Hey guys.... The cannon broke :( The part of the barrel that was epoxied to the Tee has given way. I've had to totally rebuild the valve. Luckerly I was able to use alot of the parts I originally had. I've come up with a way that the barrel is screwed directly into the T so no more weak cheap arse epoxy :D Plus I've made a whole new piston from scratch. Its made from aluminium, the pilot has been reduced a hell of alot, the piston slides effortlessly and when the piston does move back to open the valve, it completely seals up against the back of the Tee so I don't lose any pressure :D So far this has been my most fidly cannon but I'm sure I'll get some insane results.

Mitcho.

Nice gun man! I only think you should build a pvc chamber and paint the valve, it's nice to paint it!
