My most recent pnematic
Posted: Tue Jan 01, 2008 1:20 pm
Well this is my most recently completed cannon and it packs a surprising punch for its size.
The specs
Chamber:3ft of 2in PVC
Barrel:4ft of 1in PVC
Valve:Modified 1in sprinkler valve piloted by a blowgun
I dont now what the muzzle velocity is but Im guessing in the 600-800fps range with specilized ammo.My primaly amunition is hot glue ammo,little peices of a bannana(they fit absolutly perfectly in the pipe) and of course potatoes.I plan to give it exchangeable barrels eventually and maybe modify the blowgun.This is just a very basic pneumatic that I made for 15 bucks(not including the sprinkler valve)but it works well and is my first pnematic that is completly air tight.I will paint it soon and am looking for suggestions on which color I should use.
Here are some pics
