The joining of the molding is to be what is known as coping. This is done in the following manner: The molding is left projecting beyond the inside end of the mortises, as shown in [Fig. 107, B]. The molding on the rails is to be cut at an angle of 45 degrees. This is done by taking the templet used in Exercise No. 6 and placing it on the rail as shown in [Fig. 107, C], and cutting the molding with a chisel down to the tenons. This will give the line by which the coping is to be cut. The cutting is done by using the gouge, [Fig. 109], one that is ground on the inside preferred; cut the coping deep enough to receive the molding which projects beyond the mortise, [Fig. 107, B]. The line which will show at the joining of the molding on the face of the exercise will look like a miter joint. This joint has the advantage of always being close, for no amount of shrinking or swelling will open it.

After all cutting is done, put together and see if all joints fit; having tenons cut as shown in [Fig. 107, C]. This allows room for wedges.
The wedges are cut with a back-saw out of a piece of board of the same thickness as the tenons. [Fig. 110] shows how this is to be done.
If the joints are all satisfactory open them enough to allow the glue brush to go between the shoulders and the stiles; put a little glue on both sides of the tenons and drive together, putting clamps or large handscrews on to bring the joints up close; dip the points of the wedges in glue and drive them between the ends of the mortise and the edges of the tenon; remove the clamps and let the glue set before smoothing the sides of the work. The door, when the wedges are driven and clamps removed, will look as shown in [Fig. 111].
