I spent some time creating the rabbets for the frame and panel backs. These rabbets run along the inside rear of the side panels as well as along the backs of the tops and bottoms for each of the cabinets. The rabbets for each of the tops and bottoms are stopped, this to create a rectangular recess in which to fit the frame and panel back. I typically use the router to create these rabbets and I need to square the ends of the stopped rabbets to fit the vertical rabbets which run in the side panels. A picture is worth a thousand words here and the picture at the left provides the best explanation for what I am accomplishing.
Once I have completed this I was anxious to test fit the components of each of the cabinets to physically see what the cabinet begins to look like. I assembled the sides and tops and bottoms for each of the cabinets carefully marking each component for both orientation and to associate the component with the correct cabinet. You can see I am a big believer in liberal use of markings. The issue isn't any confusion while one is in the studio but rather when one comes back after a day or two and then trying to remember which part goes where.
Everything is fine at this point and next I temporarily clamp each of the cabinet components together. This temporary clamped state will remain for a while as I now begin to take exact measurements for the next set of components. I begin with the cabinet doors. These doors will also be veneered and I need to determine the size of each of the substrates while allowing for bake-ins and top and bottom edging. I also need to allow for the door rabbets, the ingenious method of having cabinet doors close onto themselves through the use of a lip and rabbet. This temporary clamping also allows me to begin measuring the frame components for the frame and panel at the rear of each of the cabinets.
I also now have the opportunity to better match the ambrosia maple door fronts with the ambrosia side panels, while seeking continuity in grain, graphics and also colour variations. The top and bottom edge treatment I have not decided on yet, this will likely be a very small chamfer around the periphery of the cabinet. There is an alternative approach to all this.... to create the doors first and build the cabinet round the doors. I've never done it this way, but it's like any other process, a matter of becoming familiar with it...much like the tails vs. pins approach to dovetail joinery. Next I create the substrates for the veneered door panels.
