Lots of vids about cutting box joints. But someone needs to do one on how to do the calculation to ensure the pins all end up even, instead of one end pin being narrower than the other. Everyone skips over that important point.

[@rwgreene999]

where did you get that tablesaw jig? That's something I need.

[@thewoodsmithstore]

if you are referring to the miter gauge being used in the video along with the Box Joint Cutter Set, it's the Incra I-Box, which you can purchase by clicking here... thewoodsmithstore.com/product/incra-i-box/#fullProdDesc

There is also a video to view once you click on that link that shows you easy setup and use of the Incra I-Box

Make a 10 inch set for deeper cuts on thicker stock, such as a 2x4's, and I'll buy it.

My Freud's box joint cutter set has a very small notch sticking up after I cut mine causing a gap in my finger joint. It is hard to notice but after putting them together it causes a gap.

I saw the photos of the cuts your box joint cutter set made and we're all a bit stumped on what might be the cause. It's as if one of the blades is smaller in diameter than the other. The only other possible cause that I can think of would have to do with the arbor (shaft) on your table saw. If there is an area on the arbor that is smaller in diameter than the rest of the arbor, it could allow one of the blades to drop down into the the low spot and then the blade would be running off-center, which would effectively make a deeper cut than the mating blade. This could give you a notch like you show. The third possibility is simply a defective blade set. You might try reaching out to Freud and see if they have any insight on what might be causing this.

Thanks for the video and as a result I ordered the set and the Incra jig. Can you add a shim between the two blades like on a dado stack to widen the cut bigger than 3/8"?

[@thewoodsmithstore]

I don't think Freud recommends that. You might be able to widen it by a thousandth or two, but there isn't enough overlap on the teeth to go much wider than 3/8"

??? Which brake cartridge do you use with this set???

[@thewoodsmithstore]

We used a dado cartridge with this set. Thanks for asking!

[@WarmFLBear]

What "jig" / miter are you using?

[@thewoodsmithstore]

That is the Incra I-Box. It's a great jig for box joints. We may feature it in another video in the future because we've had a lot of interest in it.
