I miss my old potato gun. I left it at a friend's house years ago and never got it back.
I made the barrel like 6' long, 2" diameter, then the gas chamber was like 4" diameter. Had a nice 45 elbow for a handgrip/trigger. Used an old grill ignitor. Worked pretty well. I found that Aussie hairspray or Right Guard deodorant spray were the best propellants to use (either or, not at the same time lol).
I should build a new one.
