Stonger Joints for a laser cutter

The common edge joint used for laser cutting is the finger joint. However the finger joint Has only the glue bond strength when force is applied perpendicularly to the surface. Like from the inside of a box out, and those edges will fail regularly. To combat that I designed a joint edge style that has a mechanical strength in combination to the chemical bond. In truth it somewhat relies on the strength of the glue joint, but the surface area of those joints are much larger, they are not covered in laser sap residue, and the force is applied directly to the glue point.

I will post some images of the joint here as well as the draw ups of it in corel when I take those picture/screen caps.

I will also post a link to the other page with the science tests once I do those. I have to make a testing apparatus first.

 Test to failure. As hard as I could pull to break a side. Bottom is multiple times stronger.
