Some of you guys (Bubba, Me2, McGyver, HuFlungDung, One of Many, ESjaavik, RotarySMP, and Bluesman) gave me valuable advice in the early stages of fabrication, so thanks. Incidentally, I was never able to cut anything, not even Delrin, with that parting tool.

This design is an Alpha style Stirling that is adapted from designs by this guy:

...Although I have no idea how he carried out some of the operations he mentions only in passing, like glueing the syringe barrels into the chassis. The only way I could do this without ruining the barrel involved adding machining steps.


I've put together some footage of it running:

Thanks again!
