This angle seems to be a rare bit of info....

I visited one of the local Amish earlier. His friend uses
an OLD New
Idea that had this style clutch on it so I drove over and
took a closer
look. His has some wear but it measured at just a touch
under 32
degrees. I would say new they were probably 30 even and
have worn in a bit.

My guess is that the original angle was 30 degrees. For any
amount of
torque , any angle will work as long as the spring rate is
right for
that angle. If you had two flat disks, that would work with
enough
force pushing them together. So the designer probably
choose an easy
angle to cut with tools that are easily bought.

Great news guys! Thanks for looking into it, eih? So it is
30 deg then.
