Although a good electrical insulator, Delrin is a poor choice with regard to
heat.  Your electrodes may warm up enough to become loose in the wheel and
start flying out.  G-10 phenolic is more expensive but much safer for
holding rotating electrodes securely.

Slotted delrin is great as a primary coil holder and the black seems to
insulate nearly as good as the white against HV standoff.

Please error on the side of safety.
