Figure 21.—Shape of thatch rafter ('aso) join.

The long oblique slant (1) is commenced about 3.25 inches from the end of the rafter and run out to a point (2). Two inches from the point (2), a transverse cut (3) is made at right angles to the oblique plane of the slanting surface (1). The upper part of the oblique surface is cut to a lower plane (4) to meet the right-angled cut and forms another surface about 1.25 inches in length. In shaping the other end of the rafter, the point (5) must be on the other side to that first made. The point of another rafter (6) is shown in position for joining. The appearance of the two surfaces (1, 4) with the right-angled surface (3) is shown on the Right of the figure.
