Hexagonal Rafters. In cutting the rafters for a hexagonal roof, the same formulas and methods may be used as described in the previous topic. The first pair of rafters may be cut the same as a pair of common rafters of the same dimensions; but the cheek cuts of the second and third pairs may be made as illustrated in Fig. 93.

Fig. 93. - Apex of a Hexagonal Roof.

Notice that if the rafters are placed as shown at a, the cheek cut upon one side of the rafter will be larger than that upon the other. Many workmen prefer to cut a rafter of the sort at b, where it will be seen that one rafter has but one cheek cut, which brings equal cheek cuts upon the other rafter.
