|======/ |===rotor===| \======|
I hope you understand. The upper startor plates are closer to each other by about 0.2mm. This means that the top rotor plates will be closer to the startor piece than the bottom ones. This is not good and I have to figure out how to deal with it, because they cant do the lathe work if the startor isn't right and they do not have the equipment to fix the startor. I already have some thoughts, but this will take time.

Jetijs,
The machining operation to fix your stator piece involves clamping it in a vise between two large blocks of aluminum for extra support, and then using a vertical mill with a boring head in it. The diameter of the cut can be dialed out slowly .0005" at a time. Extremely precise corrections can be made.
Support the stator pieces as much as possible because the milling operation is an "interrupted cut." The set-up is the most difficult. Mounting the stator piece in the vice and then finding the exact center to begin the milling operation. The actual cut should take about 5 minutes. The set-up may take an hour.
Too bad more care was not taken in the gluing operation.
(Aaron should be getting those pictures posted soon.)
