Step 1: Materials Required
You also need a lamp socket, switch, and lamp cord. I found a candelabra cord at a building center that had all three items included.
The base for the lamp I built is the decorative cap from a ceiling light fixture.
You will need to cut a plywood disk that fits inside the ceiling light fixture cap. And, you will need two L-shaped screws (photo 3). I made my own screws by bending a 1/8th inch diameter copper rod and threading the long end for 6-32 threads. You will also need a couple of nuts to screw onto these L-shaped screws.
For an adhesive, I used high temp hot glue, but epoxy would work just fine as well.
The tools I used were a hot glue gun, soldering iron, drill and bits, and a rotary tool with grinding stones.
The candy jar will be inverted and placed on top of the ceiling light fixture part, and attached by using the two L-shaped screws to pull the inside shoulder of the jar against the base. I suppose you could just glue these parts together, but that would make it rather difficult to replace the light bulb in the future. By using the screws, everything can come apart with ease.
Step 2: Preparing the Base
I also used the rotary tool with a grinding stone to enlarge the center hole just enough so that the candelabra base could be press fit into it (photo 1).
Next, I measured and cut a thin plywood disk to fit inside the flat part of the ceiling light fixture part. This will keep the two L-shaped screws very straight, and make it much easier to install the candy jar onto the base. You will see how this goes together in a later step.
Step 3: Installing the Electrical Socket
Next, I passed the lamp cord through the wooden disk and soldered the wires back together and insulated the connections with heat shrink tubing (photos 3 & 4).
Step 4: Assemble the Base and Test
The L-shaped screws were installed from the top of the base, and the nuts attached, but not tightened.
Photo 2 shows the completed base (with a candelabra bulb installed).
Step 5: Attach the Candy Jar to the Base
This made for a really neat lamp. The facets molded into the candy jar make an interesting lighting effect.
