Just got it firing!
Does anyone know what material is used for main bearings?

Correct.What for / do you intend to machine it yourself ?
Howdy, I could assume it is some grade of babbit or other Al based alloy of which there appears to be many. Difficult to see how you could botch a job like that.I bought an Eldo Loop in the 80's that the PO had tried to put in an insert, it did not work. I tossed it & replaced w/new factory part. You will end up spending more $ than buying a new factory part.
The material is same as a car engine w/plain bearings.
Good call then.I didn't like the way it looked. If I build a motor it's guaranteed, if I don't like the part I don't use it. The PO didn't know any info on it, friend of his made it.
I don't know what "main( bearing)" is, but I believe no manufacturer uses non standard bearings, those days. So should you, I'd say:
- I can't see any good reason why you should resign to machining one bearing yourself.
As (I hope I caught that) you wrote, machining an adaptor - as a "Z" plan - is someting much easier.
Probably I've been missing something ...
