Before I really got involved with FRC too much we had actually built two different potatoes cannons that used air pressure. We were doing a very similar design only difference was that our barrel actually went down through the air tank but we were easily pushing 100 + psi into the 4 inch air tank with no long term issues. Again though we were always careful to make sure that we were using at a very minimum schedule 40 PVC and in most cases used SCH60 pvc so that we would have at least a 3x safety factor on our intended PSI and the max we could do.

So what also has me extremely curious is how do you fold/roll the Tshirts so that they come out of the barrel and stay somewhat together on the way to there intended target and not just unfold and act like a big sail/parachute and come right down to the ground?
