ALMOST
From Scrap Combustion
My intent here was to make a combustion spud gun entirely from scrap. I ALMOST did it, but I couldn't find a very safe alternative for a barrel.
The chamber was mad from a JIF peanut butter jar and a 2-liter bottle. The 2 liter was heat shrunk over the jar and then a 3x2" reducing coupling, which was attached to a 2" threaded breech loading assembly and a 1-1/2" SCH-40 barrel. Then, the chamber was wrapped in fiberglass resin and mat, and then electrical tape, which I can't get off now.
A chamber fan is set-up and it has lantern igniter ignition. Here are a few pictures:
That's it. Just my own little version of insanity.
