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!

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.
