You will need:
-Assorted plumbing parts (I used 3x 3/4" T-joints, 2x 6 inch lengths of 3/4", 6x 3/4" 90 angle pieces, one 3/4" to 1 1/2" bell reducer, and 4x 3 inch lengths of 3/4")
-Drill (dremel could probably work in a squeeze)
-Standard lightblub socket
-A cool lightbulb (I got a full spectrum 60 watt round bulb)
Step 1: Buy Some Plumbing Parts
Step 2: Buy the Rest of the Stuff
Step 3: Wire the Lamp
Drill a 1/4" hole in through a convenient spot on your lamp. Be sure that when you're drilling through the metal you drill slowly.
Run the power cord through the body of the lamp and up to the joint where the bulb socket and power cord meet each other. Strip back about an inch of either of the power cord wires. Solder the bulb socket wires and the power cord wires together, then reassemble the lamp.
Step 4: Insert the Rotary Switch
For the sake of convenience I went ahead and picked up a rotary switch much like the ones that some cheap lamps have. To install the switch, cut one of the two wires on the power cord, and leave the other intact. Run the continuous wire along the top of the rotary switch (should be fairly obvious, using the plastic walls inside the rotary switch as a guide) and the cut wire should run into two separate areas inside the switch where the wires terminal. Be sure that the two brass prongs that clench the wire when you screw the switch shut again come down in the center of both ends of your cut wire so that a solid connection is made.
