IronGoober | Mini Stirling- JB weld piston @IronGoober | Uploaded 16 years ago | Updated 1 hour ago
I made this engine using a JB weld piston in a 1/4" brass tube cylinder. All bushings are 1/16" brass tubing glued with JB weld onto the wires. The wires are all .032" music wire, except the displacer rod. It was taken from a Otona no kagaku engine, as well as the displacer gland. The regenerator is just some foam from a watch case. The bearing for the prop is very small short pieces of 1/16" tubing. This was a fun project and is probably my favorite LTD engine. The video is cut short because the engine unceremoniously toppled off of the jar after shaking itself too much...but nothing broke(thankfully). I plan on making a stand out of a computer heat sink that the cold side will sit on upside down, and then a dome over the hot side to run on solar energy. The dome will act like a small greenhouse/insulation, so it will get hotter than just sitting in the sun alone. I'll post it if I ever get it done.
