I found a way to make toploads easily in the modular style you can see at any bigger HV lab. For a small or medium sized coil probably a spinned aluminum topload is better (but more expensive). However with this way any non-conductive forms (especially for bigger coils) can be made to a usable topload and to produce a smoother EM field. I'm not finished with the prototype yet, but you can see what I'm talking about. Disks are held in place by very small Nd magnets glued to the surfaces of the topload form and to the inside of the disks (so they are detachable). Try to guess what are these aluminum disks!

Very nice. Reminds me of metal scales used by chainmail enthusiasts.
One vendor, theringlord.com, offers large aluminum scales for about US $10 per square foot of coverage. Anodized colors, other metals, etc. are available. How about a snake-scaled toroid? (image from )

A small toroid can be made with these scales easily, and will look interesting. I checked out a modular style potential sphere at the university. The form is made by steel tubes welded together and the aluminum disks are held in place by springs, which are behind every 2 tube.
