Hello all, I think I've finally got enough parts going to share my progress on James Senft's Moriya Stirling fan. This project rather stalled for a while so I"m thinking posting progress updates will keep me accountable to get parts done.
Some parts I"m making two of, either because they're very easy or because I feel I might mess one up in some way. Feels like less of a setback than starting a part totally over from scratch.
First up is the displacer, made from .040" tubing from an old tent awning. I held it very gently in the collet chuck and bored the ends. On the second one I dared to turn the outside, which resulted in only a little chatter. I probably won't notice it running any different but the second displacer turned out 2 grams lighter than the first.
My first time trepanning anything on a lathe is to relieve some weight from the top cap on the displacer. Takes a lot of relief on the tool for a less than 1" diameter.
And the end result of that part:
