Steel tie wire
Romex copper wire
Step 1: Get Wire
Cut a piece of tie wire 25" long, and one piece of copper romex wire 25" long, both available at the hardware store. You will need to use wire strippers and/or a knife (careful) to strip off the insulation. Or you can just use the already bare ground wire.
Step 2: Twist!
Fold the wires in half over the hammer, clamp it in the chuck of a hand drill, and twist it while standing on the hammer. Go slow, you will want a drill with a chuck key so you can clamp down tight enough. Cut the looped ends of the wires and pull it off the hammer.
Step 3: Hammer Time
Hammer the twisted wire flat on a hard surface. Be sure to look at it sideways from time to time to make sure you have created a uniform thickness.
Step 4: Cut and File
Cut the bracelet to length and file the ends so they will not snag.
Step 5: Bend
Using a combination of pliers with cardboard or rubber, a hard round object, and your bare hands, bend the bracelet to a comfortable shape. Be contientious of the ends of the bracelet so they stay together. You can touch up the ends with a little sandpaper after you are finished bending.
Step 6: Wear!
Nice! Keep in mind that steel will rust if it gets wet or salty. I protect mine by rubbing olive oil into it every so often, and if you take good care of it, over time the steel will age to a darker blue and the copper will glow a deep orange, something you can really be proud of :)
