"So if I got the measurements right the two arcs should be uniform, Time will tell"
Found the error, one index was 0.020 lower than the other. Should of caught it when the already one side cut piece didn't fit exactly into its home Will have to make a new index piece but to test it out I just shimmed it up and cut another. Only takes 20 minutes to do both cuts.
At least I think its right, clamped two 1-2-3 blocks to make a 90, set the piece against it and feeler gauged the gap on the skinny side. Flip piece 180 and feelers give same results. I know feelers are only so good for accuracy but gotta do with what I got.
I see a height gauge in my future . . .
