Industrial Cast Iron Pulley Edison Lamp - Metal & Woodworking How To

In this video I make a pulley styled lamp from an old treadle sewing machine base.

This is a pretty straight forward project. I tried to cover all of the steps to make it achievable for just about anybody.

Here's the accompanying video for the project.

First I disassembled the old treadle base to get to the middle section and pulley. The side panels of the base were cracked so the casting was no longer good for supporting a table.

I removed the pulley wheel and extracted the center arbor. Then I looked for a good location for the pulley. Locating it on the center truss portion of the treadle base can be tricky. On this project there was a threaded knob that I worked very well as a mount.

I found a old bolt in my scrap bin that matched the threads. I had to cut it down with my hacksaw to make it fit.

The center arbor location need a bushing. I also found the bushing in one of my parts organizers. The bushing allowed me to mount the pulley firmly.

I found and marked the appropriate location to cut the truss. I also used my right angle grinder with the DIABLO Round Corner flap disc to reproduce the original profile in the casting.

I placed the cast pulley assembly on the plank of wood to find the correct locations to cut and drill. I used the original bolts to mount the cast assembly.

In order to use these tapered bolts I had to countersink the back of the wood plank. I used a 3/4" countersink bit.

I cut a channel into the back of the plank to make room for the lamp cord.

I used a common keyhole router bit to cut the keyhole mounting locations.

The cut end was too new looking. So I distressed it with a rock. I used stain and a black Sharpie marker to match the rest of the plank's surface.

I lightly sanded the lumber to remove loose wood. I then applied two coats of water based polyurethane (satin) to both sides.

I painted the cast iron with satin finish black spray paint. After it dried I began to assemble the lamp.

I disassembled the lamp cord so I could fish it through the back of the wood. I located it in the middle so it would go up and over the cast pulley.

I glued the lamp cord in place with a high-temp hot glue gun.

I glued the lamp cord so it would come out from the middle of the fixture and go up and over the cast pulley.
