Matthias Wandel inspired this box joint jig. I had some wormwood veneer and covered a chunk of 3/4 Baltic Birch ply for the base. From there I choose to run a parallel set of screws joined by a chain drive set of Cogs. I used brass bearings and tapped a piece of red oak on each side to tether the carriage to the drive system. I made the track out of cypress complete with handcut the dovetails. I then made the transmission next and used Matthias’s design which I really like allot (thanks Matthias!) The carriage was next. It was really a few happy mistakes that ended up with the racing stripes. I have adapted this pattern in many of my projects. A few gears cut on the CNC and I was in business.

This was a challenging project and a whole bunch of fun. My hope was to have a very functional tool that had a bit of style as well.

It’s a fantastic piece of engineering, isn’t it?
I’m afraid my approach is a bit more basic, but it suits me:

Cheers

I’m entirely new to this, and I love the instructional video further down in the comments.
Steve, in your video as you attach the guide to the base of your jig, you scrape the screws through something.
Is that some kind of ball of wax? glue? What is the purpose there?

@Cerestes
It’s the remains of an old candle. It helps to drive the screws in, putting less stress on the screw and the driver. It’s particularly useful when screwing into hard timbers like maple, but I do it with everything.

Dedalo,

Love my incra- double dovetails are a great joint. I guess I was just impressed with Matthias’ site. he has a video where he finger joints a dowel, at that point I was hooked on this jig. The incra is pretty fast if you get in a grove but its real advantage is it is completely repeatable. This jig is FAST!! I didn’t think about it before I built it, but that is my favorite part of it.

As far as why I built it, thats a tough one. I have a short list of things I am going to build before I pass on (my bucket list!) This jig, and a CNC machine are done. I still have a wooden gear clock, and the grand daddy of them all, a boat, yet to finish. All in time. I suppose you could say it was because I am an old mountain man and, well, the jig was there….

Thanks for looking, this site is awesome!

Steve
