Make a Lamp from a Bottle

Step 3 Wire the Lamp

Place the harp base and socket cap on the threaded rod, and tighten down the socket cap with your screwdriver. Then thread your electrical wire through the hole in the cap, and tie a "underwriter's knot." (See image.) wrap the stripped ends of your wire around the terminal screws on the socket and tighten them down. Then slide the paper-lined socket shell down over the whole thing, and clip the socket assembly into the socket cap. There are little teeth that lock in to the cap's grooves, so just rock it back and forth until it clicks and is steady.
