Jerry BlandAngle of teeth on Graham escapement wheel?
I followed Hedrick's design of a 30 tooth deadbeat escapemnt wheel and matching pallet, but the exact angle of teeth or way to figure that was not discussed. I think he meant 15 degrees on one side if tooth and 25 drees on the other, but not sure. Is the exact angle important?
