O W Lundgren. The big versions of the usual smaller spun toroids for
table top coils will probably require a 2nd mortgage. I think they
want something like $2000 for an 8x30 with the cost going up faster
than the volume of the toroid itself (cubed). Hence why you don't
see many big ones outside professional companies and the rest of us
resort to using chicken wire/plywood. At some point there's really
no advantage of spun over handmade chickenwire/plywood from an
electric field point of view, just looks better and cost thousands
more. Even if I was a millionaire I'd be extraordinarily depressed
if I accidently dropped it (probably easy to do with the big/awkward
ones). If anyone on the list would make ~8x30's and sell for
$400-500 that would be a bargain.

Hello list,
I'm trying to get the internet address and correct spelling for
Lundgren to price big toroids.
