Hi all,

  my winding jig is a small AC gearhead motor I got for $7 at a flea market.
It came out of a good-sized motorized display.  It's 32.1:1, the motor is
1800 RPM, so it's okay speed.  I mounted it to a scrap of wood by cutting a
hole for the shaft and drilling 4 small holes for the motor case bolts (just
long enough to get some nuts and washers on).   The board I screwed to a
scrap of 2x4, and clamped to my lathe, using the tailstock of the lathe for
freewheeling end.  You can do it without the lathe, though at ~40RPM or so
it takes awhile to wind a coil.

  The advantage is *power!*  That gearhead motor has the raw grunt to let me
keep a high amount of tension on the wire.  I keep the tape strips handy
too.

 Treadmills, trash kid's toys (the powerwheels toys), etc are good sources
for motors suitable for winding machines.  (I've seen 3-4 treadmills being
thrown out so far this year).  Couldn't get there before the trashman
though. :(  A motor, combined with some moderate work can yield a great
machine.  I only planned to use mine once, but it works so well I'll
continue using it (what other use do I have for a 40rpm motor?!!)

    I have also wound a couple of these same forms by simply holding onto
 the secondary from and turning it in my hands, with fingers again
 applying tension to the wire.  That takes about two or three times as
 long, but if the start of the winding is made nice and square with the
 form, results in a very nice looking coil.  Same precaution about
 pre-cut masking tape.  I would think this method would work pretty well
 for large forms provided the wire isn't so large that it can't be held
 tight enough to get a smooth and tight coil.

    Of course, for the big jobs most of you guys seem to be building,
 something more heroic is reuired!
