[Elecraft] Tororids

[Jozef Hand-Boniakowski]

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.
