I built this box joint jig because I wanted to cut different sized box joints without a dado stack. It works really well and I have already cut over 60 boxes using it, making boxes ranging from 1/8 inch to 1/2 inch sized joints. I made this jig to fit on my cross cut sled which I built a few weeks ago (and which I made a detailed how-to video on, so anyone can build it if they want to).

For the addition, I used baltic birch for most parts, and some mahogany I had around for a wheel, handle and other small parts.

This jig works really well, you do have to count in order to get different sized joints, however it is not very difficult once you get used to it. I really like that you don’t need many parts to create this jig, it’s not a complicated build, it’s pretty easy, and it’s very useful.

I also made a very detailed video of this build including measurements and process. Please check it out if you’re interested in building one too:

Excellent way to make box joints! I also count when I make box joints on my Horizontal Mortise Machine (A Matthias Wandel’s plan build). Set up is different but the results are very accurate.
Nice work you your build!
