Hi!
An other side-side-project (note, that the nesting level is reduced) is this little aerial 3 cylinder radial compressed air engine. While working on a side-project, I realized that I could recycle these cylinders. The other ones were more complicated, so I removed that portion of the code and cut down the machining time for one cylinder to less than 5 minutes.
Only thing missing was all the rest around the cylinders.
Many years ago, I already had built a similar engine that I liked a lot. So I already had a vision how it had to look like.
I wanted to make the case as a casting. So I have drawn one and almost wanted to start milling the pattern. But sleeping over it, I had a way better idea when I woke up. Threw the whole work away and started new.
That's how it looks like:
Now, it is almost 3 o'clock in the morning here and I have assembled two more variants:
A different color to the left, and a bare metal one (just tumbled) in the middle.
I have more pictures for you to come, but you'll have to wait 'till Monday. I'll leave for a vintage motorcycle fair this morning.
I intend to publish the plans, but I do have to draw them first. My sketches aren't any help for anybody except me.
And here is a machining video of the case:
