That’s one hot spud gun. I made one this summer, but it’s nowhere near as powerful as that one.
One word of caution: Make sure no by-the-book police find you playing with it, you’re not supposed to have them here in NH. I got warned for firing mine down in the sandpits near Concord.
I built one when I was 16-ish. It was great fun for a couple of weeks. Then it blew up in my hands. I came way-too-close-for-comfort to losing my right hand. It was black (bruised and useless) for a few weeks after that. Have fun folks, but be smart.
:ahh: ouch! luckily I have never had that problem. potatoe cannons are fun to play with… my mom cant figure out why we are always out of potatoes lol just be careful with them around dogs. mine goes physco when ever it fires lol
In addition to some combustion ones, Ive gotta jumbo pneumatic cannon. Its tank is a 9 foot length of 4" pvc, with a 1.5" barrel contained inside it. It empties that tank- fast- with a custom made piston diaphram valve. I did a muzzle velocity test with the pendulum method and at 60 psi, it shoots a potato at 450 mph. It can shoot em right through 1.5" plywood or split a 2 by 8.
Its pretty fun…but a certain tree in my yard that is missing alot of bark disagrees :yikes:
