## Product's reviews:
- 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.
- Na40 - Fast shipping!!! Great to do business with.
- Purchase - Great pricing - Fast shipping - A vendor I have used in the past and will again in the future.
- Shaft output is reversible - Description should say that shaft is reversible. Other than that perfect fit. Good communication from the shipping folks.
