A customer contacted me recently and asked if I could roughly match a Vise screw hub he had seen. The only issue was that the two screws were very different in size.
The results weren’t too bad!. One will be used in a tail vise, the larger is going in a leg vise.
The larger of the screws is a standard 18″ screw, with an internal garter slot added and the hub customized.
The second screw is 1 3/4″, with 3 tpi, at 13″ long. The garter slot will have an external garter.
