regulator (this is the outlet for the pressure for the diver). We then adjust that regulator from 40-150 psi depending on the venue we are shooting in (small or HUGE). The air from the regulator fills a secondary SCUBA tank that accumulates the air for each shot at a much safer pressure than the main 3k psi SCUBA tank. The solenoid that lets out the accumulated air for each shot is a 1" NPT MAC solenoid, similar to the one on Shockwave.

We have a gap of about half an inch (yes I know it's quite a bit) between the exhaust valve and the barrel but the maximum range is still about 200 feet.
