Our new behemoth-of-a-cannon

Unread postAuthor: LynyrdSkynyrd » Thu Jun 12, 2008 11:40 am

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

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

This is bacically what we got going on:

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.
