My joints have been basic to say the least up until now,dowel, pocket hole, mitre, butt, lap and half lap… you get the idea! so to extend on my repertoire, I decided to go with Mario Cappellano (thewoodfather) and his basic jig, I won’t be doing them often, so don’t need anything fancy, but not having a dado set up was the decider on choice.

It only took a couple of hours to make, from scraps, and an angle bracket I had lying around, the latter acting as the guide pin. I made it out of 3/4” Ply and some left over 2×4, I built it to make 1/2” fingers.

I then did a test joint, to be honest it is a bit on the tight side, it did take some persuading to interlock, but that’s probably because I didn’t do anything to tidy up the cut edges, a minor adjustment might be needed but not much, I am certainly pleased with it.

As you can see, the joints are ever so slightly proud, but that was down to the blade height, and could have soon been sanded level, but there are no gaps!

I think the tight joints now are better than loose. Using solid woods the joint might break if pressured too much, that veneer sample went okay. You can always file a bit away from each joint that fits snug. Adding filler to each one would look bad.
Ive always wanted to make one for smaller box joists. Keep procrastinating !

You are right, I rather file a bit away, than try to alter the jig and wreck it! Thanks

—Adding this jig to my project queue, along with the DIY jointer, cross cut sled and the wedge corner clamps. Seriously, when does one get time to do woodworking with all the jigs? :D

By the way, how did you cut the fingers off? Dado blade?

Thanks for the comments Omar, I get the odd project done between jig building, my problem being that I moved to Colombia from Spain just over three years ago, I had to sell every last nail before moving, a lifetimes collection of tools, so I was starting again from scratch, I can’t afford to replace all my tools, so I look for anything that will help make life easier, and in the main that means jigs!

Everything you see on this project was either cut on the table saw with a single blade or on the band-saw, I haven’t got, and never have had a dado blade, whether I will ever get one, I’m not sure, they are handy, but I am happy doing things the way I know how, it might take a bit longer, but hey, I’ve got the time! :) If you watch Mario’s YT vid, I constructed this in the same way he did.

I usually cut half lap joints with a single blade, too, using my table saw cross cut sled. It, s a pretty versatile tool, the table saw. Whuch is why invested big bucks on a dewalt contractor saw.
