I've always wanted to do something with copper, but at $5 a foot for 1/2" type M, it's just too damn pricey for me.

Yes it is, it's a co-axial (barrel concentric with the chamber) with a piston valve, look here to see how it works.

I'll have to look for that next time I'm at the store. I always hate how epoxy is so brittle pieces always get chipped off.

Jon_89: The shots were fired from ~2 inches away.
would'nt it be hard to drill and tap it if its all stretchy?

I feel your pain when you're on about the pump limits. I've actually bent my pump shaft trying to get some more pressure out of it. Even at 155 lbs in weight , I have difficulty getting above 200 psi with the pump I have.
would you mind posting the gun you use at this pressure? Ive never seen any of your work and it sounds very good.

Actually, now you mention it, I realise I haven't posted any of my cannons in months.
I really should I suppose, so I'll get that sorted then.
