I also looked into getting timing belt sprockets.

I talked to the folks at Ah-ha. They said that the motor shafts they sell
come with a flat spot for a setscrew. (They are Pacific Scientific motors
that are specially made for Ah-ha.)

The sprockets I looked at today from a company called Browning Manufacturing
all had key ways. I think key ways would be better.

I figure that if Ah-ha gets the shafts with flat spots a lot of people must
want them that way for some reason. Would you?

To those with timing belt systems:

How are yours mounted? With keyways or set screws?

Who manufactured them?

Roughly how much did you pay for each sprocket size?

Thanks,
Peter
