William,
Last September, Wild Bill and I experimented with an oil filled
magnifier driver, and we did use a secondary coil which is wound with
6 gauge rectangular wire. The wire is on edge, which gives a maximum
TPI. It was a commercial coil taken from a large transformer that we
had scrapped. The coil worked very well, but we never were able to
contain the high voltage, even in an oil bath. We eventually gave up
on this idea and went to a conventional driver, ala Hull. You very
likely could wind a coil using rectangular coil, but it would have to
be very soft wire, you'd have to use a special wire guide/jig, and
you'd have the best luck with a coil form with a big radius of
curvature.
