Well, I am happy that you are helping out the hobby,
but I have to differ with you on the contention that
secondary coils take a long time to wind by hand.  If
you have a wife or partner to help, it can be knocked
out in a hurry.  I wound my 6" dia 24" long secondary
with a temporary jig set up between two collapsable
aluminum saw horses.  I had a cheap wooden dowel as
the shaft for the spool of magnet wire, and endcaps
with carriage bolt axles in the center for the coil
former.  After using masking tape to secure the wire,
I spun the form with both hands while my wife kept the
rate of spin on the spool constant as well as guiding
the angle of the wire.  I was also making sure the
wire was tight and flush before putting a piece of
temporary tape over each new few inches of winding.
We knocked out the whole job in just 45 minutes!
Perfect secondary, no overlaps, kinks, gaps or
problems at all.  I have also wound others since then
with equal success.  The great thing too, is that you
can start applying coats of polyurethane (or whatever)
while the coil is still sitting the the jig.  Then
after you are done, you can just untape the axles and
everything and collapse the sawhorses and store them
away for later.  I used aluminum tape for the axles,
since it has a much stronger adhesive.
