This isn't my first choice. The 4:1 ratio on my dividing head works
great for most normal machining, but I can't get many of the fine
increments often needed for gears and toothed pulleys. I'll have to go
borrow one, and all told, I'm WAY ahead if I can buy parts.

IF however, I had to cut one, I'd use a microscope or other good
magnification, and grind a flycutter to match a pulley of similar size
to what I wanted. I really don't want to go there....
I cut a cast iron gear for a friend's Delta lathe once.
It was fun but a lot of work.
