Figure 49 Detail of the back of the kast illustrated in fig. 43. (Photo,
Gavin Ashworth.) The maker of this kast used hollow, round, and rabbet
planes without fences to produce the "pitched plank" cornice
molding. The transitions between the hollows and rounds are evident in
the large ogee elements. The straight edge at the bottom of the cornice,
sometimes misidentified as a chamfer, is actually the surface of the plank
and identifies the angle at which the molding is pitched off plumb.
