water cannon

Unread postAuthor: xboxteen01 » Wed Jun 11, 2008 4:21 pm

so since summer time is around ive started shooting water out of my pneumatic gun. since the water basically mists after 15 feet, i thought of a way to make a nozzle. i havent seen it before on this site and heck, it may not work but here goes.
For a 2" barrel, secure a 2" female thread piece to the muzzle. then use a 2" cap, the dome kind, and drill a hole in the end, say 1/4" to 1/2" size. use as small a piece of 2" pipe as possible and mate a 2" male threaded piece with the end piece. after its cured, pressurize the gun, fill the barrel with water and screw on the nozzle. ill try and build and test this weekend, but leave feedback and criticism.

Sounds like it might work, but you don't need anything better than a ballvalve. Check out the water gun I'm making atm - should be good http://forums.sscentral.org/t5053/

there is a better way. take a bunch of drinking straws and glue them together side by side, enough to fill your barrel, then fill(just the end) with them, Im not sure how it works, but it does, it will keep the water in a stream, its what disney uses at its parks for the "jumping water".
