	Another advantage of using child labor (labour in the US) is that if
the wire snags or breaks you can stop the turning instantly and correct
the matter, particularly if you keep a supply of pre-cut strips of tape
handy.  It's mighty hard to get a motor to stop in only a turn or two. I
learned this long ago when trying to wind long coils on my lathe.  I
think the extra time required to turn by hand is worth it.
