Large HV electrodes are often made with many smaller "blobs", because making a single smooth thing in large sizes is difficult. Remember you can't have screw or bolt heads holding things together. Th other approach is to use tubing in rings. Especially if you want to be able to break it down and transport it, one of those forest of mushroom surfaces works pretty well. It's possible to make passable toroids with small spheres or small tubing, but if you look on Google for "mandrel bent elbows" you will find several companies like Global Technology and Engineering who make excellent 90 degree elbows. Get four of these and cut at the tangent points and weld into a toroid. I have used Global's elbows and they are fine. You can also leave some of the straight sections and get a rectangular "toroid." Example from Global--5" dia tubing, 7.5" bend radius, 10" straight sections, $34.70 each--you need four.

I have been wondering lately...why does Tesla's patent 1119732 and other designs show the topload with a surface covered in rounded bumps? I assume that this prevented breakout to some extent as he was intending to create a corona effect according to the patents. His intent was wireless transmission of energy. We design our coils for a light show. Has anyone ever tried to re-create the surface indicated by his designs? If so, what was the effect as compared to the smooth toroid with and without a single breakout point?
