Hand Decorated Table Lamp With Bottom Light, Rewired

A customer brought in this Gone-With-The-Wind or Parlor style table lamp and wanted it to be rewired. After an initial inspection, we found the cord was not polarized and the top socket was worn.

The lamp parts needed for this repair include:

1) 3-Way Socket Interior With 1/8F Hickey
3-Way Socket Interior for 3-Way Light Bulbs. Medium base (E26) turn knob socket with 1/8F tap hickey, full paper insulator and short mandrel. 250W-250V

2) 8 Foot Brown SPT-1 Cord Set (Brown [item 46710] was their choice, any color polarized cord set would work.)
46710 - 8 ft. Length, Brown 18/2 Plastic Covered Lamp Cord Set, SPT-1

To disassemble this lamp, we will need to remove the socket. This lamp has an unusual socket, there is no cap or shell. It has a hickey on the bottom inside the gallery. You will first need to unscrew the key from the socket. Then, you will unscrew the hickey from the socket interior. A small flat head screw inside the socket connects to the hickey.

With the old socket removed, unscrew the wire terminals and pull the old cord down from the lamp base.

Untangle the wire to remove from the bottom light wire. Using the new lamp cord, twist the bottom light wire to the new lamp cord. The cords should match: smooth wire together and ribbed wire together. If the bottom light has a black and white wire, the smooth wire connects to the black wire and the ribbed wire connects to the white wire of the bottom light. With the wires connected, push them up the lamp rod to the top socket.

Connect the lamp cord to the new socket interior. Since we have a 3-way socket, the smooth wires each have a screw terminal. The smooth wire from the plug attaches to the brass plated screw terminal. The smooth wire from the bottom light connects to the black screw terminal. Both ribbed wires connect to the nickel screw terminal.

In some cases (like this one), you can get lucky and use the old hickey on the new socket. For this lamp, we removed the hickey off the new socket and used the original hickey on the lamp and the flat head screw from the socket. Just be sure to pull wires down the lamp to avoid excess slack around the socket. Slip the new insulator over the socket and screw on the old lamp key.

If the bottom light was removed for this installation, simply snap it back in place. If the bottom light needed to be replaced, now would be the right time with the cord replacement.

With a few good bulbs in place, we test the lamp.

Cluster Removal and Floor Lamp Rewired

A customer brought in this floor lamp the other day and wanted to change the socket arrangement. The lamp had a 2 socket cluster with pull chain sockets on each side. This limits the shade options to rectangle or large, to fit over these two sockets. The customer instead wanted only 1 socket with a harp. It would really open the shade styles and sizes for this lamp.

As with every repair or replacement, we inspect the lamp and make a parts list. For this repair, we need:

1) Heavy turned socket in Antique Bronze finish.

1) Harp Saddle in matching Antique Bronze finish

1) 18 Inch Threaded rod

1) Harp in Matching Antique Bronze Finish (Size depends on shade)

First, we want to remove the old cluster and get down to the threaded rod. The wire nuts are clipped off and the lamp and the cluster unscrews from the rod.

We continue to remove the check ring, tubing and other body pieces to find the other end of that old threaded rod. All of the parts are slipped onto the lamp.

With the other threaded end found, we can unscrew the old threaded rod from the lamp.

Our new threaded rod goes right back on the lamp. These thread sizes are universal in the lighting industry and are known as 1/8IP. They measure about 3/8 inch wide. The replacement rod is fully threaded from one end to the other. This allows the user to tighten as much as needed to get the right height (handy for replacement or repair). You could also cut the rod down to the desired length without re-threading the rod. With the new rod on the lamp, we can start to replace the floor lamp parts.

Now we are ready for the harp base or harp saddle.

Next the socket ring and socket cap go on the lamp. The socket ring sits on the harp saddle while the socket cap screws onto the threaded rod. This socket has a locking screw to keep the socket in place.

Now we are ready to tie a UL Knot in the lamp cord and attach the rest of the socket. The cord is split, tied, and stripped. The smooth wire connects to the brass screw and the ribbed wire connects to the nickel plated screw. The socket shell slides over the socket interior and is held to the socket cap with the screw collar.

Now we can add a bulb and test the lamp.

Brilliant! Another proper lamp repair. Total Cost < $30 Total Time < 45 minutes
