Nice work Chris. Would you mind elaborating on how you formed those ball ends?Jim

I don't have a ball turner gizmo for the lathe, so they were just hand turned on the ends, by eye, then cleaned up and faired in with a flat file while spinning. The file makes it easy to take off high spots and get a good curve. They are not ball bearing perfect, but close enough to work. The arc continues back past center to the start of the flat end. I know some here will yell at me for filing on the lathe, but it is well away from the chuck, using just the middle of the file on an outside curve so no risk of catching the file.

One of these days I want to get set up with a tool rest and some gravers to try some turning.
Just fascinating work, Chris. Kim
Looking great Chris I'm always amazed how you manage to machine large components on relatively small tooling.
Hmmm.... That needs some sort of saying, how about, with enough small bites a mouse can eat an elephant!

You give me positive inspiration I keep pondering how big a steam engine I can realistically build on my 10x22 lathe and bench mill, I really want to make something that can do some proper work and won't be satisfied till I've build it
