The Woodfather designed a simple, flexible, easy to use box joint jig – his project is here. I made a clamping fence for it that, in my opinion, works better than just using a clamp to hold the workpieces.

I made the fence wider than Mario’s plans call for and mounted a cross piece on threaded rods that are screwed into the fence back of the fence piece. Two shop made knobs tighten this cross piece against the workpieces.

I’ve also posted a video of the fence on YouTube.

Questions or comments are welcome.

Nice clamp setup very similar to the one I made for my finger joint jig and they work well.
You may want to consider a sandpaper strip added to the clamp bar and another clamping rod closer together for narrower pieces as the bar will tend to bend .

Thanks Klaus. I had the sandpaper trick in mind if I have any slippage. Another location for the right side rod would be almost no trouble at all. Probably do that tomorrow.

Nice jig HuckD. This should be a big helper in the shop! I like the idea Klaus and you had with the sandpaper. Nothing better than having a good grip on you work.

It needs a clamp in front for sure. I find that I must be hyper focused with the woodfather jig to keep my joinery tight.

Nicely done Huck. Your jig is about as simple as it can be.

Earl,
Thanks for the idea. I also built the Woodfathers single blade jig and added a fence. My fence is a bit bulkier and makes it difficult to see where you are cutting. I think I am going to modify the clamp on mine similar to your clamp. I added a screw clamp from the left to keep the spacer blocks tight and I find that this works quite well.

George it’s still difficult to see the blade but I got used to that quick enough. I started out using a spreader but found I was putting so much pressure between the two end pieces I was concerned about pushing them apart. Mine’s not made of the best materials. By using the clamp on the right I can get the “teeth” really tight. I was completely out of 3/4 ply by the time I started on the fence. I doubled up on the <1 />ve been using my scraps on recent projects. :)

I like the simplicity of this jig and that there is almost no setup required. I like the idea of using whatever is at hand and that sometimes means that you have to adapt from the original design. But as long as it works, that is ok. Seeing how others adapt gives me new ideas and that is what makes our hobby so interesting.

Nice job, I really like that style of clamping across the front, I think I’ll update my plan soon to include that.
Hope it works well for you!

Cheers, Mario

Mario, it is working well. I’d be happy if you included it in your plans.
