Making twisted wiring harnesses with a hand drill
My dad learned this trick from a stereo installer when he worked at a Honda dealership. If you use similarly-sized wires, the resulting twist pattern is very uniform and professional-looking. Cut off a bunch of pieces of wire, then stuff all of the ends into a the drill chuck and clamp it down. Start the drill turning, and use your other hand to keep tension on the wires.

Heh, I've done this to untwist cat5 when I didn't have spare wire the right gauge for projects. I'm a dad now, guess my kids will learn from me too! :-)
ReplyDeleteThat method will subject the conductors to some pretty heavy strain, and the harness will also try to untwist itself.
ReplyDeleteThere's a similar method you can do with a drill where each wire is passed into a fishing swivel and those swivels are, in turn, attached to a board and a post that goes in the drill chuck. The wires are wrapped around eachother in a spiral and the lay of the wire will make them stay put without damage to the inner conductors.
Don't "twist" your wires.
