Dave -
I use two internal baffles in each secondary, each sealed in place about
one form diameter inboard of the ends of the secondary coilform (6"
coilform, locate baffles 6" from ends). For esthetics and protection of
the secondary winding, I run the ends of the winding inside the form, but
outboard of the baffles. At the both ends, I terminate the magnet wire to
a robust standoff insulator mounted to the center of the baffle. A
separate wire is run up to the topload or down to the RF grounding point.
This, any "accidents" involving the topload or ground lead won't break the
actual magnet wire, just the replacable wire running from the standoff up
to the topload or down to the ground connection.

Regards,
Scott Hanson
