Box Joint Jig

This is a box joint jig that I made to help me with my tool cart build. I made the jig after watching Laney Shaughnessy’s YouTube instructional video that he posted. It takes him about 1 hr to make, but it took me about 3 days to complete. I’ll post a link at the bottom.

I just use some 3/4 and 1/4 plywood and some walnut scraps that I had laying around. I got the hardware from Lowe’s. I used 1/4-20 bronze furniture bolts and plastic styled wing nuts. I also made several interchangeable pieces which allow me to use this jig for joints from 1/4” to 3/4”.

The hardest thing for me was to make the keystocks the same size as my dado blade. I made them to the exact fractional dimensions and it did not work out too well. I didn’t realize that my dado wasn’t designed to give me exactly 1/4” – 3/4” dados, so I made template and then cut the keystocks to fit. I may have been able to adjust the jig so that I could use the original keystocks that i made, but with my lack of knowledge and experience I just re-did them just to make sure.

Nice work. I like that idea. Mine is a dedicated 1/4”. I have thought about making something adjustable like this, but my ideas were too complicated ;-))

I’m pretty sure I’d need 3 days+ to make that jig. And I’m not sure how well my finished product would work. That said, I’m going to cop-out and buy the incra ibox. LOL.
Nice job though. I really liked the drawers you made.

Is it possible to make this jig work without a dado blade I.e. just a standard sawblade? Alistair

Nice work, again! Like you, I tend to need way more time than the pros or a well skilled amateur. However, I’d rather take my time to make the project up to my standards or level of satisfaction.

Alistair I don’t think it would. You would probably need one of those gear advanced types to do that.

I think Alistair could set one up with a kerf width index pin, then do a lot of nibbling after the first notch was established. Probably be better to use a router if no dado blade available.

I think you could use it with no dado blade. You would need to make the pin the width of your saw blade. Cut the first notch to width then you could cut side to side by moving the stock across the pin. IF the first notch were cut too wide or too small all the rest would be the same. Certainly not as convenient as a dado blade.

Great job, I have been meaning to make antother one as mine is worn out and beat up…. I like this set up…. I like the video and thought how he did both peices of wood at the same time was interesting. I was taught a different way. I like his better. Thx for sharing and enjoy….

Great job! I think I have always hesitated to make a similar jig like this because I was not confident in setting up the key stocks properly. Thanks for sharing the video, too.
