Most wire installed in the home has a sheath of insulation surrounding it. If you want to recycle the metal conducting wire inside this sheath, you'll need to remove the insulation before taking the wire to a scrap yard. To strip great quantities of wire easily, a handheld wire stripper just won't do the job, unless you're willing to spend hours to produce a small amount of stripped wire. Instead, you can make your own manual homemade wire stripper with some tools found in most home garages.
Drill two holes in your wood board. Place the holes a few inches apart from each other and about 2 inches away from the long side of the wood board, or, in other words, 2 inches in toward the center.
Cut the tip of your screw into a sharp edge using the grinder.
Insert a screw into the wood board so that its tip juts through one of the holes, then remove the screw and replace it with the sharpened screw. This action creates a blade that can cut your wire as you pass it through the hole.
Insert some wire into the hole with the sharpened screw tip and practice cutting the sheathing of the wire. Change the depth of the screw tip to cut only the sheathing and not the metal inside.
Feed wire from the spool you wish to strip through the hole that does not have the blade and then through the hole with the blade. Place your new wire stripper on cinder blocks, stand on the ends of the board to hold it to the blocks, and pull the wire through the hole with the blade. This action creates long cuts on the insulation. Simply pull the insulation off with your fingers once it's been cut.
