The PPK-7000
Posted: Fri Aug 12, 2011 7:00 pm
Hey Spudfiles, I've been a member on this website for quite some time now, but I'm just now getting around to building and posting a cannon. I'm so happy with the result of my work. It's taken maybe 2 or 3 months to complete this due to my lack of planning and just building as I was going along . It also took some time to get some parts in the mail. This is my second cannon, but my first advanced one. Both of them are combustion due to my love of explosions .
Here are the specs:
Chamber: 18"x4" Sch40 pressure rated PVC
Barrels: 60" sdr 21 tennis ball barrel and a 72"x2" sch40 PVC barrel
fuel source: 10" propane meter pipe (usually ran at 50-55 psi)
fan: 80mm cpu fan wired to 2 9v batteries and toggle switch
ignition: push button bbq ignitor wired to push button switch
ammo: tennis balls, soda cans, potatoes and whatever else i feel like 8)
I haven't measured its range or muzzle velocity and tennis balls don't due to well for damage pics, but it shoots pretty far. I've been gather info from this site for a while now and I think I put all of it to good use. thanks spudfiles
and here it is! the PPK-7000!
right side of the cannon showing the propane meter and the ball valve
left side of cannon showing the propane tank with regulator and the ignition/fan box
soda can after shooting it at a brick wall. sorry its the best semi-damage pic i could get. I'll try and get more once i find something to shoot at and more destructive ammo.
