A much simpler method to fixing the tang hole is to overbore it with a drill and then drive a hardwood dowel into it with some good wood glue. Drill your new pilot hole, then screw the screw in.
I've done this one a few occasions (some on firearms) and it's worked extremely well - very cheap and very durable. Just a thought anyway.
