I have just come across this neat website listing 50 wood joints designed for cnc routing. http://flexiblestream.org/Digital-Wood-Joints-001.php
It combines traditional Japanese styles for joint design with cnc production. There is no charge for the patterns, but they would like to see what has been done with the designs. After viewing these ideas it is easy to see different ways to modify designs for my use.
I am currently in the process of scaling a miter joint for my purposes and generating cutting paths.
I would be interested in seeing if there is any interest in these wood joints and sharing ideas.
