If one has an old metal shaper one can also make a carbide cutter for gear teeth for the clapper. Course shappers only cut on the forward stroke so...dead simple tooling...but you pay for it in 40% more cutting time.

It sounds like an interesting read.

I've cut a few gears using a hand ground fly cutter also.
