Do they need to have o-rings?

Is it possible for it to crack? and whats the best way to attach the sealing face?

Hey pyro ninja Yeh money is not that big of a problem. So ill go for brass, and that picture is almost exact to what i want, except ill have a small chamber going under like in my paint drawing. I Wont this to be VERY powerful. What type of trigger did experament_u2 use in that cannon? And a rubber ...

Fair enough, 400FPS is good enough for me.

Just need to get a QEV, they have them on ebay by anychance?

Hey guys, i'm starting to get back into the spud gunning :roll: My plans are to build a Pneumatic inside of a Sterling rifle stock. I want it to be all metal, now here comes the questions: Does the paint design show any flaws? I've never made a piston, but theres always a first time for everything, ...

Hey, I cant upgrade to metal, it will remain Pressure PVC. Im using a sprinkler valve, actuated by a blow gun. I'd say my barel is excellent, marbles fit with about 1mm gap. Ok pics are up. I Think im going to keep the chamber the same size but maybe decrease barrel length to... hmmm lets say 50-60c...

Hey guys, i know i havent been around in a long time, i've just been so busy. I've finaly decided to add those finishing touches to my marble gun.

Might have got the name wrong but eh.

I beleive it is not pressure rated, as i once read on a topic, how to tell the difference. LOOK at the pictures he posted, where the smaller side of the bell reducer connects to the pressure side of the sprinkler the valve, the socket is like 1cm deep. but lets not cause a huge debate about it. Hes ...
