Box joints, also called finger joints, are a great way to join corners on a box. Not only do they add a significant amount of strength, they also look great. Especially when the box joint is made from contrasting materials. The table saw, equipped with a dado head, provides a great way to make box joints, provided you have a jig. WWGOA’s box joint jig video shows a simple shop-made box joint jig is the perfect solution to your box joint needs.
The plans for this jig can be found here.
Great to know how to adjust the jig but how did you make it from scratch? Mostly curious about the pin and space between pin and blade.
Yes, David made it from scratch. Here’s the plan that he created that should provide all of the information that you need: https://www.wwgoa.com/plan/how-to-make-a-box-joint-jig/

Some years ago, I made an elaborate—many might say ridiculously so—jig which is somewhat similar to Matthias Wandel’s screw advance box-joint jig, but varies in many ways. It does however have a gearbox facilitating a moveable carriage. I had never been able previously to escape the problem of compounding whatever original error might exist in the first cut, e.g. being a thou off in the first cut will create an error of two-hundredths in the twentieth. I just don’t know how to avoid the problem this way.
It didnt say how to make the jig
This tells how to adjust the jig but nothing about how to use it. I need to know how it’s used starting with the blanks.
Where can I get the plans for this box joint jig? The link does not show up on my iPhone.
Hi Gerard. You will need to be signed into your membership in order to view the plans.
Just a suggestion, how about making the links in the articles a little more obvious. I’m color blind and had to mouse over the article looking for my pointer to change.
Color seems like an obvious indicator but not for everyone.

HE explained how to use it, but not how it was constructed. It look simple.
The link to the jig plans is in the video description.
Understand the making of box joint jig but no mention of the making of the pin?
The pin should be made of hardwood, and should be 1/4″ wide (or whatever is the size of your dado) x 1-3/8″ long. It should be the height of your dado slot minus 1/16″.
