Hello all,
Apologies if this thread shows up multiple times... I have tried to post it 4 times over the last 10 hours. So if they all pop up at once, my bad.
I have started making chips on the little Stirling engine by Frank Arbeiter in his book "Drehen und Fräsen". You can find it here:

I hope it leads to some one buying the book and building one as well. Other than a few changes to make it suit my taste, it will be very close to the drawings. I will use ball bearings where possible, mine will be air cooled instead of the water resivoir, my material will be whatever I can find on the floor, and the flywheel will be different. It will have a very "De Waal" styled flywheel because I am a fan of Julius' work and I really like the larger diameter flywheels.
It is a very good looking engine with a unique linkage that is fun to watch. I have seen several good runners. Including one built by a friend of mine. You can see it here:
Harry has other videos of this little engine, all worth watching.
The first attached picture is a screenshot of the drawing to show the cutaway and side view of the engine.
The next string of pictures is what little start I've made on this engine. All I had time to do was cube the block. First, I machined 2in square stock down to size on four sides. That should be easy enough. This part is very small, so instead of dragging out an angle plate I used two V blocks in the Kurt vice to face the front and back nice and perpendicular to the sides. As soon as I pulled it out of the vice, I used a sharpie to mark it up clearly because it is not a perfect square.
Thanks for looking, I hope every one enjoys the build.
