This is how you can turn single strand electrical copper wire to make jewelry, in this case a cuban link bracelet. The steps are the following:
Strip the insulation
Straighten by twisting both ways with a drill
Clean remaining residue
Coil around a rod (the diameter of the rod should be more than twice that of the wire)
Cut the coiled wire lengthwise to form individual links
Assemble links then closing them using two pliers
Weld them shut (I am using a TIG welder but you can braze them together)
Twist the whole chain to form the desired "twisted links"
Flatten with a hammer
File down one side of the chain to get the cuban look
Sand and polish for looks and you are done!
