Re: [TCML] Coiling tips & tricks?

We used an old ice cream freezer motor for winding a coil 12" dia and 36" long. They go about 1 rps, and it took about 30 minutes to wind the coil, bifilar with #26 separated with 15# monofilament nylon. A foot pedal is almost a must. You have to keep about a 1 or 2 degree negative lead and hold a gloved finger on the point where the wire joins the existing turns. You can wind into epoxy this way.
Feed the wire off the end of the spool to keep the inertia low. Put a sleeve of t-shirt material over the spool so the wire doesn't flop around.

Keep the rest of the freezer for the after-coil party.

Motor and foot pedal salvaged from an old electric sewing machine (free
junk), geared down and hooked up for two uses:

1. Very slow fixed rpm (5 rpm) used for drying varnished/sealed coil forms
prior to winding (and after if desired).

2. Higher speed variable (10rpm+) for winding the coil itself.
