Determine the rafter angles: Hip and valley rafters are cut at specific angles to fit the roof's slope and shape. The steel square allows for accurate determination of these angles. The steel square comprises two primary parts: the body and the tongue. The body possesses a long edge called the blade, while the tongue is shorter and positioned perpendicular to the body. 3. Position the square: Place the steel square against the edge of the rafter stock (the wood piece that will be cut). Ensure that the body's blade aligns flush with the bottom edge of the rafter stock. 4. Identify the plumb or seat cut angle: To mark the plumb or seat cut angle, slide the square along the rafter until the desired angle aligns with the top corner of the rafter stock. This angle depends on the roof's pitch and specific design. Once aligned, use a pencil or marking knife to mark the angle on the rafter stock. 5. Mark the birdsmouth cut: The birdsmouth cut refers to the area where the rafter rests on the wall's top plate. To mark this cut, maintain the square in the same position as in the previous step. Determine the desired birdsmouth depth, typically specified in the framing plan, and mark it on the rafter stock by sliding the square up or down. 6. Repeat for multiple rafters: If you have several hip or valley rafters to mark, repeat the aforementioned steps for each rafter. Ensure consistency in measurements and markings to uphold accuracy throughout the construction process. It is important to bear in mind that utilizing a steel square for marking hip and valley rafters necessitates familiarity with roof framing and the specific angles involved. If you lack experience in roof construction, it is advisable to consult a professional or refer to reliable resources for guidance.
