Infinity Cube Lamp

This is an infinity cube lamp with a solid maple base that is approximately 5.25" x 5.25" x 8.5" tall with an Edison style dimmable bulb. Infinity cubes are visually intriguing and have been on my project list for a while now. My first attempt at making one out of wood was unsuccessful because wood lacked the rigidity needed for this application. Instead, this lamp is made from about 8' of 0.5" x 0.5" square tube steel and that was cut into 18 individual pieces (3 unique pieces). For this project, I used this guide from Everything Metal and Wood that has a useful dimension calculator, isometric drawings, and cut list.

I sourced the steel from McMaster Carr and cut all the pieces to length on a horizontal cutoff saw that could be set at a 45° angle. Once the pieces had been cut, I deburred the edges with a belt sander. The preparation to figure out which piece had be welded to what piece was a key step in the process. I welded two mirrored pieces on the wrong side that I had to cut off with an angle grinder and re-weld. I used a Miller Multiprocess welder and the MIG process for this project. Every welded connection had to be ground down with an angle grinder and rounded on the belt sander which significantly increased the project time.

The base is made from an old Maple butcher block table. I drilled a 1.5" hole for the light socket which is secured in place with clear silicone caulk. The Maple base is finished with Danish Oil and secured to the steel infinity cube into drilled and tapped holes with 8-32 bolts. The cube was painted black with Rust-Oleum Semi-Gloss spray paint. The lamp also features an adjustable dimming switch to adjust the brightness of the Edison bulb.
