Thanks for the great replies. Very informative.

One other question:

If a CA hinge comes out of socket, what is the best way to repair this, assuming the remaining 3 or 4 are still holding? Removing the old glued in hinges would be a challenge. Then, where do you mount the new hinge? Is there a way to clean out the old sockets in prep for new hings or must you cut new slots in difference locations?
