Well I got a functional router! The new wedge grips so tight I almost didn’t get it back out. (Hot tip: Safety Is Your Concern.)
After looking at your plane and watching a plane making video, I decided to transfer the mortise layout to the end of the plane body. Then I scribed in the thickness of the chisel blade. I cut a new wedge blank and transfered the scribed layout to the wedge. That got me a lot closer to the shape needed. The rest was just fitting and refinement.
I also cut a dowel to plug a hole I drilled through on the first mortise attempt. Really need to work on my aim.
Obviously it needs more shaping and prettying up. But she lives and is ready to dance!
Thanks for the help!
