I have a 40+ Delta Rockwell contractors TS that has grid wings. About ten years ago I got a Beismeyer fence that rests on the table. I covered the grids with Formica. Sanded the surface lightly and used contact cement. Worked well, but recently it has started to turn loose and is slightly lifted on the corners. It's getting looser. The wings are zinc or some sort of pot metal.
I suspect the tarnish has worked it's back into the joint and caused the contact cement to fail. Other than doing it over with contact cement any suggestion on a more permanent fix? Better adhesive?
