My homemade scuba tank air cannon that i built myself. I build a new cannon now so pics come when it are finished.
Some facts: The tank i got from my dad. i shoot 60 meters with 1 bar. I don't know what pressure welds can withstand so I fill the tank with very little air.
AND IT'S NOT TAPED ALL THE WAY,IT ARE FITTINGS THAT HOLDS EVERYTHING TOGHETER

because its a steel tank designed for pressures up-to 6000psi and when you weld both the rod and the steel from the tank melt together people have plastic penguns made with pen and epoxy and they can withstand 400psi

i agree with Technician1002 fill it with water and pressurize it to about as high as you can go and if it leaks, weld over it ;D
