It sure would be nice to know this angle just for curiousity

shipfitters wedge and it's angle is 11 deg. It will not slip

application, eih?
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.
