Building this jig:    • How to build my Box Joint Jig  
I have been wanting to build a box joint jig for woodworking joinery for a long time. In this video I show off my homemade arduino-controlled box joint jig for the table saw.
The structural parts of this jig consist of wood whereas the motion is controlled and executed by cheap electronic components like the ones used for hobby CNC-machines. The brain of this finger joint jig is an arduino nano, which controlles a big stepper motor via a cheap stepper motor driver. The turning motion of the stepper motor is translated ito linear motion using a ball screw. This definitely makes this a screw-advanced box joint jig. The ball screw could be substituted using a piece of threaded rod or allthread for a more economic approach.
This box joint jig features a clever little detail which makes the joints produced come out always perfect.
