This page features a paintball minigun that I was developing...
this is the rear of the barrel assembly of the paintball minigun i'm building. these are the triggers.
side view of the firing section of the barrel assembly.
this is me about to test 1200psi of CO2 pressure.... No paint yet, just testing the air system.
Just a little note here: the 1200psi doesn't actually get to the paintball, it only supplies the system with air. The guns themselves use a low volume/high pressure to shoot the balls. This type of gun has a mechanism that strikes a 'firing pin' like device which then vents a small amount of air into the chamber. The pressure the ball feels is probably equal to a normal paintball gun. The speed of the balls was under 280 fps when I tested individual barrels one at a time without rotation. As for the '1200' , I didn't trust the off the shelf pressure gauges so I simply noted what they read and then could compare the next test of the gun if it read something different. I was using CO2 which I thought stored at 900-1000psi. If something broke or misfired I would have had some information about the pressure the test was done with.

Look out!!!! It works pretty well, but the steel firing mechanism wasn't hardened yet so the triggers and the bolt began to wear down and have to be retooled and hardened before the next test. When I figure out how to load quicktime movies onto this site, you'll love it.
It starts out fine but near the end you can hear only 3 out of the 6 barrels firing. The catches on the other three wore down and wouldn't release.
