Jan,
Bob pointed out to me that it may have taken 50 to 100 years to wear in that groove. That being the case, the initial angle was certainly time tested and there would be no reason to change it. I thought of another way to duplicate the angle on a part with a radius on the way to work this morning. After measuring the distance of the old part from the clamp, pull the part out and lay it on a piece of paper. Then carefully trace the outline of the part on to the paper and cut out the tracing. Next, place the tracing on top of the part and slide it back to the place you wish to grind back. Next scribe a line on to the part following the traced angle and grind to the line. Place the reground part back into the clamp at the previously measured distance.
