I wanted to try out some box joints on my router table so spent a little time designing a jig. It struck me that I might want to do more than one size of box joints but I didn't really want to build 2 jigs. I noticed that the router bit is not centered in the table and so I could combine both a 1/4" and 1/2" jig in one. It took a few test pieces to figure out the pin system but both sides work great. The 1/4" side works best on wood that's 1/2" thick or less, though I've tried it with 3/4" with some success-just takes a lot of cleaning up afterwards.

Pics 1-3 are the jig itself
Pic 4 & 5 are PO Box door "safes" (not banks) made using the jig's 1/2" side (3/4" lumber)
Pic 6 is a frame for a bulletin board made using the 1/4" side (about 1/4" thick lumber)

I like this design as well. Are you using the miter slot at all?

TDSpade, it looks to me like he has a guide that runs the edge of the table. If it had a miter bar, it would need to be switched to use the different sides

I like the idea a lot. I'll be working on my own edition soon. I've been messing around with a TS jig, that I've scrapped because of the inconvenience of blade changes midstream. Now if I'll just get down to it, I'll have fodder for my first post.

I like that two sided aspect of your jig, very clever!

TDSpade, Ben is right. It doesn't use the miter slot, it has a guide on each side that runs along the side of the table.

Great idea!! (slapping forehead)Why didn't I think of that? Since I left off the miter slot on my router table, I now see how I can build a box joint sled. Thanks a million!!

Thanks Chris, I didn't see the guide on the other side. This is timely for me as I have been looking at different designs of box joint jigs on the web. I think this one will work for me.
