I already have a box joint jig (http://lumberjocks.com/projects/101866) but I find it hard to setup with more than 2 pieces of wood in it. I like Mathias Wandel’s (http://woodgears.ca/box_joint/jig.html) design as it looks easy to setup and use. I have had his plans for a long time now so I decided to build it.
It is made from reclaimed pine and maple except the plywood for the base and gears which is birch ply but I already had that lying around as it was left overs from another project. I didn’t really make any changes to it except for the threaded nut used to advance the box. I used a peice of maple and threaded it (Mathias used a T-nut). I used my hammer drill to make the threads and then ran it back and forth a few times on hammer to make it a little looser. Lubed the threads with slip it from lee valley (http://www.leevalley.com/en/wood/page.aspx?p=69805&cat=1,43415,43440). This thing runs extremely smooth and works perfect.
The plans called for 2 drive gears ( a 12 and 16 tooth) but I only put a 12 tooth on it cause in one of his videos he said he primarily used the 12 tooth.

Cool! This is the first one I have seen built with Matthias’ plans, that he himself didn’t build. I just completed building a threaded rod version based on the one shown in this video:

However, I still would like to build a version of Matthias’. It’s faster to advance, that’s for sure!

Here is my design of a box joint jig and is a lot simpler to build doing away with threaded rods and gears .
This jig is easely adjusted to a cutter and fine tuning is a breeze .

Sean, I to have Mattias’ plans for this but haven’t gotten around to building it yet. I am glad you went first and worked out any kinks :). Great job.

Thanks everyone.
Jason, that is the same box jig I originally built and I like it. However I like to cut all four pieces of a box at the same time and it really isn’t suited for that. Mathias’s is quick and easy to setup and use.
Kiefer I like your design. It looks easy to use and build.
Lee, you need to build this thing. You won’t regret it.
