I needed a spiral staircase for my boston loft so I made one out of plywood from Home Depot using a small CNC from inventables along with my ryobitoolsusa This was a 2016 project that made out of need but I like how it demonstrates that small robots can make big things when used strategically. CNCs have evolved dramatically in the last 7years and are now fairly common in woodworking. #spiral #woodworker #woodworking #stairs #stairdesign #architecture #cnc #cncmachine #cncmilling
