Hey this is my first pneumatic cannon, it is a good old ball valve, don't have the time or money for a modded sprinkler valve, and i don't mind the ball valve
iv used:
2" pvc pipe for air chamber
1/2" ball valve
adaptors
elbows
15mm barrel my marbles fit perfectly
i pump it to 150 - 200 PSI
it is all pressure rated

check out me shooting it

Nice, simple.Apparently my pneu was gonna look EXACTLY like that too. what kind of adapters did u use for the 15 mm barrell?

i used 15mm adaptors that fit the pipe very tight and when i glued it, it made it easier to push in and pressurized it.

Hey simo, cool gun, mine kicks your ass though! lol

No worries thursto
i will get some damage pics and vids soon

Nice gun! I'm glad there <I>are</I> pics.

flamerz14: I think he ment a 15mm to 20mm bushing (or w.e the ball valve is) to a 20mm coupling into a 20mm male-to-20mm male threaded.

Nice first mate, and welcome to your new addiction. 8)
