Terry,

You did quite a lot of electrostatic modeling. How important is the actual
complete toroid considering the inside is a flat plane generally?

I just got of the phone with a boat fiberglass repair expert. Suppose we
were to make a large alum duct toriod as usual on a large flat surface, and
wrap it in fiberglass or yet to be discussed fabric. They have epoxy spray
guns and could gel coat them for real smoothness and keep it thin enough to
be unnecessarily too heavy.

I liked the idea of nickel paint they use on cheaper plastic PC covers for
RF shielding. Hey it Passes class B or C FCC, should work great. Anybody got
a cover or some of this paint to use as a target for testing?

Hi,

If it were not a toroid but two disks of sheet metal with a round
edge it should so as well.  Then just a "hoop" of rounded outside
metal is all that is needed.

In other words, imagine a 6 x 24 toroid with an 18 inch hole drilled
down the center, you are left with just the 3 inches of rounded
outside edge which is all you need.

Then the only hard part is to fabricate the hoop.  So you take a long
strip of metal and pass it through a forming machine to round it over
and curve it.

Then you could probably just solder or pop rivet it together.

Just a thought...

Cheers,
