I posted the text of the popular electronics (1964) article that had the 
square primary - it's probably in the list archieves somewhere.  I
scanned the 
article into MS word (word 97) and mailed it out to a bunch of people -
maybe 
someone put it on their web site???  Anyway, the general consensus from
the 
list was that the design was terrible.  I built it twice and it didn't
work 
either time.  I built the same thing a third time using a flat 1/4 inch
copper 
tubing primary and a secondary of half the number of turns in the
article and 
it's working (not well like the "real" coils on this list, but it
works).  The 
square shape is for esthetics and can't help but degrade the magnetic
field.

My first (and probably biggest) question  so  far is what shape of
primary 
should I use as a beginning?  Also, I saw
in
one magazine (Popular Electronics?) while I was still in High School,
that
one made a TC with a square primary, flat rolled.  Would this work
better
or worse than a round flat and/or cylindrical wound coil?
