Subject: A Sticky Question

When I wound my coils using AWG 50 gauge wire (.001") the wire is rea=
lly too small to see with the naked eye...
so I had to use several brigh=
t lights so I could see reflections off the wire.
I used an old tape rec=
order drive motor... I put it on a rheostat so I could ramp up the speed. <=
BR>With a wire that fine once you start... there was no stopping until you =
were done... any jerking, or
restarting always resulted in the wire brea=
king. And there was no repair... just heating the wire was enough to make i=
t brittle and it would snap just bending it.

The other bad part of u=
sing that size wire... was that
 you never knew if the initial connection, at the beginning of
the wind,=
 was any good until you were done... and could check for continuity.
But you could sure get a lot of turns on a little one inch in diameter spo=
ol.
