Hi all-
I want to start out with a gear hob cutter for my hobber that will cut everything FOR the machine itself. The only gear I have right now is the worm gear: https://www.mcmaster.com/catalog/128/1255/
That lists a "Gear Pitch" of 12, PA of 14.5, Gear Pitch Diameter of 1", and OD of 1.17". I have no idea how to convert that to DP though!
Anyone have an idea? Also, perhaps an inexpensive one to get started? Figuring 2" MAX diameter is all this machine could handle. I saw another article for a similar device that claimed it was 20 DP, but I don't know if it used the same worm.
