Return to the first line which represents the opening, and add to the outside of that the width of the bead and rabbet; then from those lines mark across the face from the line which will represent the bead, and across the back from the line which represents the depth of the glass rabbet.

Prepare the shoulder lines for the saw as directed in previous work. The lines to be drawn on the edge of the rail are shown in [Fig. 89].
The shoulders on the munting are prepared in the same way as the rail. In marking the sides of the mortise and tenon use the mortise gauge ([see Fig. 73]).
Cut the mortise and the tenon as directed in previous work, using a narrow chisel to remove the chips from the mortise. The bead is to be joined so that it will appear continuous; the method of joining is called mitering. A miter is made by cutting, at an angle of 45 degrees, the pieces to be joined.
The practical man will try many methods of cutting material in order to save time. For instance, if he is to make frames where the corners are to be mitered, he will make a miter box. This box (which is not a box at all) is three pieces fastened together to form a bottom and two sides, all of which must be true before being nailed together; then by cutting across the sides in both directions with the saw at an angle of 45 degrees and square to the bottom, the so-called miter box is made, an illustration of which is shown in [Fig. 90]. Iron miter boxes are now in general use; of these [Fig. 91] is a good representation.

In the mitering of the bead, a templet, which can be made by the student, is of great service.
