Hey David,
I was trying to find my catalog from Amidon Associates (where I get my
toroids) before I opened my mouth and inserted foot and replied to your
quandry. In the brochure, they have a listing that tells how many turns
for each gauge wire on any given toroid size can be wound in a single
layer. Usually, I pick the largest wire that should fit based on the
number of turns I need. Right or wrong, that's how I do it. I couldn't
find it and I didn't see it on their website either. Anyhow, I assume
you are winding with enameled wire? Regarless, good luck with the
project and let us all know how it works out!

Hi Scott I have tried and no way can i get 40 turns in without
overlapping, also is it correct to wind on only 80 percent of the core

Scott wrote:

Remember, each time the wire passes through the core is counted as a
turn. In other words, just passing the wire straight through the core
is one turn. 24 gauge wire should be fairly easy to get 40 turns in a
single pass. Toroids are usually wound about 330 degrees around (a 30
degree gap between start and end of winding)...

Good day I am putting together a Vectronics 80 Meter Transceiver
Kit , the problem I have is winding the T50-2 toroid , the
instructions state to wind 40 turns of 24 gauge wire, would that be
two passes of twenty as forty on a single pass is nigh impossible.
Help would be appreciated.
