HomeMade Modern EP99 DIY CNC Spiral Staircase

I made this spiral staircase for my loft in Boston. I used my X-Carve CNC machine by Inventables.com

to cut out the initial pieces. In the interest of time I had a friend use his machine which has a large bed cut out some of the pieces. Each step is made out of 12 layers of ¾” furniture grade plywood. You can download the dwg drawings that we used here.
