I wanted to see if it was possible to cut a dovetail without trying to engrave the pin slope. I have read about the chisel method, but that relies on a visible undercut of the pin, which also weakens it.
I did some modeling and calculations using Fusion 360, and used a trapezoidal wedge to lift one edge of the joint to 10 degrees, using the cutout board as a placement fixture. I also calculated the cut focus heights and entered them individually for each cut. Then I flipped the part, raised the other edge, and cut again.
Here’s the setup:
And the result:
So you can get it to work, but only for short lengths (or else the piece goes too high), and it’s not easy or realistic. But it was fun to try.
