everything fit perfectly and so fudge for the room not being square. The lerni cope probably derives from the use of a coping saw as the main tool for this job.

Today any cut with a shaper across the end grain is known as a cope cut.

The Frame and Panel Door

The illustration at right shows a simple frame-and-panel door, consisting of a wood panel surrounded by relatively narrow strips of wood. Tspically the strips at the sides of the door run from the extreme top to the extreme bottom and are called the stiles. The strips running horizontally at the top and bottom, between the stiles, are called the rails. Think of the rails of a split rail fence and you will never get the two mixed up.

The stiles and rails have a groove running around the inside edge into which the panel is inset. The panel is sized smaller than the opening to allow for some wood movement side to side. In traditional joinery a tenon would be cut on the end of the rails and a corresponding mortise would be cut in the stiles. The result was a very strong door. The Shakers, with typical overkill, even cross-pinned the tenon with two wood pins at each corner to add mechanical strength, in case the glue tailed.

The reason for using a mortise and tenon joint was to bring plank (or face) grain glue areas into contact, for as we all know, glue has little strength on end grain. Our stick/cope panel door set emulates this time honored method by coping a short tenon on the ends of the rails, which then fits within the panel groove. While this does not provide the glue area of a true mortise and tenon, it does give sufficient strength for most applications.

So. in a stick and cope door sel there are two distinct cutter assemblies. One assembly mills a profile on the inside edges of the stiles and rails—this is the slicking set. The other assembly copes a profile matching lhat left by the sticking operation on the ends of the rails—this is the coping sel (Fig. I A).
