Hey this is my first cannon it's a copper pneumatic one using a ball valve. It's all 15mm. I've taken it up to 160psi with my joe blow sports pump. To put the schrader valve in I stripped the rubber off in a drill, unscrewed the poppet sooldered it in and put teh poppet back. I t was my first go at soldering so don't be to harsh. The most damage I've ever done was a nut and bolt through 6 ply and 1/2innch mdf.
Stats
Chamber: 7 feet of 15mm
Barrel: 5 feet of 15mm
Valve: ball valve 15mm
Filling valve: tyre valve
Here's some pic's

I was originally going to buy a schrader that fits into a 22mmm endcap.spud yeti wrote:WOW! :wav: :occasion5: :headbang: Thats so awesome I forgot to jump up and down... Yeah, its OK. Why the massive amounts of copper at the bottom though?
And spanerman, I got the stuff at homebase and they only sold 22mm copper in 30m lengths for £113...I probally will springload the valve[/quote]
