Very simple cannon
diagram is pretty much all you need to figure it out.
It uses a 3/4" cap as a piston. |

| You're asking for a barrel collapse if you use thin-walled pipe, but other than that it looks al right. You should try sleeving it in some SCH 80 1." |

the barrel would have been 1/2 sdr 13.5 for paintballs. It is actually rated for 200 psi. I've used it in one coaxial already and it holds up fine.
I decided though to use 1/2 CPVC instead for larger chamber volume.
Basically you just pour in some airsoft bbs and plug it with a circle of cardboard so the bbs stay in while you arent shooting. When one guy has you pinned down on the airsoft field, just pull the pin and shower some bbs on him! |

| Better chrono it first. I brought my PB rifle to a field and the guys said I could use it if it passed the speed test. It shot 455 fps at 40 psi. You shoot someone with 50 airsoft BBs at around that speed and people aren't going to be happy. |

| If you can't figure out how to do it, you shouldn't be building them. |

| It uses a barrel sealing diaphragm. You can see the actual finished gun here. |

| well say a 125psi pop off could be used on a boiler or something and incase something went wrong and the pressure built up to 150psi i9nstead of 100psi the valve would release pressure until it comes back under 125 |
