Thanks for all the suggestions...
I went to the local welding shop and picked out a nice piece of steel for $10. Then I went to the Home Depot Aviation Department and got a piece of plywood to embed the plate. The plywood worked out better than particle board because my router cut down to one layer, which became easy to cut out. What a mess however.
The bad part was that I HAD to buy another tool.

I purchased a grinder to smooth out the steel. As you see in the picture, I need to smooth it out a bit more.
I bought some cheap red and green spray paint to highlight the areas outside the riveting area. OK, so I got carried away. Someday, someone will look into my workshop and say, "what the heck is that thing?".
The idea was to move the skin over the plate as needed. I'm wondering if I should instead cut the panel down and move the plate?
Last weekend I finally got back to working on the other elevator. I figure I better work on that first before ordering the replacement, just in case I need to re-order BOTH elevators.
Anyway, here's a picture of the monstrosity.
