I think it he was going to make bandsaw boxes cut out of single solid blocks, sectioning and gluing to get an outside shell with a back and an inner hollow drawer or two. If well done (or lucky) it's difficult to see the glue lines and for the uninitiated to imagine how they are made.

Mark, depending on where you live and your environment 12% is a reasonable number for air-dried wood. In my air conditioned/heated shop blocks get a little drier but not much. (I don't heat or cool to typical urban american standards.) I would also consider them ready for use. Fortunately the width of the bandsaw blade kerf always seems to provide a little extra clearance.
