Nick:
One problem I had winding coils was the first turn always was looser
than the rest. So I would intentionally wind an additional turn and
then remove the first turn. Just make sure you end up with the correct
number of turns.
Also, after the coil is wound, before I try to strip the insulation from
the ends, I do a fit check and trim the wires so they are only perhaps
1/8" longer than need be. I then remove the coil and know exactly where
I need to remove the insulation. If you don't do that, you will end up
spending lots of time stripping insulation from parts of the wire you
are going to trim off anyway. Once you think you've stripped off the
insulation, do a resistance check before installing the coil. After you
install it, other components in the circuit might lead you to believe
all is well when it isn't.
Good luck. If you are careful, you should have no problems.

I am just starting on my K2 and feeling apprehensive about coil winding - never
having wound a toroidal coil.My inclination is to wind them myself rather than
give way and buy a set. It all looks straightforward in the instruction manual.
Would welcome encouragement or cautionary advice.
