Some experiments with a laser-cut mortise and tenon joint:
Elegant design!

Ooooo…
This makes me want to run out and design something right now. Tapping that wedge in just looks so satisfying!
Thank you for sharing!

I think you and I might be a lot alike…I felt the same way when I saw that.

interesting… don’t have an application for it just yet. but hey one never knows.
I had an idea that needs an SVG of an American flag. searched around here and found the perfect one.
so I figure I’ll be searching for this thread some day in the future.

The wedge, mortise and tennon may well be man’s oldest piece of joinery, but I sure like this take on it.
I really wonder how this would work in acrylic?

Anything to use less glue is a plus.

Ooh! I wonder if this would be even more permanent with the addition of @dan’s serrated tabs
Gonna have to figure out something to test it with

I was thinking the same thing!
The write-up mentions something similar as a possible future evolution.

I’m pretty sure light serrations would help in certain materials. Like acrylic.

If anyone else wants to give this a shot before I get around to it…

Okay, I had to know. You know, for science.
Medium draftboard: Holds but the pin tends to go off center and split. Ify
1/8 Baltic Birch: Holds but the pin tends to go off cent and split. Ify
1/4 plywood: didn’t work at all as the kirf was too big
Thick draftboard: Pin goes off center (is this just me?) but shows the most promise, nice joint after a little tweaking
1/4 acrylic: snapped, so total failure
Thick cheery proofgrade: Best of the bunch! the outer plys hold everything together and it would be totally possible to make a great joint with this. For the win!

Thanks for sharing your testing @markevans36301.

I think you could play around with the wedge angle to find the happy medium between a nice tight fit and enough stress to crack the acrylic. Since the acrylic isn’t going to compress much, it wouldn’t take much of a wedge at all do do it.
