Oops, I think I slipped a groove somewhere. I thought you wrote in
_The Orphaned Engine_ that with a 78mm crank there was no machining
required:

I also thought that "clearancing" was machining work on the inside of
the crankcase to remove material that would otherwise interfere with
the movement of the connecting rods. Or do you mean some other type of
machining?
