Curved Dining Chair cnc-style wedged mortise joints

thingiverse

I publish projects that are typically well-developed, but this time is an exception. This dining chair is version six of a design process, which will likely continue. I had the chance to make a full-size prototype on a Holzfraese at Koch-Mannes Maschinenhandel in Schweinfurt. It was cut from 18 mm plywood using a 4 mm single flute end mill at an incredible 4500 mm/min with just two cuts (9 mm depth per cut). This is not a machine for hobbyists, but it's great to try out. The wedged mortise joints work like my Doll High Chair but are flush with the surface when hammered in. I used my small handheld router to do a 6 mm roundover and sanded the parts before assembly.
