Just a question
How would one go about fixing a timing gear if the bore is off center to the the OD of the Gear useing a CNC Mill.
Is the entire surface of the bore damaged?

I would say it depends on what you need to work on. The bore or the out side of the gear?

just the bore being off center, It’s a argument I had with a manual machinist, I am just seeing if what I think would work and other ideas.

Assuming its a timing gear for a motor you might be able to braze it and re bore it. Or get a new gear “Change gear” and cut it to suet your needs. You will need to make some kind of fixture to index the gear to locate the key.
It would help if you could draw a pitcher of what you are asking.
Thank you for your time,
wondering why you would have an eccentric gear?? maybe on a cam follower or on the shaft, but a gear??
Depending on how damaged the hole is, and if welding is allowed to begin with on the gear…
you could dial in the hole, bore it oversized, shrink fit a bushing in, weld it, rebore it to size?
