Straighten, clean, measure and cut all wires. Twist two strands of 16" 21-gauge square wire with a wire twister. Place the twisted strands as the second one in from the outer end of the bundle. Bundle all 8 lengths of 16" 21-gauge square wires make one end flush, (tape the bundle at the ends and middle to make it easier to hold). Measure from the flush end 1" and mark, then measure from this point 3" down the bundle and mark.
Repeat down the bundle and you should have five marks which are 3" apart. Use 4 ¾" length of 18-gauge half-round wire, make a hook that will cover the bundle, wrap around at the mark five times. Repeat at each mark on the bundle. (When all the wraps are complete and bundle is secure you can remove the tape if used)
