75 years ago this month, the January 1943 issue of Radio Craft carried this hint for winding coils.

The idea was sent in by one Tony Calabrese of White Plains, NY, and was billed as a good method for anyone to get a professional looking coil.

One end of a designated length of wire was attached to the wall or some other fixed object, with the other end attached to the coil form. After a couple of turns, the weight was placed on the wire to maintain tension.

When the coil was complete, the weight was slipped off, resulting in a neat coil with evenly spaced turns.
