Unread postAuthor: jrrdw » Thu Jun 15, 2006 5:54 am

I'm planing to build my pneumatic cannon like this - useing old Emglo aircompressor tank's, (7" dia. 3' long) 2" outlets, into 4 way barrel sealing piston valve, adapt 3" 15' to 20' long barrel, adapter will work as ammo stop.

What do you guy's think of my desighn?

It sounds insane... impossible, improbably undo-able and I'm just writing this BS for no reason...

That sounds like it's going to hellaciously cool when it done....

Lol, it wont be to hard...

just a 3" cross with 3" to 2" bushings on opposite sides... 2" elbows goint to tanks.... 3" Female on the barrel end and 3" cap on the pilot side...
2" Cap with rubber for the piston....

That accually sounds really cool.... your probably goings to have to make the side with the piston extend some so when u let the pilot go the piston has room to slam back into...

So basically it's 2 barrel-sealing valves combined. This design wwas posted on http://www.air-power.net a while back. Nice thinking though.
