we drilled a hole, put the valve stem in from the inside, then siliconed the outside. we even put a psi gauge on it. I wish i had a pic. Maybe I will make another this weekend.

we used extra PVC pipe we had layin around. it was like 2/1/2 i think . we bought a valve, gauge, valve stem and lots of silcone for like 15 bucks. everywhere 2 pipes connect, it was sealed with a bead of silicone. the valve stem like I said before was drilled and inserted from the inside then siliconed on the outside to hold it and seal it. the gauge, it was also siliconed on the outside. we put an elbow on the end so it wouldn't be as long, and it would hide on the floorboard of the car.
you get the idea......
one tip, we had problems opening the valve with the air in the tank, so we put an adjustable wrench on it for leverage. (anything could be used)

hey what kinda valve did u use to hold that much psi? like a butterfly type or what?

Im not really to sure...and I dont really even think we took it into consideration. We just built it, and started filling it. It was a huge frickin valve though.--i think it was a butterfly. On the side of all PVC it says in blue lettering how much PSI's it will hold.
That potato gun was bad *** though. Cause when you make one with an ignitor you never know when its gonna go, you just keep clickin... With air, you know its gonna launch.

we just used it for braggin rights. it was so insane though. we would break out windows (3 cars bumper to bumper, an apple would go through all 3 cars- windsheild and back window) and a mail box, no match. (ever go mailbox smashin) I think i might make another this weekend. I am thinkin of making a go-cart though.
