[Elecraft] Winding Toroid cores clockwise,,?

[Roy Parker]

Ok, I'm going to stick my neck out here but see if I'm right.
    "Every time a wire passes through a core it counts as ONE TURN."   =
"Ain't no half turns."
    And,, "No matter how the turns are arranged, it's the number of =
times through the middle that count."
(Right?)


OK?  Now a new thought.  I'm thinking about the above to ponder the =
stuff below.

Even if two separate windings on the same core are wound differently the =
transformer should work. Right?
But phasing would change, you might have to ground the other end of the =
secondary for things to work correctly.
(Reversing the leads of one winding should change the phase relationship =
{& nothing more} ).  (Right?)


Ok, I'm holding the core in my LEFT hand, starting lead coming from the =
BOTTOM edge, poking turns INTO the hole,
accumulating turns to the RIGHT.  Is this called "counter-clockwise" =
(anti-clockwise)? =20
If you were to imagine cutting the core at the BOTTOM,=20
and put your head in there facing RIGHT, you would see the turns =
spiraling away "counter-clockwise".
(This is just the way I started doing things from the start, I don't =
mean to suggest any method is "right" or anything.)

And if changing only ONE thing;
passing the lead UP through the hole, or accumulating to the LEFT, =
winding around the TOP of the core,
it would change to clockwise turns.  (Right?)

All the cores in my K1 all 'looked prettier' wound the 'other way'. The =
outline matched the drawing on the silkscreen=20
when finished.


So, I started holding the cores the same way, but with the starting lead =
to the TOP.  Now I'd be gathering windings to the
RIGHT.  But the windings would be accumulating in a "CLOCKWISE" fashion. =
=20
Now,  If we make that imaginary cut in the core BOTTOM and put our head =
in facing RIGHT----- The turns are spiraling
away from our face in a CLOCKWISE fashion.  (Also clockwise viewed at =
the TOP looking LEFT.)

I have 'southpaw' tendencies, so how I hold and wind turns may be =
unusual, but I was wondering if this would
define "clockwise" or "counter clockwise" windings.



Also I learned on my own (and it's verified as a good practice by =
others) that it's easier to wind half the turns
then flip the core over to wind the other turns.  (You only have to poke =
half the length of the wire through at any time.)
(Also, you can tell if it the wire is too short by the time it's half =
done!)

All of this to say that the cores of my K1 'look prettier" when wound =
clockwise.
