This clock holds a secret chamber under the lid, and its construction involves a few secrets as well. The case is made from 1/2"-thick cherry plywood, which isn’t available at most lumberyards.

You can simply make your own by gluing together two pieces of 1/4" cherry plywood.

Another secret to building this clock is to glue the moldings to the plywood case material first and then miter the parts on the table saw as a single piece. It simplifies the building and sure beats mitering all the moldings individually.
