I am thinking you are talking elliptical
Turning.
That is completely different from oval shaped.
Cnc mill is the way to go.
All you need is a cnc mill (or tracer with templates) endmills slitting saw and radius cutter.

Re: Three inch per foot Case Traction Engine.
I really don't know the exact scale or size of this engine. It could be a Terning quarter size the Anders engine. It does have a Bell commercial boiler probably never steamed. The water pump I'd not plummed and water gage and dome plumbing need replacement. Needs cleanup and painting and bunkers bui...

Re: Bifocal safety glasses
I get mechanic's glasses with the center for distance an magnifying area top and bottom on the lens.
It sure helps looking up at a boring head with those tiny lines.

Re: Nylatron Bushing Use
Nylatron has a large coefficient of expansion from heat. I used it for the slide block on a half size Case traction engine.. Under load the engine would tend to bind up. The nylatron block was expanding in the slot. Replacing that with brass eliminated the problem. Nylatron may be ok for light loads...

Re: Crank Pin Material
I would just use 1045 and finish to size in one setup.

Re: Three inch per foot Case Traction Engine.
I believe the half scale Terning casting kits went to Florida, and the quarter scale went to his son Aaron Terning.
He may still be in Kansas.
I met Tom at Rough and Tumble in Lancaster.
He was teaching some course.
Don't remember the particulars. That's been 30 years ago.
