HV electrodes made up of discrete elements work quite well.
The last spherical electrode I made (out of concentric hoops)
gave a breakout voltage that was a surprisingly large fraction
of that for a smooth, perfect sphere!

I am presently building a larger toroid (28" x 108") for my 
old coil, out of 1.9" OD Sch 5 aluminum tubing.  The toroid 
cage will consist of 11 ring sets, and 12 radial supports. 
SolidWorks tells me the finished toroid will weigh about 140lbs.

A JPEG of the new toroid can be had at:
