Is it a cast metal or stamped sheet metal?

Cast iron.

It's sounding like the recommendations a

1. JB-Weld, epoxy paint, or something similar, followed by
sanding it down (probably with a full sheet of paper spray-glued to a
flat piece of glass or some such).
2. Call a local machine shop and see what they can do, or
3. Relax my sphincter, and accept that I can't get square edges
.... which would be acceptable if I had a decent jointer, but I was
relying on my WWII blade to make up for that ...
