I thought Jument would be a cool name. Look it up.
Cannon Specs.:
All pipe is sch. 40, everything is NSF-pw, no DWV. I don't want to kill myself.
2 3' 3" chambers
2" pneumatically actuated sprinkler valve (3/8" ball valve for actuation)
Interchangeable 2.5" tennis ball barrel and 1.5" potato and other crap barrel
A wicked paint job, If I do say so myself . . .
2 shrader valves for filling (bike pumps all the way!)
I normally operate it at around 70 psi, although I know I could definitely go up to around 115. 70 psi with bike pumps when you have around 7 to 8 square feet of chamber gets tiring after the 3rd or 4th shot.
This thing is so much fun! A great mix of power and portability, and pretty dang intimidating.
The paint on the 2.5" barrel seems to be chipping off (Although the 1.5" one seems fine . . . odd) so I'll probably sand and repaint it.
I've left the solenoid on just to plug the hole, might do it with some epoxy later.
I might post some damage pics, but its hard to capture the feeling of little chunks of potato raining down on you for 10 seconds after a shot at a piece of plywood 45 degrees to the ground.
