This is small one, a 1/2” box joint jig for the router table based on the mlcs woodworking box joint jig

Base and fence are 3/4” mdf, rail is quinilla hardwood

I had this made a while ago, but had to replace the previous rail made with pine and slightly thinner than 1/2” which made the joints not as good as they should, this time I got the rail right on spot :)

thanks for watching!

interesting method. I like that it is sort of based on its own little platform and doesnt need to be registered to a miter gauge.

Do you adjust the position of the rail by tapping it or do you align it against the table fence and use its adjustment?

I’ve always wondered about the speed of doing box joints on a router table compared to TS. Can you get through each pin with one pass? how about blowout problems?

AaronK:

The router fence appears but is not actually used with the jig, too lazy to move it out of the way to take the pictures hehe.

You adjust the distance from the router bit to the rail (the rail sits on a groove made on the base) then clamp the base to the router table, 1/2” drill bit works great as spacer here (would change if you are going with 1/4”, 3/8”, etc. rail size would have to match too).

And yes you can do each pin with only one pass, as long as the pieces are clamped firmly to the fence guide and the spacing is done properly.

About the blowout, the fence guide serves as a backer to avoid it, and you actually go thru it a little, just added another picture to show this.

mafe: sure, you’ll make it look awesome I guess ;)

gotcha. it looks like its also really easy to do lots of pieces at once, so each one would back up the one before it. I also like that its really easy to set up with a drill bit.

Great idea! I’m going to try this. It’s a lot simpler than the conventional designs and a lot lot less clumsier too.
