K-Mart and Big Lots also occasionally carry different sizes
of pans for those who have ethical problems with Hobby Lobby.

If you have a hobby lobby in your area they sell an assortment of pie pans in
different sizes.

Thanks Jon!
I've been putting many hours in every day trying to get it ready
for the
showing next Friday. When you say make the toroid topload bigger,
I'm
assuming you mean use larger ducting like 8" or larger if I can find
it
(instead of the 6" I have now). It was hard to find the right size
middle
section and was lucky to find 13" foil pizza trays (as the 4"
ducting
torroid toploads use more easily found 9" pie tins). I also used
foil
wrapped cardboard inside for more strength but it wants to shift around
too
much unless kept tight. Is it more important to have a larger middle
section
to the torroid topload or the ducting size (i.e. 6", 8", 12")? It
might be
easier to locate a more ridged larger middle section and wrap the
6"+ ducting
around that,
Also wrapping it all in aluminum tape would keep it more uniform
and flat
(less crinkle like), I also found that adding a large spike nail to the
top
of the torroid middle section (wedge in) would direct more sparks out
the
end of it. So making it more uniform (or bigger) will allow for less
medium
sized sparks and will discharge sparks that are thicker and
longer?
