Step 3: Drilling the wood base.

I drilled a vertical hole where I wanted each light socket to be mounted. I really don’t know the diameter, as all of my drill bits are sloppily stored loose in an old ammo can. I just matched a drill bit with the lamp nipple that I wanted to use to secure the candelabra base to the wood. I then drilled a horizontal hole from the back of the wood base intersecting the vertical hole.
