proper piston fit and seal
Posted: Tue Jun 02, 2009 8:34 pm
Hey all-
I've got to make the piston for my undermount paintball launcher, and it is a toolies valve. IT's in a 1.25" galvanized nipple, and seals against a 3/4" nipple.
It's going to be using unregged CO2.
For the piston i was going to cast one out of hot glue. would that be a good enough seal if it was cast in the pipe it slides in would be good enough? Then i would have a support washer, and then the sealing face.
Would that work, seal enough and still be able to open?
Or i was maybe thinking two washers with a neoprene washer in between for the piston- that would give a very good seal but then how would I get it to let air into the chamber portion? Would the neoprene just be able to kind of flutter?
I need to get this right the first time pretty much, in 3 hours preferably. I need it for thursday and can only work on it tomorrow...
