How high will a grease gun go to? I have one of these pumps so maybe it would not be such great idea for everyone, but I could use it. Has anyone tried pressure testing with a power washer?

Hydrostatic pressure testing

I seems that for safety reasons everyone want to know how much pressure fittings can handle. I think I have an affordable method that should work quite well. The hydraulic hand pumps used for porta power hydraulic rams. Most are capable of pressures of up to 1000psi. You can by a pump for about $100...

There is obviously a serious misunderstaning here. The barrel would be 1/2 by 24, I would have a camber of some sort that would hold the co2 pressure. The chamber would be conected to a valve that conects to the barrel and though some method the 12 gram would presurize the chamber.

I think it would make more sense as some sort of claymore mine :) I like the idea of a claymore...much easier to build, and no timing device is required! I have been trying to build a simple airsoft gas grenade for quite some time now, and it has always been the timing mechanism that has stumped me...

Why do you want a highly acurate paint ball gun? I have never thought as paintball guns as highly accurate. Can you increase your air pressure to increase the speed of the round?

Has anyone tried this wih the new small bernsomatic propleyne tanks yet? The tanks are the same diameter as the old mapp and propane tanks but they are only like 5 inces tall. I may convert one for a low volume high pressure tank.

12 gram CO2 questions

How much pressure is contained within a 12 gram c02 canister?

What is the internal volume of a 12 gram co2 canister?

Is there an adapter that can conect one of these canisters to a 1/8" npt or any other npt?
