One good tip; when using CA on any hardwood or plywood, dust the wood first with a bit of soda (like used in the kitchen). Hardwoods are usually slightly acidic and CA does not like anything acid. The soda tends to neutralize it and lets the CA make a much better than normal bond on hardwood or plywood. You can also use the soda to fill up a small void or make a fillet. Just do not expect to be able to sand it smooth; it will be as hard as a rock and almost unsandable.
