I suggest drilling decent sized pilot holes as the epoxy won't have as much give as wood, and is liable to split if you let it get too hard before drilling and putting some screws in. Don't drill the holes too short.
I suggest doing that (with some grease or wax on the screws) before the epoxy fully hardens but is solid enough to retain its shape.
