it's 12 dollars and you can buy multi boxes like that at stores so there's no S&H. and that's better than a bulky air tank

air you loose from the pop-off is wasted,and with a pressure gauge you can go to higher pressures then previosly desired as the pop-off cant change its set pressure without you modding the spring.
and remeber to get a decent amount of air and pressure youll need a pretty big tank to lug around with you,i understand what your saying but if you use sch80 you wont need a pop-off just a gauge and you can always slow the air down with a coiled hose or a small dia ball valve or even a big valve just open it slower or only half way.

So you're saying I wouldn't need a pop-safety. Hmmm...

How small of a valve would I need to slow down the air a lot? 1/4"?

well say if you had C1 mounted on your back to connect it to C2 you could use a 1/4" coiled hose so it slows it down and then a 1/4" or 1/2" ball valve.

Where can I get coiled hose and would it be slow enough for a 0-5 PSI margin of error?

you can get coiled garden hoses and some are rated up to 200psi and are about 6m long when full stretched,not sure about that margin of error though.

im gonna go with "not safe" on that. just use a steel chamber, smaller and just as good. plus you can control the volume of c02 by adding some lenght to your pipe. or maybe open up a pb gun and see how its done. or hell, just use the line as the chamber, ur shootin stuff like paintballs, so the tiny amount in the coiled hose might even be enuff. but i wouldnt trust pvc and a ball valve to regulate it. accidentally drop ur valve and BOOM.

thats why im saying if your gonna go over 200psi metal is the way to go and you can get some ball valves rated that high.

Well I'm not going that high C1 is going to be 150 PSI at most w/ PVC not metal. And KVINCEO, I'm not using CO2 with this cannon.

Could I use the hoses used to connect blowguns to sprinkler valves? I think they're pressure rated but I'm not sure.
