Loosen the set screw on the socket at the top of the lamp, then unthread the socket entirely. To separate from the lamp, you'll need to loosen the terminal screws and remove the wires. After that, you can pull the wire out through the bottom of the base of the lamp. You may need to remove the cover on the underside of your lamp to access the wire output depending on the design of your lamp. Finish by pulling the lamp shade harp off of the lamp.
Angie's How To Rewire a Thrift Store Lamp
As a purveyor of thrift store treasures, I tend to come home with pieces that need a whole lot of love and attention—from furniture in desperate need of refinishing, to art that could stand to get reframed. My most recent purchase involved a vintage lamp that, happily, sported a beautiful brass finish, but unhappily, came with a broken plug. The good news is that it was nothing that a little TLC and DIY action couldn't fix. Read on to learn how you, too, can rewire a secondhand lamp to make good as new!
Use a pair of wire cutters or a wire stripper to cut off the old plug. To do so, simply snip right through the wire at the base of the old plug. As long as you have inspected the original wire thoroughly (tip to tip) and don't see any damage, it's okay to reuse. But if you see any cuts or exposed wires, discard and use a new wire. In our case, we were able to reuse the original wire after cutting off the broken plug.
Lift your lamp base and slip your new or refurbished wire into the opening. Push up through the base until the wire comes out through the top of the lamp.
Next, use your finger tips to gently pull the two sides of the wire apart, and then use a wire stripper to strip insulation about half an inch from the ends of both wires. Then, use your finger tips to twist the exposed wire to prevent fraying.
Separate the halves of your new socket. Slip the now-prepared wires through the new socket base and thread it onto the lamp. Tighten the set screw to secure.
Grab the top half of your socket for rewiring. Run your fingers over your wire—one side should be ribbed, while the other is smooth. Loop the smooth wire around the gold screw and tighten. Then, wrap the ribbed wire around the silver screw and tighten. Bending your exposed wires into a hooked shape beforehand will make this step easier to complete.
Pull the excess wire out of the bottom of the lamp base as you simultaneously push the top half of the socket onto the bottom half. They should slip together with a bit of wiggling.
Loosen the set screw in your new plug to open. Next, repeat the same process used on the top end of the lamp—the smooth wire is exposed, twisted and screwed around the gold screw, while the ribbed wire is exposed, twisted and screwed around the silver screw.
Ensure that the wires are separated around the set screw in the plug and then close the plug around the wire. Tighten the set screw in the plug to finish.
Add a light bulb to the lamp, reattach the harp and lampshade and plug your lamp into an outlet to test—and ultimately enjoy!
