Re: doubled up toroids

Hi guys,
What I've done isn't exactly two toroids, however it does amount to 
two toploads. The first is the old-fashioned two metal bowls taped 
together with aluminum tape, and then on top of that I've put, among 
other things, a 4" sphere which gives me some nice arcs. If you'd 
like to see an example, please check out my page 
at  http://users.ntsource.com/~zathros/arcs004.htm If nothing else, 
this keeps the strikes heading upwards and away from the primary and secondary.

Neal.
