The King-Post Roof. Another method of framing a pyramidal, or circular roof, known as the "king-post method," is shown in Fig. 94. This is preferred by many workmen, as all of the rafters may be cut alike, and as all common rafters, and the kingpost, a, may be extended indefinitely above the roof as a support to a finial, or ornamental finish for the peak of the roof, (a, Fig. 95.) This shows a finial made as part of the king-post, a common met hod where a piece of wood suitable for turned work can be obtained. It can be extended also below the roof, as at b, if the connection of the rafters at the peak needs strengthening. This is generally advisable if the roof is of half pitch, or less.
