Ditto on Deves article.
If the ring gear has a heavy chamfer you still can usually still repair it by turning it on the flywheel. If you notice a spot that is worn far more than the rest of the gear it is because an engine almost allways stops rotating in the same spot when shut off, this means the starter gear engages the same spot on the flywheel every time you start the engine, so if you rotate the ring gear 90 or 180 or whatever you want, you get a new spot to wear on. Obviously this won't work with a severly abused ring gear.
