Machining for fun: Stirshurst engine

[Norppu]

So I gave it a name, Stirshurst engine. It is simply a combination of a stirling and wimshurst engines. There is no practical use for it but it will be a lot of fun to make and hopefully I also learn new skills on the way.
This all becomes a video series and I will update this thread whenever there is a new episode available.
The first episode is already there.

The second episode deals with the connecting rods
