3. Drill Pilot HoleGet your drill ready with a small drill bit. Test with a small bit (1/8”) in a couple holes right in the center of the leg. Get out one of the screws, put it through the hole in the cup and screw it into the leg. You want it to be firm, but not so hard that you start to strip out the screw. If it seems too hard, try a slightly larger drill bit (9/64” or 5/32”) and try again. It is then usually easiest to then go around and drill the holes on all the legs. Drill at least ¾” deep.
