I have just a basic tire pump, Im guessing, I'll just use that =)

I love this design, but whats releasing the pressure, ball valve?

Doctore, thanks, Works best in small chambers?

Sorry about the questions but does the shock pump just connect to my tire valve and start pumping?

@ Matty zip, the shock pump looks like a normal bike pump is that what it is?

GUn Freak, I saw a little metal gun on here, I'm guessing 3 foot chamber and was 3/4 inch pipe and the dude was able to put in 300 psi. Which is crazy but cool, Im going to build a metal gun once i find out how to get 300 psi.

For people with air powered cannons, how are you able to get 300 psi or and higher into your guns?

Can you connect a sprinkler valve to a metal gun like this one?

Is it a piston?

I cant braze though, but whats in the back of the tank?

Air Flow maybe?

I have an old propane cyclinder(blow torch type) and wanted to use it as an air chamber and tap the tire valve into the side and connect the sprinkler valve where the original propane head was by tapping it or something, If it doesn't work oh well.

Personally If I were you I'd shoot golf balls they go alot further!! =)

I think you could, I have a golf ball cannon and just have interchangeable barrels, which one is a tennis ball barrel.I didn't change anything and still get great performance
