Making the necessary jigs and fixtures is more work than making the actual parts.
For the primary, I made a new wedge error tester, from an old tooling plate, that allows me to also measure the concentricity of the inner diameter.
For making the dovetail plate, I had to make a fixture for cutting the 60 degree angle of the dovetail.
Next I have to figure out a way of setting up the primary on the lathe to cylindrically grind the inner diameter to the required specs.
