[Elecraft] Trouble With Torroids

[Treat Hull]

Can someone enlighten me as to the proverbial problem that seems to come up
with torriods? Just build a K1 and found the torroids straightforward to
wind, strip and tin. The unit fired up flawlessly. Maybe it's because I'm a
sailor and found winding torroids an awful lot like whipping line (wrapping
small twine around the end of rope so it doesn't unravel). Beginner's luck
on my part? Or am I missing something?
