I wonder if you couldnt get a machinist to either put two small groves
in a tungsten electrode (or in a sheath heat shrunk around the
electrode) and then secure the electrode to the disk with circle clips
on both sides. This would allow a pin that floated a few thousandths
of an inch side to side until the electrode heated and expanded into a
tight fit. (seems like this would place less compressive stress on the
disk)
