I really like the simple shape of the cube, so I wanted to make the piece as bare bones as possible. The framework is welded from 1/2 steel rod. Its definitely one of those pieces that looks simple but takes some time to ensure you come out with a sharp 90 at every angle.
I chose two separate sizes to add some contrast, both still large enough to make for a good usable area but small enough to keep a lower profile at 20″ and 16″ tall. I chose a walnut top consisting of a group of staggered 3/4″ pieces I ripped and planed with a layout that looks as if the top is floating over the cube. I welded 3/4″ clips to the top to hold the piece in place at 4 points. It looks really delicate but it is actually quite strong, adding a 3/4″ strong back to the bottom, running perpendicular to the walnut pieces for additional support.
