The rotor disc is precision drilled and then precision reamed to a small
tolerance -- then the tungsten electrodes and pressed in place (using a
commercial hydraulic press). The hole location also has to be very exact
to keep the spinning rotor properly balanced. Don't try to do this
yourself -- take it to a good machine shop along with your tungsten rod --
they can measure both and get a correct fit. They also use a rotary
turntable to precision locate the holes for drilling -- accuracy is on the
order of 1/000th inch or better -- definitely not a job for the
do-it-yourselfer. It's important these procedures are done correctly so
the rotor doesn't blow up and hurt someone.
