Moldings and beads are sometimes used to ornament work, but the chief use of the bead is to conceal open joints by the shadow it casts. An example of this may be seen in beaded wainscoting or large surfaces that are finished with matched ceiling. If the boards were put together without a beaded edge, an unsightly crack would be the result from the shrinking and swelling of the material.
Moldings are so varied in form that it would be useless to try to describe them here. The molding shown in the drawing is given for practice in the use of the molding plane.

A rabbet is generally a square corner cut out of the edge of a piece so as to lap over, or to make a place for glass, etc., as in window sash, glass panel doors, and door frames. The rabbet plane ([see Fig. 78]) is so constructed that the iron comes out flush with both sides, so that it will cut out a sharp corner or interior angle.
To cut the rabbet, the iron combination plow, beading, and rabbeting plane may be used, an illustration of which is shown in [Fig. 79].

This tool can be set up as a rabbet plane or fillister, having a fence to guide it along the side and a shoe to stop its cutting when the desired depth is reached.
The plan and end elevation of this exercise is found in [Fig. 80]. The bead plane, [Fig. 81], that is used on the edge of the exercise is known as a single quirked bead, and has a fence or guide by which it is held in position while the bead is being stuck on the work.
