I disagree with the left hand right hand issue. I'm very right handed and
wound the toroids of my 1st K2 back words. However, when winding the set
for my current K2, I had to make a concise effort to wind them correctly
and it was awkward to do so.
BTW, I travel frequently for work so I brought all of the toroids and wire
on my recent trip. I sat at the desk in the hotel room and wound them all.
I did not strip and tin the leads... To much smoke. I was afraid of setting
off the smoke detectors.
Hey Elecraft! Why not put a separate section into the manual that describes
what core, what L or T number and the number of turns on each core. That
way, one can "pre-wind" all of the toroidal coils at the same time and not
have to stop and wind?
Just my 2cents worth.

PS my K2 is now operational as a receiver on 40 meters. Works great!

That's correct. There are no partial turns on a toroid.
As a leftie I had to overcome the same "sense" issue. Then came the T1! One
toroid in the T1 has only three turns, close spaced, so they end up using
only a small part of the core. The turns occupy the area of the core
normally left open on a toroid. As a result, the "sense" of the winding is
reversed! You have to wind that one "backwards" to make the leads lie up
with the pads on the board.
Oh, well, as Emerson wrote, "A foolish consistency is the hobgoblin of
little minds, adored by little statesmen and philosophers and divines. With
consistency a great soul has simply nothing to do. He may as well concern
himself with his shadow on the wall." ... Or, I might add, concern himself
with why the toroid leads don't match the holes in the PCB.
