Copper piston cannon

[SpudStuff]

This is my copper piston cannon. I have taken it up to 500 PSI with CO2.

Chamber--3/4" x 68" 30 CI
Barrel -- 1/2" x 70" 13.3 CI
Valve-- Copper Bolt Piston
Special Features-- Made of Thick Walled Type L copper pipe. I have taken it up to 500 PSI with a CO2 Bottle off of a paintball gun.

Holy cow, 500 PSI. If anything goes wrong you will probably end up with a chunk of copper in your side.
I'd really like to see some destruction shots from this gun. It sounds like it would be really powerful.

copper dosn't shatter it spluts. if it was to break it would most likely split open on oneside of the chamber more photos to come

woa 500psi seems like your pushin it a little too much if you ask me. but besides that i bet that thing destroys anything you shoot it at. id like to see some damage pics also

What is your piston bumper made out of? I imagine that a piston slamming back with that kind of pressure could do some crazy damage to the gun itself.

actually the bumper is a spare 1.8 rate shock spring off my traxxas revo rC car ~18 pound compression
