Continuing along with one of my earlier posts, I figured that I would focus in on the building of an Edison lamp. In this case I wanted to show two of the aspects of the build that I don’t usually give a lot of attention. For the lamps, I’ve started using a full range dimmer switch. The switches are a little larger than the ones I used to use, but the ability to dim the Edison bulbs is worth it. The lights are capable of being used as a room light source, but for the most part they are a decorative piece of furniture. And when the light is dimmed down low, it’s really easy to see the patterns of the filaments in the bulbs. The challenge is to make room for the switch. First I locate the position of the switch and then move over to the dedicated mortising machine. The goal here is to make the back of the lamp thinner where the switch is located. Next I need to take a forstner bit to make room for the knob. It’s important that the knob is recessed into the lamp to improve the overall appearance of the piece. The photo below shows a quick test fitting of the switch.
The next aspect I wanted to highlight was the location of the holes for the sockets. In all of my lamps, I use a wooden board to attach the sockets to… The challenge is to get the hole for the light socket nipples dead center in the larger diameter hole that exposes the sockets. I start by sizing the support board so that it fits perfectly inside the top lip of the lamp. Then with simple layout lines, I locate the center point of each bulb (shown in the first photo below with pencil lines). From here I’m able to use a drill press to drill a series of holes at each location to generate the final cutouts shown in the second photo. The process starts by drilling one hole through the support board and the top at the same time. This is followed by making the hole in the support board just a little wider to fit the nipple. Finally after removing the support board, I cut out the larger diameter hole to fit the socket.
In the next post, I’ll highlight more of the interior working of the Edison lamp. Then it’s off to finishing.
