Mitering Moudings. One of the most troublesome things the carpenter meets with is the cutting of a spring moulding when the horizontal portion has to mitre with FIG. 181 B a gable or raking moulding. Undoubtedly the best way to make good work of these mouldings is to use a mitre box. To do this make the down cuts, B,B (Fig. 181), the same pitch as the plumb cut on the rake. The over cuts 0,0,0,0 should be obtained as follows: Suppose the roof to be a 13.42" FIG. 182 ..9 quarter pitch-though the rule works for any pitch when followed as here laid down—we set up one foot of the rafter, as at Fig. 182, raising it up 6 inches, which gives it an inclination of quarter pitch; then the diagonal will be nearly 13 inches. Now draw a right-angled triangle whose two sides forming the right angle, measure respectively 12 and 13 inches, as shown in Fig. 183. The lines A and B show the top of the mitre box with the lines marked on. The side marked A 132 12 B FIG. 183 13 inches is the side to mark from; this must be borne in mind, and it must be remembered that this bevel must be used for both cuts, the 12-inch side not being used at all. Another excellent method for obtaining the section of a raking mould that will intersect a given horizontal moulding, is given below, also a manner of finding the cuts for a miter box for same. The principles on which the method is based being, first, that similar points on the rake and horizontal parts of a cornice are equally distant from vertical planes represented by the walls of a building; and, second, that such similar points are equally distant from the plane of the roof. Representing the wall B K b FIG. 184 faces of a building by the line DB (Fig 184), and a section of the horizontal cornice by DBabcdefBab being the angle of the roof pitch, draw line aa', cc', ff', parallel to DB and intersecting the line ka', which is drawn at right angles to DB through the point B; then, with B as a center, |
