one more question how would we get the air from the air tank to teh ari chamber we were planning on running the air tank to a reg and then into the air chamber on the canon. ho would we get the air into the chamber with no leaks at around 500 +- psi

okay so steel pipe is fine for high pressure as long as it is sch 40?

Also will 900 psi be over kill i wouldn't think so but i would like to know?

i was planning on using around 200 psi but the max i would use is 900 is that over kill? also would steel pipe hold that much pressure?

so me and one of my friends are building our second pneumatic potato cannon, so we have a little experience. This time around we are going to run the cannon off of compressed air from a bottle, like the kind on paintball guns.

how would we get the air into the air chamber. we were planning on ...
