Shouldn’t be too difficult to mount in the 4-jaw to indicate it in true to center off the remaining good surface, then center drill for a true center. Weld build-up and machine to size referencing center drill bore.
I need to acquire more tools and know how.
Only indicator I have with a small enough tip that might pick up what very little is left of the “good” portion of the shaft does not fit any of the holders I have.
I will get there, I dont have a lot of time to get on the lathe and now the cold has set in ( un heated work area) . Honestly I think I have no more than 15 hours on the lathe for 2023.
