I cut it from round stock with a band saw.

What works best is whatever works best to keep as much counter 
bearing angle at the "capo" as possible, and still get enough 
angle at the brass insert that it won't buzz. As I said, I 
don't have numbers. I experimented until I had something I 
liked. Clamp or screw one each of the two types of termination 
pieces to a plank, and play with string and  wooden dowels of 
various sizes until you find something that works. Then 
reproduce the dowel in brass.
