I never thought of it as lefthanded or righthanded, I just hold the core in
my right hand and 'sew' the wire downward through the hole with my more
agile left hand - I can see the turns better than winding fro the bottom up.
The 'righties' would hold the core in the left hand and 'sew' the wire
upward though the core center to produce the same thing.

I do not believe I have gotten my 15% yet either <G>

----------------------------------------


I can't begin to count the number of "Elecraft" toroids I've wound over the
years and, as a leftie, I still have to stop and think for a moment when I
start one in order to get the windings going the right direction. Add to
that a touch of dyslexia, which seems to favor lefties, and I have to be
real careflu...er, careful.

Topological trivia for y'all. Which Elecraft toroid is correctly wound
LEFT-handed? 

Answer below:





The answer is L1 in the T1 ATU. It's a three-turn winding that fills the
space normally left open on toroids. So, for the leads to fit the pads on
the board, it must be wound in the opposite (left-handed) direction, unlike
other Elecraft toroids.
