servo wires

[mike mueller]

 This site sells twisted servo extensions for a real decent price:

 I'm not sure if they work. Has anyone used them? Thanks, Mike

A slick way to twist the servo extensions quickly in a neat manner is to
make a 'J' hook from music wire and then chuck it up in your variable
speed drill.

Put the hook around all 3 wires on one end and hold the other end in a
vise or clamp and slowly run the drill while keeping tension on the
wires. Don't pull too hard as the tangs holding the pins in the plastic
shell can break.
Slightly over wind the wires because there will be some tendency to
unwind until the wires and plastic insulation take a set. As the wires
wind up, the length will become shorter so allow the drill to ease
toward the other end.
You can speed this up a little by using a hair drier to heat the
insulation while you are winding. Don't get the wires too hot as you
don't want to melt the insulation.
You can hold the twist on there a while too while the wires take a set.

Keith's procedure is a good one if you need to keep the wires together.
Another reason for twisting them is to allow the ground wire to become a
simple shield from interference. If this is your goal, you need more
than 2
twists per inch. Rule of thumb is 5 per inch.
