You’re working with a 7/12 Pitch and half your overall span is 4 Feet.
The irregular Pitch is 8/12, and 16-inch On-center spacing is main-
tained on both sides. Complete the following steps:

(1) Find the length of the common rafter; 
(2) Reset calculator to 16-inch On-center spacing;
(3) Enter the Irregular Pitch; find the length of the adjoining 

“Irregular” Hip (or Valley) and the cut angles; 

(4) Find the incremental jack adjustment and the jack lengths on

the “Irregular” Pitch side (16-inch On-center spacing); 

(5) Find the cut angles;
(6) Find the incremental jack adjustment and the jack lengths on

the “Regular” Pitch side (16-inch On-center spacing);

(7) Find the cut angles.
