I'll post some finished pics later- right now it's black, has a pipe stand and a remote user control box
I swear I can hit the moon with a potato-

anyone else into launching produce at the spped of sound
We just did the basic one with a screwed on end cap. Put the potato into the narrow 1.5 in. inside diameter end, shoot hair spray in the other end. Quickly screw cap on and use a clicker style grill ignitor to cook it off.

that was how I made my first one- then I began improving them over the years
About 8 years ago I once used acetylene in one- knocked my *** on the ground (literally), blew the back cap off into my vinyl siding cracking it and launched the potato to god knows where
The siding is still cracked and that was the last time I ever used acetylene in a spud gun

Instead of "The most interesting man alive", Dos Aquis ought to use you in their commercials as "The most dangerous man alive."
