What nice stories you have, once I had a motorcycle engine on the table in the bedroom. I need some thinking of what I could do with it.

But now the problem are of smaller physical size.
Today I have found shims washers of steel, m40 ID 50 OD, 0.1 and 0.2 mm thickness. I don't trust these plastic shims, the old are deformed by the pressure. It will come photos later. I will keep one plastic shim on top to have it act as a spring when length of shafts changes because of temperature.
I wrote to the university where I studied once, thay had a terrific workshop. But they didn't have it anymore, I must look for a lathe somewhere else.
Everything are in progress now and I can't see any problem that I can't fix.
