A Stirling engine
« on: October 27, 2010, 06:54:38 AM »
Another gamma Stirling. Both strokes are 15 mm, work piston is 12 mm dia graphite, displacer is 17.5 mm dia and the glass cylinder is 18.5 mm inside.

This is what she drinks, no meths, straight stuff...


And here she runs


The flywheels have some balancing, but not enough, she walks around the table somewhat.
The burner tube is too long, the wick stands too high. Have to cut a bit off it, and fix it to a proper board. No polishing yet, just finished it yesterday so it would run. Always nice when a new machine behaves   :)

Beautiful work, that's a classy looking engine.

I hope to emigrate to Portugal in a couple of years time (approx), nice to know where I can get rubbing alcohol :)

Self build? Pictures of the build process? did you follow plans?

Very nice!

Yes, self built, following a German design and plans. I also bought the glass cylinder, the graphite for the piston and 2 ball bearings from Germany. And of course, made some slight design changes... No pictures about the build, sorry. I´m planning to do another bigger machine following the same basic design. I just bought a new camera/camcorder, I hope I can take pictures about that build.

Where can one find the plans?
