Describe the technique you used for drilling the holes and locating the
holes for the perpendicular electrode holders in the the rotor.
If you didn't use a milling machine equipped with a turntable accurate to
1/1000th inch this is your problem. You absolutely need to have a machine
shop perform these operations. Also, the electrode perpendicular holders
must be machined to a uniform length accurate to 1 mil.
