Dave,
I first used something called Loctite "Extreme Bond"?
No matter, because that didn't work. For me, it kept coming loose when I tried to get the shaft back into the visor when the leading edge of the plate made contact with the metal sleeve inside the visor.
I filed the leading edge to give it a nice slope, and almost got it in, but finally changed adhesives.
I actually used some Walmart generic super glue, and that worked perfectly.
So far, so good, but I've only moved the visor about 5 times. We'll see if it holds up.
I'm guessing that the shape of the aluminum plate might be important. I was careful to cover the entire flat area and file the edges to follow the shape of the shaft at the edges, thinking that this might mimimize shearing stress on the adhesive.
