Idea on large toroid construction for Tesla transformers:

Another method that would work well would be a copper tubing 
toroid.  Using 1/2 inch ID (5/8 inch OD) copper tubing on a 5/8 inch 
spacing.  Each ring would be a slightly different size progressing 
smaller in size from the equator both up and down.  A simple frame of 
hemisphere slotted 1/4 inch plywood would form the center supports in 
each quadrant.  Notches would be slotted (hemisphere) in the edge of 
the plywood to hold the copper tubing rings.  A single copper wire 
would be soldered across all the copper tubing rings on the inside 
edge --- this connects them all together to achieve equipotential on all rings.

The hemispheres (notches) are actually drilled out to full size on 
the larger plywood structure.  Then the outer edge of the structure 
is sawed off leaving a hemisphere "notch" that the copper tubing snaps into.

The rings are soldered together using common plumbing copper tubing joiners.

The plywood parts would be sprayed with conductive paint to help make 
the entire structure more conductive and electrically equipotential.

This technique would be very cost effective.  Once the pattern is 
developed is could be made full size on cardboard and easily 
transferred to 1/4 inch plywood.  For smaller toroids Russian 1/4 
inch birch plywood used as flooring underlayment is available at most 
local lumber yards.  This material is very light in weight.  Larger 
toroids would use 1/2 inch thick plywood.

I first saw this copper tubing toroid in operation in 1961 at the 
"Lightning Laboratory" in Minneapolis where they were testing 
lightning discharges against missle cases.  It works well as long as 
the spacing between the rings is small.  The lightning lab was 
running a large 80 x 24 inch copper tubing toroid at 1.5 MEV.  This 
same technique would work the same on almost any size toroid such as 
24 x 6 inch and up.

This would be a smaller scale version of the large sphere that Greg 
Leyh has used on his large coil.

If time permits I would be interested in doing the development work 
when I get to Tucson in mid-Oct.

Scott H. --- this would work well for the coil you are presently working on.
