how to strip large diameter copper wire Answered
If you have say 2 inch or better diameter copper wire to strip here is what I do. I have ben in the scrap arena for years. Buy a large handeled pair of shears that are only for copper. They will look much like a large pair of boltcutters. Cut your insulated wire into about two foot lenghts. Get a large pot, the bigger the better and heat with an out door propane burner full of water. Place the cut sticks of wire into the boiling water fro about five min. Get some insulated rubber gloves and a sharp razor knofe and you will find that the plastic insulation carves away like butter. This works on everykind of insulated wire I have come across. With lead wrapped insulated wire, get a plasma torch. It cutts easily and is so fast the plastic wire inside does not have time to catch on fire. Use plenty of ventilation to avoid breathing lead based fumes.
