1/2 Scale Stirling Cycle Fan Engine
I wanted to build a low temperature stirling that could run on waste heat from my computer monitor, but I was advised to start with one of these. It was a challenge to get he friction levels low enough for the engine to run good. The parts were smaller than I had previously made and were a challenge. The most fascinating ting is when you try to start it the first time, light the lamp, wait and give it a spin, one way starts getting easy and the other just stops, suddenly it just silently continues to operate. I highly recommend a stirling like this one to a new engine builder to learn about friction in model engines. Operates for over an hour on a jar of alcohol.
Jerry Howell sells plans and hard to find parts for this and a number of different stirling cycle engines and internal combustion engines from the simple to complex http://www.jerry-howell.com/ .
