Box joint jig with micro adjustment

I saw someone post this a couple of weeks ago, realized I had almost everything to make it already, so decided to go ahead and make one. I downloaded the plans, got some hardware I needed and started working on it. A couple of modifications I made was the use of 1/4-28 rod and nuts instead of #10-32 since I had some of the hardware on hand and would have to order the inserts anyway, couldn’t find them at lowes or ace hardware. Another modification was adding a miter bar to the bottom that pivots on a bolt and is secured with a screw, allowing the bar to be rotated so it is easier to store (pic 4). The jig works well, and the micro adjustment is a great feature. Thanks for looking.

Great work. I’ve been looking at these for a while, so between yours and the one that was posted a couple of weeks ago, it might be time to just do it!

Looks great. I also have the plans for one of these set ups. Does it work ok without a dado blade?

I have the same question as Jim (JR45)... My (cheap) table saw doesn’t take a dado blade, so if this works….
Looks great!

Well, I guess my pictures are a bit misleading. I took the pictures before putting in the dado set to test it out. It made some great 3/8” box joints. Now to your question, it will not work as is with only a single kerf blade. There are two metal brackets that allow for adjustment of the pin size. The ones I got were 0.166” together, bigger than a standard 0.125” blade kerf.

The plans even say that it can create joints 1/4” – 13/16”. But you could modify the brackets to make them an 1/8” or use just one piece of metal that is 1/8”. I would just get a piece of metal that is already 1/8” thick, I know lowes has some stock like this. I think it can be done if you can’t use a dado set, but it will just be harder to get the joints set up. The jig can also be used on a router table, if you have one with a miter slot. I hope this helps.

This is really great work and very useful, can you tell us where the plans can be found?

Here is where I purchased my set of plans, but I’m sure you can search for plans also.
