Project Information

This is the adjustable box joint jig I built last week, using the Woodsmith plans. I've been debating on whether to build one from Stumpys plans or the Woodsmith plans. I think I would have been happier with the jig from Stumpys plans but I decided to build the Woodsmith version because it looked a little easier to build and I was able to get the plans for free.

I was please with the final product. It looked sharp and worked as advertised. The directions were kinda vague in a couple critical areas but I was able to work throu it. The only advice I have for others who want to build this jig is make sure your holes are drilled really precise and that you get the L brackets exactly square. Otherwise the jig won't sit completely flat. I learned this the hard way and had to grind down my L brackets so the jig would lay flat.

I built one of those using the same plans (even ordered the parts kit). I was very disappointed in mine as the L brackets flex and move enough that my joints weren't consistent. Hope you have better luck with yours.
I'm coveting the Stumpy jig but don't think I'm talented enough to build it after looking at the plans.

I want to build one like that too. But, as a noob at woodworking it may be too complicated for me. I am going to make a simple one for now. I'll try something like that once I become a little more competent.

I don't get it. Is the thin metal piece going to be the size of the box joint? I guess I'm just used to my crude jig. Thanks for sharing.

There is actually 2 L brackets and one adjustment sets the space between the. For finger size and the other sets spacer size. I actually modified the plans slightly to make the L brackets really sturdy. The original plans call for a 1-1/2" rabbit for the material rest and the L brackets are attached to the rest. Well I went ahead and made my material rest 4" wide so the entire L Bracket can be attached securely.

I built one and the jig did just fine from the first time out. I had a bit of trouable aligning the top of all pieces level , but that I found out was my fault. The big plus about this jig that you forgot to menchion, is that it will adjust to any size that you can set your dado blade to.

Slap that blade together with what ever shims that the cut looks to be the right size for that joint, and this jig will adjust to that cut of that blade. You ar not forsed to accept just 1/4, 3/8, 1/2" made from a set guide. No fuss no mess no slop !!!!

also it's size, It gets so making all of these jigs adventually it gets to where are you going to put them all. What brand of "L" brackets did you buy, Stanleys was thicker than alot on that shelf and cost more ???
