If you haven't already, snip the end off the wire.  The cut end is much easier to feed through the holes in the spacers.

Starting at the base, feed the wire from the back, towards the spacer at the front of the "shoulder."  Slide the wire through the hole, and pull through enough wire to reach all the way to the reflector.

Feed the wire behind the first pair of springs, towards the "elbow."  Feed the wire through the spacer here, being careful not to twist the wire.  A twist won't affect the performance of the lamp, but it will look unprofessional.  Can't have that, right?

Continue feeding the wire towards the "wrist," over the dowel that connects the two parallel arms of the "forearm."  Poke the wire through the spacer at the wrist, and draw the wire tight.

Disassemble the bulb socket, to reveal the two screw terminals.  Feed the wire through the end of the socket housing, and pull through enough wire that it's easy to work with.  Split the two wires apart for about 2", then strip about half an inch from the end of each.  Twist the strands of wire so they don't fray.

Secure one wire onto each screw terminal; it doesn't really matter which goes where.  Double check for any loose strands that might short out and fix them.  Now, reassemble the socket assembly and screw in a light bulb.  Plug in the other end of the cord, and turn it on.  It should light up!

Unscrew the bulb again, and slide the socket into the hole at the center of the reflector.  When you're satisfied with the fit, apply a dab of epoxy around the perimeter of the socket where it contacts the wood of the reflector.  Before the epoxy sets, make sure the switch is centered between two "fingers" on the reflector.

Once the epoxy is cured, attach the reflector to the arm using the 1/4" bolt.  A washer should go on either side of the wrist joint.  Place a 1/4" spacer on either side of the reflector.  Tighten the butterfly nut until the reflector stays where you placed it.  Too tight, and the wood could be damaged.

Screw the light bulb back in.

Finally, pull back any slack in the cord, to neaten the appearance of the lamp.

And that's it!  The Woodpunk LED Desk Lamp is ready for action!
