I did something like this with a shaft that someone had put some
brazing on.

It was only 5/8" and looked a bit like a sausage.

Had to grind the two spots where the bearings were to go.

When I was done, it still looked like a sausage, but the bearings were
concentric. :-)


I don't think 1-1/2" should warp (much). Especially if you don't
put too much heat into it.

Maybe spot weld around then...

The usual approach. Try it and see.

I'll go ahead with a test piece I think and by this weekend my choices
will be more clear.

Has anyone had success with a shaft weldment as an alternative to
machining from stock?

Thanks guys.
