Thanks Johan. That's a great idea about the gel and toothpick.
I'm feeling less down on this today and will share a few more details. To repair the gear adjacent to the center drive gear, I put the pair of connected gears in a 5C collet on my lathe. Then I cut down the larger of the two gears, which had a broken tooth, until the OD of the old gear was 0.105".
I drilled a 0.105" hole in the middle of the new gear and slid it onto the old gear and secured it with a bit of superglue. This picture below isn't the best, but it shows the result. I later put the gear in my ultrasonic cleaner and it looked much nicer, but I didn't snap a picture.
I was feeling pretty good at this point. However, after getting super glue on the gear, and subsequently breaking one of the teeth on the above gear, I lost the wind in my sail. I think I screwed up the center drive gear too.
I think, also, that while I understood what needed to be done, I was lacking the experience to do it cleanly. I learned something about technique during the process and know how to do it better the next time. I'm going to give it a break for a few days and then regroup.
Is there any reason not to replace the center drive gear and the gear pair in the above photo with brass gears? They're only E1.90/gear more from kkpmo, or E5.70 for the three gears. I would feel more confident working with the brass gears, for some reason. I may even ask kkpmo if they have the capability to make me the gear pair in the above photo.
Cheers and Merry Christmas!
