I have a bunch of things on my list to build where I can use box joints to add a little to the builds. So, last week I decided to build a box joint jig. I wanted one that had the flexibility to cut multiple sizes with the same size blade and repeatable results. And since I am too frugal to buy one, I wanted to build it myself. I looked at many videos on youtube with different types and finally settled on this one. The plans were downloaded from the Ed Stiles “Box Joint Jig” video on youtube. So far I am really pleased. Just make sure that your blade is actually a multiple of 1/16” since this jig is based on using a 16 tpi threaded rod. I still need to round over the edges and put on a coat of poly. The last picture show the fit using my dado stack configured for 1/4”.

Thanks for the posting!
This incorporates some concepts that fill in some gaps I’ve had in planning some jigs I want to make for table saw/router this year.

I built this a while back and it was a fun build and works great.
Check my projects for it.
There’s a few tips that helped me but yours is done and looking good.

Job well done! I’m sure it will give you many years of service. I am also a big fan of box joints, in fact I love them so much that I’ve used them on all of my jewelry boxes lmao. For many the dovetail is the choice for fine boxes but I’ve always been more attracted to the box joint. It’s so semetrical and balanced, not to mention all the glue joint surface area. True it is lacking in the locking mechanism area but who needs that in a box lmao

Also if you’ve ever been curious on an easy way to get perfectly semetrical fronts/back & sides in your boxes. Just rough cut all for sides the same width but all 1in or so oversized. After all your joints are cut rip to final deminsions so your fronts/backs match and sides match with sides.

Not sure if you already knew that trick but I figured I’d save you some research.

I built this same jig a while back and really really like it. The best box joint jig I have found so far. Great work!

Hi Jeff
Looks very impressive,good build.Just wondering ,if the box joints are say 1/2” do you have to crank the handle 4 times for each box joint if it’s based on 1/16ths?

a1Jim,
When cutting 1/4” joints with a 1/4” dado stack, you make a cut and then turn the crank 8 times.
If making 1/2” joint using a 1/4” dado stack you would make a cut, turn the crank 4 times to make the rest of the 1/2” cut, then 12 turns to start the next cut. Ed Stiles does a great overview of how it works, so watch his video on YouTube when you can.

I made a similar jig a few years ago. Did you do anything to remove slop in the threaded parts? I added springs and rubber washers and it still causes repeatability problems sometimes.

I have not had any problem with slop in the carriage. I used metal washers and double nuts on each side of the threaded rod to lock it in place between to side supports. It does not move at all.
