Dr., when you say "base of the toroid," do you mean the lowest part 
of the toroid (which would be the underside of the cord) or the disc 
in the center of the toroid?   Dennis

With magnet wire coils I usually space the base of the toroid 
(horizontal plane) 3 inches above the last secondary winding.

With large PVC covered insulation on the wire, I usually set this 
distance at 6 inches.

The larger the cross section of the torus the more height the coil 
will tolerate --- increased electrostatic shielding of the upper sec turns.
