Replacement for tired fingers. Countersink in Floxxed filled corners, (between outer and inner glass where foam core was removed), for 8-32 SS flat head mounting screws worked well. First tried a 3 flute countersink that made outside edge of Uni a bit ragged, a single flute cutter worked good. Just a dab of Flox and next day used single flute for perfect edge.
