I have a LOT to do on this machine, the ratchet wheel is near the end,
I'm just thinking ahead.

I can imagine placing a plate on the table of the mill, with some pins
that locate the center hole of the wheel. Then, you cut the first
tooth on the mill, and then rotate and clamp the wheel, and a pin
or some other locating device indexes the first tooth. The
alignment of this index pin is pretty critical, but maybe with careful
measurement, you can set it up so you don't have an accumulated error
when you get to the last tooth. The plate would hang out the front of
the table a bit so the back of the wheel would clear the mill's
column.
