used, make another plumb mark on the other side of the raf-

ter just opposite of the bottom plumb mark (see Figure 10).
STEP 4. CUTTING HIP RAFTER PATTERN: With your saw

set at 45°, cut the top plumb cut, making sure the top

bevels are opposite for opposite rafters. Setting the saw

at 45° automatically gives the plumb cut and the side cut

bevel. Make bottom plumb cut on a 45° angle if miter is

used. If a bevel is not needed, set saw at 90°. The seat

notch is made with the saw at 90° (see Figures 9 and 10).

INTERSECTION OF HIPS ON RIDGE

To find the intersection points of the hip on the ridge rafter,

cut ridge one foot longer at the point where hips intersect

the ridge. With a regular length common rafter, set the seat

notch cut over the edge of the top plate, in line with the

ridge (see Figure 11). Making sure your walls are straight,

place top end of common rafter even with top of ridge.
