I have an old Bandsaw that I’m looking to create a low range gearbox for as I want to convert it from wood to metal cutting. It’s a fun project and gives me an excuse to buy a dividing head for the mill.

I have a 1946 Hercus 9C too and whilst I’m in the making mood I’d like to add metric threading capability to it which requires making a 127/100 gear. So I’d like to confirm what cutters to buy in order to complete both projects.

I’ve seen references to 18DP 20 degree angle.

Is that correct? Is there a way I can measure the existing gears?
