After making the Steltman chair, I reflected on how to adapt parts for the 1F, particularly the joinery. The more I learn, the more the gaps in my knowledge of the fundamentals of designing for CNC are evident 
As a learning exercice, I decided to manufacture some of 50 digital joints for wood as documented by Jochen Gros. Mr Gros shared DXF files but, as I use Fusion 360, I decided to create parametric models. I also milled the CNC joints from scrap wood.
I’ll share the results in the forum, hoping to help some fellow 1Fers. I started with the Secret Fingertips Tenons which Mr Gros describes as:
The secret version of the Fingertip Tenons Joint leads to a rabbet at the front edge of the assembled joint. From a design-oriented viewpoint, this rabbet is an interesting design detail on furniture. For traditional wood and furniture construction the rule was not to let a joint show, however compli- cated its execution might have been. But today, in the age of industrial furniture construction with its invisible connectors in the form of dowels and la- mellos, times have changed. The demonstratively shown joints are a sign for the quality of furniture made by a craftsman.
