In the previous post I mentioned I was going to discuss the rabbet detail at the edge of the doors where they meet. To create the overlapping rabbeted edges without adding any stock and making it appear as an afterthought, the rabbeted edge profiles are formed from the door stiles themselves. Since the inner door stiles have been designed to be, in this case 1 1/2 inches wide, rabbeting one or the other would reduce this width of stile by the width of the rabbet and in the process cause the door stiles to look a bit off. I also want the right door to overlap the left door with the assumption that the right hand door is typically the first one to be opened.
The techniques I use is to create the left door middle stile at 1 3/4 inches and keep the right door middle stile at 1 1/2 inches. The overlapping, complementary rabbets, once created, will leave both stiles at 1 1/2 inches width. Design dilemma solved!
The primary reason to have these overlapping rabbets is both a form and function issue. Wood doors tend to expand and contract with seasonal change, although much less with this frame and panel design, but nonetheless there is a small gap that narrows and widens where the doors meet. The overlapping rabbet handles this very well, providing wood behind the small gap resulting in no glaring gap between the doors and the doors interlock. These two features justify this extra step. In the photo above the rabbet detail can be seen and the door stile widths are once again of the same width, or at least the visible parts are.
