Figure 38.—Erecting the curb plate:

1, end rafters of middle section; 2, wall plate; 3 end wall posts of middle section; 4, ridgepole; 5, small intermediate purlin immediately page 50above wall plate; 6, curb plate: a, the level of the middle of the curb plate is fixed by the measure of the distance (7) between the ridgepole and the small intermediate purlin immediately above the wall plate. One end of a measured line (8) is held against the end of the ridgepole, and the line is stretched obliquely downwards in the middle long axis of the house. The ends of the curb plate are placed in position below the wall plate ends and the middle is raised or lowered until the end of the taut measuring line touches its upper surface. The curb plate is then restrutted in position with about 7 struts (9) which may be cut to exact length for propping under the curb plate or left long and tied against the side. The short struts are tied in the same way as the collar beams to the purlins, but with fau bark and with not so many turns. The correct level of the curb plate is important, for if too high (sisi) or too low (tautau) it is justly regarded as poor work. b, Side view from inside, showing the position of the curb plate end below the end of the wall plate on the outer side of the end wall post of the middle section; c, side view from outside, showing the curb plate below the wall plate and temporarily lashed (10) to the end rafter of the middle section. Later a wall post is erected in position (11) to permanently secure the curb plate.
