I just brought home a 10" Logan lathe, seems to be in a reasonably good condition except for the multiple teeth missing from the bull gear. Can't find anything used right now, and don't need the low speeds badly enough to pay for a new one. How rare are these? I've seen many stories of people replacing individual teeth in a variety of ways, but I'm missing 8 of them and not sure it would be worth the time. I thought of turning all the teeth off the gear and replacing them with a ring gear if I could find the right size ring, or donor gear to make one from, but haven't been able to find either. Has anyone else ever tried this approach?
