I decided to make a potato cannon to quelch my boredom... It was an abstract idea and it ended up working really well.
Introducing the worlds first ultra high pressuure pnumatic potato cannon.
The chamber is made out of high strength carbon steel piping and a 1 1/2 in stainless steel ball valve to handle the 800-1000psi max pressure. Approx volume is 40ci. this will act as a dump chamber.
The barrel is 5 feet of 1.5 in diameter schedule 40 330 psi rated PVC piping. All attached together in a linear fasion. Just like an automag without the bolt.
The valve lever is hooked up to a spring loaded actuator designed to slam open the valve as fast as possible.
The Power Source is a 3000psi air america raptor tank. lasts about 8-10 shots BAH. Going 20 lb co2 soon.
PROBLEMS:
I have to fix my tool shed now cause the POTATO blew a hole through the door. 1/2 inch plywood. Albeit slightly weathered. Potato vaporized.
HORRIBLY innefficent. Should be fixed when I get a bulk co2 tank.
Leaked like a sieve. FIXED heh nothing like 2 bottles of loctite red to seal things together.
Computerized results:
I put the figues through a FPS calculator. Given the weight of the projectile, the pressure of the cannon. The size of the dump chamber the length of the barrel and other such fun figures the computer calculated my muzzle velocity to be over 1200 FPS!!! Yep actually faster than a speeding bullet.
im scared...
