Thanks for the reply Willie. Without making a dummy I wonder how feasible it is to machine a backplate to fit perfectly. I would think it would be real hard.
If one cut the taper od slightly larger and then face the flat section untill the taper and the flat section blues up.In other words to creep up on the measurement.
Also I would hate to damage the register on the spindle of my emco v13.
I was going to try this from en19 (4140I think) but maybe cast iron would be a better choice simply because its softer.
Does anyone know of any other write ups on how to do this.? I would need as much help as possible.I am a bit mathamatically challenged and the trig to machine a 7 degree and 7 sec and whatever arcs is beyond me.
Thanks Eugene
