I like to make all my toroids with central conducting plates even though it
doesn't contribute to the capacity much at all.  It does act as a broad flat
contact, and all of my resonator coils are topped with circular, closed
copper rings expoxied to the top lip.  This way I just gravity drop the
toroid on the system for connection with no bolts.
