Perhaps, I will run afoul with the list crowd, but from the get go on my
first Elecraft kit, a K1, S/N 02326 (finished 5 days ago), I could not
get fond of burning the enamel off. I tried the fine sand paper route
wrapping a 3 inch long X .5 in wide strip around a plastic drinking
straw and securing with tape at just the ends of the wrap. That worked
but was far too slow. So, I went back to the way I had done it as a kid
and used a small sharp pen knife at 30 degree angle away from the toroid
while rotating the wire. I found I had the best control using the pen
knife, being able to start the stripping precisely where I wanted. I
wore magnifying safety glasses and made no nicks that I could see. The
K1 fired up perfectly the first time and has been running ever since
(about a week). 22 countries and 17 states worked so far on solar
power. Love this little radio.

No it won't but not sure that is going to help you.
What method are you using to tin the leads?
I as well as most others have had great success just burning the enamel off
with solder and an iron. I keep a 40 watt iron hot and just keep feeding
fresh solder to it with the winding lead on the iron. The enamel always
melts and the impurities flow away.
You need to get that coating removed 100%.
Tell us a little more about your technique.

I'm having trouble tinning my toroid leads. In spite
of rigorous cleaning they just don't want to accept
solder ( Kester 44 ). Will adding some paste flux
interfere with electrical qualities of the leads ?
