I was just thinking that a special tool might be handy here. In the
aviation world, whatever bolts aren't held with locking fasteners or
cotter pins are safety wired. To make safety wire installations clean and
consistant, there's a special kind of pliers with long handles, a lock
and a knob on the end.
Basically, you put the ends of the wire into the jaws, squeeze until the
handles come together then lock them. Then you pull the knob, which puts
about 7 even twists into the wires. Release and pull again, 7 more
twists. Repeat until the wire is twisted as much as you need, then
release, and use the built-in cutters to trim off the excess.
My set of pliers is probably too short (6") to allow the handles to flex
enough to close on 14 guage wire. But others are typically 8-10" long,
and might be useful, especially up on the tower.
