I was asked to build 16 boxes of various sizes that could be used for storage/display/moving. I used my CNC to cut a locking joint with one setup for each corner to minimize handling and clamping, I did not want to use fasteners of any kind. I was joining 1/2” Baltic birch plywood to 3/4” yellow poplar. I have never seen this joint anywhere and if anyone has please sent me a note. I call it the tyco joint, the cat’s name.

Kind of looks like the joint that my rubber floor mats have. Tweaked version of a dovetail joint.
Should hold good and tight.

Very cool! Never saw a joint like that but it makes me want to get a cnc router…...

I think I may have seen something similar to this, but I really like the way you did your set up and cut both pieces in one pass. Very novel indeed!

These boxes are wonderful for storage and other uses and are beautifully done.

Nice work. I don’t know that I have enough use for it but I’d love a CNC.

Its similar to some of the joints in MLSC’s Fast joint system.

Very clever joint. I pointed the Shaper Origin forum to this project; it looks like a joint that would be amenable to being cut using the SO’s Vertical Workstation. Having curved mating surfaces is ideal.
