More nice looking parts Plani. I am anxious to see things start going together and then running of course.

Thank you Tim and Bill  :cheers:

Bill, I'm anxious too. These Stirling engines tend to have some "personality" and sometimes it's hard to get them to run. Although on this one I'm pretty confident since it's a proven design to which I made only minor changes  :). So we shall see.....

I went on with the bell crank.
Some aluminum stock was milled to thickness:


Then the 3 holes were drilled and the piece was bolted down using some allen screws to mill the outer contour:


In the same setup the relief for the web was milled:


Since the holes are symmetric and only the contour of the web is uneven the same arrangement could be used to mill the relief on the second side:


Finished part:
