People have made unregulated co2 guns before. Most smaller sch40 steel should handle it with no problem. You might have to shop around for ball valves, though. The 1/2 inch ball valves I have are rated to 500 psi, so exceeding that could cause leaks. Just guessing though.

The thing is that i just ...

You do realize that if i did that i would end up pressurizing the chamber to over 700PSI.

wow........ that evil detonator regulator might be in my hands soon. i like the prospect of that. why spend 100 bucks when you can spend 30? just gotta watch out, its lowest output pressure is 100 PSI........... nothing a second reg cant handle.

I like this idea. Where can i get one of these?

The smallest you are going to find is a 45ci tank.

sprinkler valves are only 20 dollars and the tutorial on how to mod them is very easy to follow

i think that u will have to buy the other regulator first to see what kind of output it has and then u can see what u need for your cannon

but im not the god of pneumatic cannons so dont take my word ...

Ok, before anyone gets pissed, I searched and just got confused.

My dad accidentally destroyed my last cannon and I want to build a new one, and he agreed to pay for it.

My question is, what kinda costs am I looking at if i wanna build a cannon using my paintball air tank, and what kinda parts ...
