I have a question about ball valves: does anyone know a way to attach a lever to it to make it easier to open? If so please reply.

i have used it up to 65 psi multiple times with no problems, should that be my maximum, or would it be safe to hit 75 psi? Also i do not know if it is nsf-dwv, if there is a way to check i would like to know.

most of my ammo is duct tape wrapped projectiles, my most successful piece of ammo is duct tape wrapped golf balls.

I would say it wieghs in anywhere from 20-30, but that is just a guess. It is not to hard to handle considering that you shoulder it.

9 Foot Long Pneumatic Cannon

This is my second pneumatic cannon. It has a ball valve trigger system. The expansion chamber is 4' long and 4'' in diameter. I fill it with a schraeder valve. There are two inter changeable barrels, they are both 4' long and one is 2'' in diameter and the other is 1.5''. I typically shoot at 65 psi...

I just filled the above cannon to forty psi, is 40 psi too much or can I fill this up even more? I don't want my gun to break but if I can crank it up even more it would be unbelievable.

Caulk??

Will Caulking around the fittings of my pneumatic potato cannon make it any more air tight and safe. I haven't done it yet I was just curious.

I over pressurized my pneumatic potato cannon and it was my first one so I did not know how much glue to use BOOM the back flew off. It was a quick fix i just used more glue this time around and it works fine!
