## 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.
- Purchase - Great pricing - Fast shipping - A vendor I have used in the past and will again in the future.
- Worm - Haven't used them yet, but they match the worm gear perfectly. They should serve the purpose for which I purchased them.
- Speed reducer purchase - The purchase was easy it did take two purchase until we got the correct part I guess it was a fault on both parts as we were looking at the wrong part number, but overall the purchase was good part fit perfectly. Thanks for your support.
