Steps on how to wire a turned lamp.
This instructable assumes you have a turned wood lamp base (or something similar) already made and finished.
If you haven't ever turned anything on a lathe, I highly recommend it.

Step 1: Materials and Tools
Step 2: Insert the Threaded Nipple
The wooden lamp base should have a through hole drilled through it (11/32"). Use a custom built hand tap to thread the wooden lamp base. Screw the threaded nipple into the base. Leave about 1/2 inch showing.
Step 3: Insert the Electrical Wire
Fish the wire from the bottom up. You may need to tape the wire to some string or a thin stick, if the through hole is not wide enough.
Using the wire strippers, expose about 1/2 inch of copper at both ends.
Step 4: Add Ring and Harp
You don't have to add the check ring if you don't want to. But I've found that the lamp not only looks better but it makes for a more robust base for the harp and lamp socket. And you don't need to add a harp if your intended lamp shade does not need one.
Place the check ring over the wire and threaded nipple.
Remove the base piece of the harp and place it over the wire and threaded nipple.
Step 5: Add the Lamp Socket
I can usually get my hands on some electrical cords (every first of the month somebody throws away a lamp on my block) and I get some good deals on wood. But I will always pay for top of the line lamp sockets. The best I've ever worked with are from Grand Brass (trust me they are the best]). The model I'm using here has a built in dimmer, and is so worth the money.
The lamp socket is composed of 4 parts: the ring, the bottom socket cap, the socket interior, and the socket shell. Place the ring over the wire and threaded nipple. Screw on the bottom base to the threaded nipple. Tighten the set screw when the base is secure.
Tie the ends of the wire into what is known as the underwriter's knot, this prevents it from being pulled back through the lamp.
Follow the manufacturer's instructions to find the hot and neutral wire (the neutral wire often has ribbing on it). Connect the neutral wire to the silver screw on the socket. Connect the hot wire to the gold screw. Tighten the terminal screws, making sure all of the wires are under the screw head.
Place the socket shell over the socket interior and tighten the ring.
Step 6: Let It Shine
Reattach the harp back to the harp base. Insert a light bulb and plug er' in. You could add a shade, but why would you, that socket looks great.
