	The "big  boys" with high-speed winding machines put a plastic funnel
over the end of the spool.  Helps prevent tangling.  As the wire size
increases a point is reached where the twisting may not be tolerable,
but the wire is then strong enough to be taken off the reel when it is
mounted on an axle. (Dowel rod, piece of pipe, etc.)  I've wound #30
successfully both ways.
