Just wondering if there isn't some cheaper way to construct rigid
toroids than the spun aluminum construction.  Bundt pans (those baking
pans that make a cake with a whole in the middle) are more or less half
a toroid, although they usually have decorative embellishments that are
not desirable for  Tesla coil toroids, and are not big enough or the
right dimesions for most.  But they're cheap, which makes me think that
there's a cheaper way to produce half a toroid than spinning.

Any ideas how they're constructed, and whether big toroids could be made
this way?
