Gas canisters

[truemanator]

hi, i have a few gas tanks (large propane gas canisters) at my disposal, and want to build a badass cannon with the gas canister as the pressure chamber, any suggestions on how to do this?

Have a look here for a QDV using large propane tank.

That seems abit complicated for me, mabe i should do something smaller first, i was thinking it would be: schrader valve-pressure chamber- ball valve- barrel (maybe alot smaller than a gas cannister). Would this work ok?

Then do not say badass cannon, just say I am new and want to build my first pneumatic cannon.

First do a little research in the pneumatic section.
