The Kid Should See This

Building a DIY CNC-cut spiral staircase

This DIY Spiral Staircase was made with just over sixteen 12-layer plywood steps that are each rotated 30 degrees around a central steel pole. Designer and YouTuber Ben Uyeda of HomeMade Modern designed the layers to be cut with a X-Carve CNC machine and assembled in his Boston loft. He recorded the process in the video above.

Learn more about how he made it in these step-by-step instructions, which includes a link to his digital drawings. The project (sans a safety railing that’s still in the works) cost around $900 and took 40 hours to complete.
