How do you make a toriod (top load) for a tesla coil?

How do you make a toriod (or top load) for a tesla coil? I don't want to buy a top load, or aluminum for a top load, so how would you do it with something like foil, and paper mache?

One of the easiest ways is to go to a home improvement store and purchase a flexible dryer duct made of aluminum. It is expandable and very light weight. Make a support for it and set on top of the coil. Practically ready made.
