## Product's reviews:
- 12d.p. 14t spur gear - This item was closer to exactly what I needed than I had thought possible to find in the last 75 or so years. quite affordable, too. I almost didn't look, but when I did, there it was. I had in hand in just a couple of days.
- 80 tooth change gear - Exact part for the machine, deliverd quickly, and priced right!
- Worm - Haven't used them yet, but they match the worm gear perfectly. They should serve the purpose for which I purchased them.
- New lead screw gear. - Used this gear on a new lead screw l made for my old 1919 LeBlond belt drive lathe. It worked great for my application.
