Most Powerful FIRST Team created T-Shirt Cannon

[JohnFogarty]

I'm not seeing this happen?? I have a special program protocol I put into my inventor. I have tried 3" Shcedule 40 and 80, with an air pressure simulation. using FIRST regulators and compressors. and the couplings we primed and had machined. The castostophic failure doesnt occur because the REG is INPUT 150psi OUTPUT only 50psi. we must have done almost 300-400 shots last night. Doing the reashearch on how the system we use flows air, the equalibrium is maintained everywhere. The back of the cannon has a dump tank which in a sense also has a quick disconnect. the cannon barrel is the same design used in most launchers never seen to fail..the barrel. Now i CAN SEE NOW THAT THE ACCUMULATORS WE MADE are possibly dangerous 2 1.5 foot long 3 inch pressure rated 370psi capped and primed with..intresingly a air PVC cap. ABS seems to no safer. only one type Air-Line Xtra is...and it's not sold anywhere. I forwarded this to our mentor and he said maybe aluminum, but we have homework to do because dual layered 3in shedule 40 layer with 4in sechudule 40 doesnt rupture unless you are at an air pressure of 1500psi...two of our members made a nailgun with these specifications.
