Twist the square wire with a drill or electric wire twister and set aside. Here are a few simple instructions for twisting your wire:
a) Open the jaws.
b) Set an end of the wire the gap and close the jaws, trapping the wire. Make it tight.
c) Hold the other end of the wire with flat pliers with one hand and hold the twister with the other hand.
d) Start the drill at a slow speed and gradually increase. Any speed is fine as long as everything seems tight and under control. I like to go just slow enough to see the wire twisting so I can check for spots that are getting overly twisty.
e) Stop when you like the look and remove your twisted, straightened wire.
