Hi Ed and all
Not seen that effect but no doubt it occurs with rotors to a very small
degree.
As the expansion is transverse and the electrodes are axial in designs that
use insulating rotors the effect does not impact electrode spacing.

I think Terry's comments re plastic hubs softening should be considered
carfully if using my initial technique of brass rod with brazed tungsten
tips.
