Using a 4500psi 45Cu.In tank?

Is there a way to use a 4500psi paintball tank as the air chamber for a cannon? I was browsing the site and noticed with a QEV it would work but they seem like the volume of air they would put out is only good enough for small projectiles. Maybe im wrong though. :)

You can use it as a primary chamber, but a pin valve has far too little flow to allow the tank to be used as a firing chamber. You would need to drill out the mouth of the cylinder and even then you're limited to 1/2" or so.

What sort of caliber and performance were you aiming for?

That makes sense. Thanks for the info.

I was looking to use a 2 inch barrel to shoot standard issue produce and such. My main thing with the pneumatic I built was the length of time it took to fill the chamber with the compressor I was using. It was a standard 12v cigarette lighter compressor and the chamber is 4"dia by 2.5 feet. Works great with a big shop compressor!
I had thought if there was a way I could use the paintball tank it might be better but now looking at what you said it seems to be terrible idea.

Nothing wrong with using a cheap low pressure reg to fill it up instead of the shítty 12V compressor ;) I would put a safety pop-off on the chamber just in case.

That was my next thought! Thanks for that link and your tips! Oh, and that 12v compressor fried itself after 2 uses leaving me out of commission. Trying to convince the wife I "need" an 8 gallon or so compressor. haha

Ah, marital bliss :)

Surely it's and investment one could slip under the radar at these prices.

This is true. It will show up in the garage in the near future :)
