Re: How to build a pneumatic air cannon
Pressure rated PVC is non existent in Ireland I think, All to the same pressure I believe but where DeAd is in the US I have no doubt but he did!

Re: How to build a pneumatic air cannon
Pretty bad, but He also sells CaC2 so I don't mind paying through the nose for shipping.

Re: How to build a pneumatic air cannon
Hey delusional_reality its just schd 80 cpvc( the stronger grey stuff)pipe, with cpvc glue. I hooked it up to the air compressor and gave it 125 psi with no signs of stress. But i only pump it to 40 50 psi to shoot.
The volume of air is just as important as pressure. What I want it a semi auto, magazine fed, gas powered mashed tator maker.
