Hi All:

     For HV design the toroid is much more flexible than the sphere.  May I
suggest an alternative design possibility?  Use two large toroids spaced
apart.  A hole in the lower toroid provides entry into the shielded space
between the two large toroids.  The hole in the lower toroid is encoumpassed
by a small reverse toroid as has been mentioned before.  The small reverse
toroid can be made with the two halves of one of John Freau's toroids
clamped, copper taped, conducting glued, etc., over the hole.  The center of
the small toroid shells can be cut out with a simple band saw by laying them
on their flat sides.  The transition can be smoothed with copper tape.  The
two big toroids can be held apart with three tapped metal rods,  pipe
sections from the hardware store (small flange on one side, sawed off
coupler on the other side maybe?), or threaded rods covered with straight
sections of metal tubing, or a sheet of aluminum all the way around the
inside of the toroids.  Adding more capacitance is simple.
