Rh from each intersection of both miter lines of the rake moulding. Points of intersection in the stretchout may be determined by following each extension line from its source in the profile to a correspondingly numbered line in the stretchout. The miter cuts of the pattern are drawn by connecting the points of intersection. As in the case of the side patterns for the conductor head,

one pattern will suffice for both rake moulds, but they must be formed in pairs for assembling.

Another line of stretchout is now drawn at right angles to the base line of the horizontal moulding as shown in Fig. 261. Upon this line should be laid down the spacing of the entire profile including the point A. Measuring lines are drawn through each point at right angles to the line of stretchout.
