My dad and I were trying to build some box joints with a simple router jig that I had built awhile ago. Needless to say, that didn’t go well at all! We both spent the better part of the day in the shop and ended with nothing but loose joints, wasted boards, and frustration.
So that evening I spent some time researching options for box joint jigs. I came across these excellent plans from Matthias over at woodgears.ca. At first I thought it would be impossible to build, but as I worked on it step by step, it really wasn’t that hard.
I’ve only built one 48 tooth gear that is meshed with a 12 tooth gear. Since it is running on a 16 TPI rod, one revolution of the large gear produces four turns of the rod, or 1/4 inch. This is a great jig and makes cutting box joints easy and fun! (Plus the gears are a lot of fun to build and they look cool in the shop!)
