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.

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

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 ...

25 shots for 20$? No thanks. I dunno about you, but I'd rather have 25 shots for free. And yeah, that is expensive when 1 12g=1 shot and I don't have a job.

OK I'll try one more time to explain it. C1=high pressure (150 PSI (PVC)); C2=low pressure (30-50 PSI). C1 > C2. This way C2 can be charged multiple times from one charge of C1.

The point of this setup is to NOT USE C02 to get many charges because CO2 is expensive.

The pop-safety valve may open ...

why dont you just use a gauge instead, the small chamber could hold 125psi and when it says that on the gauge you just turn the ball valve of.

While a gauge should be on the small chamber (and the big chamber), the pop-safety valve needs to be there also. The small chamber should fill up very ...

Sh*t. Before anyone says anything I'd like to say that this idea is 101% original. This topic is, however, similar to a recent topic by THEMOST.

OK, I guess I was wrong when I said self-explanitory! I'll edit my original post right now and post directions of how it works.

I'll post a simple flash animation later or tomorrow of the whole process. I just made the animation but unfortunately I don't have access to the computer that has it ...

There is no CO2. It's the "solution" to CO2 because it's portable and inexpensive.

I drew it in flash because i have skills in flash and I don't have skills in anything else, and I want to animate it eventually.

This idea hit me a little while ago.

Please give me your feedback.

EDIT: This is how it works: The ball valve is closed and the high-pressure chamber (C1) is pressurized using the Schrader valve. (Ideally this chamber would be made out of metal to withstand extremely high pressures, but it would ...

I have a CP-100.

OK thanks I'll try that tomorrow and get back to you. I've had enough aggravation from this mini for one day.

Yeah I've tried that. Do I do that after I spray the Tag in or before? I've done that after and it didn't work.

I'm starting to think that condensation could be the issue. Should I wipe the chamber out after every shot?

My simple mini combustion isn't working properly. It consists of:

1 Film Canister as the chamber
1 Film Canister lid and pen tube (connected) as the barrel
2 Nails for spark jumping
1 Piezo for spark

The peizo is attached to the nails via wires and alligator clips (heat sinks).
The peizo sparks ...

Awesome, thanks a lot guys.

You can expect to see my Dragunov paintball sniper up here soon.
