Response to Will a 3/4" ball valve work as an exhaust valve?
3/4 should work but a one inch sprikler is really the best way to go, there only like 10 bucks. the 1/4 valve wont work because there is probally 1/4 worth of gap around the piston in the chamber. the volume of air needs to dump really fast for a piston exahust cannon to fire.
