Hey guys this is my new cannon. It's pretty much made out of poly except for the barrel ect. Urgh I'd tell ya alot more but I had just completely typed up everything about this gun, had it all ready so I pushed submit...and it said page can't be displayed so I lost everything :evil: :evil: :evil: . I know it's only got a ball valve and a coke bottle chamber but I have a heavily modded sprinker valve and a 32mm chamber all ready. I've just gotta get a few parts to attatch em.

If ya got any Q's, drop us a line.

Mitch.

Nice,does the piston have much room between it and the nipple?Does much air come out the pilot?

Ohh one thing...Go The Coke Bottle!

it worked beautifully with the ball valve but now with the spirnker valve, it doesnt work at all. thats why i need a lighter spring. that could be why the piston doesnt go back.

Do you know what pressure poly pipe is rated to....because i want to know.......btw i can't see the pictures

I searched....and it said that

..Rural Poly should not be connected to Mains Pressure..
but
..PN12.5 metric poly pipe can be legally connected to mains pressure..
