Here is the cabinet from the right side. Here you can clearly see that the cabinet is made up of two carcases, one on top of the other. I did this for weight reasons; the lighter pieces are easier to move. Each cabinet sits on three legs made up of glued up pieces of poplar. The legs won't be visible & needn't be made from oak, since the poplar will easily be able to support the weight.
The base cabinet will have three pieces of oak mitered to form a "top" overhang. The upper cabinet will have a quarter round molding that will sit on top of this "top". The idea is to give the appearance that the two cabinets are one by hiding the seam between them.Google Sketchup. This is a free program that does 3D drawings. It's not a full blown CAD program, but it's a great tool for doing what are essentially three dimensional sketches using the computer. You can be as accurate with your dimensions as you want. Highly recommended. I decided that I would make all of the parts that would be in the front of the cabinet out of solid oak. These parts are the most visible parts and I want them to match. The parts that back up against the wall will be made out of oak plywood. The plywood would be stable (that is, plywood does not change width or length when the humidity changes) and so I wouldn't have to worry about wood movement for those parts. Also, since the inside parts would be visible only when the doors were opened, the ply only needs to have one good face. I also determined that the height & spacing of the interior shelves would be adjustable using shelf pins, and that I would make them from oak ply with solid oak edging rabbeted to the front edge. This would hide the plywood edges & give the impression that the whole piece was made from solid oak. So that's the cabinet! Next time, we'll talk more about the cut list.
