My first air cannon
Posted: Fri Dec 04, 2009 9:56 pm
this is my first air cannon that I have made. I have had it for about 4 months but just recently found this site, so i figured I'd post up some pictures.
the chamber is 15in long and 3in diameter. The barrel is 30 inches long with and 1 1/2in diameter. resulting in a 2:1 chamber:barrel ratio.
the psi it run it at anywhere from 120-140psi
I do not know what the full distance potential is because I do not have aerodynamic projectiles and no way to measure the distance it fires.
the projectiles I use are usually made of ice. I do this by gathering up slushy snow, putting it in a length of 1 1/2 pvc and then put a 1 liter mountain dew cap (which conveniently is the perfect size to fit snugly) inside the pvc on top of the snow use a ramrod and hammer to compact the snow as tightly as possible, then I remove the almost solid ice core and place it in the freezer, wait about 5 min and tada projectile that leaves no liter, or trace, so I don't have to go around picking up after myself.
additionally I have several other barrels as seen below.
Anyways if you read this far thanks for sticking around I know I can be long winded at times. and if you have suggestions for how to improve it i would appreciate it, at the moment im thinking about a sprinkler valve and piston valve setup. thanks
