In this video, Ben Uyeda of HomeMade Modern demonstrates how to build a sleek, contemporary spiral staircase using just a standard schedule steel post, plywood and a CNC router (along with a healthy amount of wood and construction glue). To build the staircase, Uyeda uses the CNC to cut out 12 shapes of incremental size from a plywood sheet, which he then stacks and fits around the post to secure into place.
