Bruce/Dianne:
I am curious about the removal of toroid wire enamel covering
material in preparation for winding. Is it essential that bare wire
not touch the toroid ring?
Most of the toroidal cores (ferrite, colored cores) used in Elecraft
kits are NON-CONDUCTIVE, so it's not nearly as important to not have
a bear wire touching the core.
However, some of the non-ferrite cores may be somewhat conductive.
I usually try to tin the lead up about halfway PAST the bottom edge
of the core, so that when I install the inductor, and when I PULL on
the lead, to snug it down, I'll pull the TINNED part of the wire into
the plated-thru hole while NOT pulling in any UNTINNED part of the lead.
Hope this helps a bit.
73,
Tom Hammond N0SS
