This is our new pneumatic. we built 2 chamber sealing valves w/ 3" porting and 2 approx. 1000 cubic inch tanks.

We also added a recoil system using drawer slides and 2 garage door springs and a gas shock for a crown vic.

More pictures and video to come!

Here it is with a shot of a gallon of water @ 95 psi.

yea, that was our first "heavy" shot, and we didn't have a good camera for some better pictures. So right now we just wanted to kind of put it out there as a preliminary. We'll get a proper post up soon

thank you! like i said its not an attack its a way to get this cannon out there... because i love it.

what did you make the pistons out of? they look quite nice.... almost an hourglass shape (whistle)

the pistons are made out of UHMW and the hourglass shape is just to reduce mass.

This is bacically what we got going on:

except the piston(blue) is an hourglass shape.

WOW.

for a newer member you got your game on..... lol. I think even more than some of the seinor members of this forum.

i think those are the best looking 3in porting piston valves ive ever seen.

ah and they are chamber sealing as well......... (whistles).

Elegant but beastly! I love the piston design and tee porting work. Is there any way we can get some closer views of the design...recoil system etc.
