How did you plan on securing the vertical board?
I envisioned using some 90-degree angle aluminum stock and screwing into the bottom of the wasteboard and to a lower-not-depicted support. Vertical board then screwed to the aluminum angle stock as well.

@J.Russ I like the design. I’ve been keeping this option in mind when designing my table and wasteboard ideas to have the option to add a cutout in later for doing vertical and/or much thicker pieces.
Seems like a good idea as long as you have a way to square it up and adjust in the future as needed.
Or make the vertical surface (something like shown below) hinged so you can clamp the board to it then rotate to the desired angle.
