Unread postAuthor: unisonmind » Sat Feb 10, 2007 1:00 am

so this is try #2 with a pneumatic . the camber is a welding tank,a 3/4 Q.E.V. , a blowgun for the pilot and some ball valves for safety.i only got up to 100 psi today cuz my air compressor is down and out so i had to use a bike pump but even at 100 psi it has some kick. ill try to get some damage pics soon. so everyone tell me what you think

Right now I'm having amnesia and deja vu at the same time. I think I've forgotten this before.

Great gun, can't wait to see the damage that thing does. It looks like it would weigh a lot having a welding tank as a chamber.

If you are going to bring that thing over 100 PSI, replace that blowgun valve with a 1/4 inch ball valve.........

VERRY nice gun for a second mate. thats really impressive. wen you put more pressure in put a ball valve instead of a blowgun it will increase performance. luv to see sum damage pics aswell if you have gotten any.

NICE WORK
