It's easy to overlap the 1/4 turn joints by 5 inches and fasten
together. The overlap areas would be silver plated with Cool Amp
powder. My plan at present it to use 5 inch wide x 1/4 inch copper
buss bar to form the primary in 1/4 turn sections.

If we want to concern ourselves with eddy losses, then perhaps a flat
vertical buss-bar type primary is better than a round conductor (just
like those ribbon primaries Terry Blake and others make, just much
thicker!). Most of the magnetic flux leaves the primary perpendicular
to the horizontal plane, so the copper is smallest in that dimension,
reducing eddy currents. Maybe with some training with FEMM (or other
programs) i can take a look at what kind of gains there may be to
