A gentleman I know is rebuilding a 1923 Model T Ford, and needs the commutator on his generator turned.

PM me if you can help.

Thanks!

Well, I'm in Canandaigua, and have a small lathe. Doing a commutator properly (and I don't know much about it) also requires undercutting the mica or whatever they used for an insulator. There are/were accessories for that, but I don't have such. If he can describe exactly what he wants done, I might be able to help. OTOH, going to a specialty place that does generators for a living might be a smarter option.

For reference, when I was young, there were no alternators. So generator repair was very common.
I have seen homemade jigs to turn a commutator on the car, they clamped to the gen shell.
To undercut mica, which has to be done after turning, it was common to use a hacksaw blade. You ground off the set on each side of the blade so the teeth were there but no clearance angles. Then you hand dragged it in the slot between bars to remove mica, usually to about .030 thou depth.
