Hello Michael,

At least you know the information exists when you feel you need it. Waltham watch threads are far too fine for me, I am into the machinery itself, jigs and fixtures and so on, with a side order of commission work, in particular screw cutting gearboxes as well as support for Remap, the assistance charity for disabled folk.

The present gearbox is a genuine 115 year old Norton for an equally old American Hendey lathe for a UK collector.

It is only 10 years younger than the very first gearbox that Norton patented. There is much to do, it is a complete wreck with a bent leadscrew as well..

Regards Brian .
