Hello Ron.  I was just about to call you out for not posting any progress reports.  The trim should hold the slight warp in check, once the glue has dried.  Try not to get any on the finish side of the plywood so it doesn't seal the grain before staining.  If any glue does make it there, wipe quickly with a wet rag to remove it.  The trim will flex with the plywood, and should pull flat agin once screwed back onto the cabinet.  To keep any glue off of the grille cloth put strips of wax paper around the edges of the top before screwing it to the cabinet.  Fold it over the grille cloth, then attach your trim.  Any glue seepage will end up on the wax paper, which shouldn't adhere to the trim.  Take care, Gary
