0.3 Module Gear Cutting Query
I need to make a replacement fine focus gear for an early '70s Nikon S microscope. The original gear is nylon with a brass hub and it is commonplace for the nylon to split which is what has happened to mine. Spares are no longer available.
The gear has 107 teeth, a pitch diameter of 32.10mm and a 20 degree pressure angle. I have not removed the gear from the scope but photos of others online would suggest a thickness of about 5mm.
I have looked online for cutters and while there are some in the Ukraine, something closer to home or possibly even home made has more appeal.
Would a single point fly cutter be up to the task? Whether I'm up to the task of grinding the cutter is something else. :rolleyes:
