I think Ive given up on making a piston gun, never going to work lol

Good point haha, Its a half inch piston of pvc filled with hotglue. Its 2 inches long.

Hey guys I finally made my pneumatic barrel sealing piston valve air gun but when I release the air in the back the piston does not come back, I think it might be to snug of a fit.


Any help would be appreciated thanks,

8) Yep lol Im trying to make a simple piston air cannon for my first try on a piston valve, have not made them before so il need help and a design:P.
I would prefer it to be a PVC design.


If that is possible it would be greatly appreciated by me.

Thanks

Fuller.

Yeah I have won that is already moddified for my tennis ball cannon, it is a 1" sprinkler valve with a blowgun and jb weld in the solinoid valve spot.

Thanks

But does anyone know how to make a piston air rifle or is it a good idea to not use PVC for these smaller guns?

I have recently constructed cobblers marshmallow gun, COPIED EVERYTHING AND AIR WENT RIGHT OUT THE BARREL!, got me angry lol. So I am wondering if anyone has a simple design for me to make a piston air gun. Preferable 1/2" barrel.

Thanks, P.S. im new!
