Hi Bill,

The toroid components are all standard aluminum, 6061-T6.  The ribs are 
water-jet cut, and the rings were rolled on the same home-made pyramid 
roller at SRL that I've used for the previous toroids:

The toroid appears to hold 500kV without breakout, as I have to add a 
small point to get any action off it.
