The problem with a fixed cutter is that the shape of a pulley is
dependant on it's diameter. as you get larger or smaller, the angles
and radius's change to accomodate the OD.

It would appear that one would need one cutter for each diameter.

Another option might be to mill the part ? Just use a tool that has a
length greater than the pulley width.

Trapezoidal are harder than round. for round cogs, you can drill them
and then turn the OD of the part.

What i have done in the past is to turn a shoulder on the shaft and
then bore a pulley to slide up to the shoulder and then bolt the parts
together. Works great with larger pulleys.
