If you can find a company that manufactures air-compresser tanks, or
propane tanks, or any kind of tank, cylindrical in form, with rounded ends,
the rounded ends make great discharge terminals when welded together. Grind
off the weld bead, and you're good to go. Cheap, and effective. Like a
toroid with no doughnut hole, ;) I'm not sure how the shape affects the ion
clound or field lines, but on my relatively small coils, these things
actually worked better than dryer-duct toroids...maybe because of the
smooth finish??
