Based on my experience with epoxy, plywood, and fasteners when
attempting to use same for boat building, when drilling a hole thru
plywood, I always use the following:
1)Drill a 3/4" hole for 1/4" bolts, 1-1/4" hole for 1/2" bolt, etc.
2)Tape bottom of hole shut and fill proud with micro-balloon thicked
3)When cured, sand flush, then drill thru hole in epoxy for bolt.
4)Paint as required.
