## Product's reviews:
- Boston gear order - MRO had the items that I needed. I ordered them and they were shipped faster than I expected. It was a pleasant experience all around.
- Shaft output is reversible - Description should say that shaft is reversible. Other than that perfect fit. Good communication from the shipping folks.
- 80 tooth change gear - Exact part for the machine, deliverd quickly, and priced right!
- 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.
