What happens here
To convert a roof pitch (e.g., a 4/12 pitch) to a specific degree setting for a chop saw, first use the speed square to find the degree equivalent of the pitch. Align the speed square's pivot point on the edge of the board and rotate it until the 'Common' scale reads the desired pitch (e.g., '4' for a 4/12 pitch). Then, read the corresponding number on the 'Degrees' scale. For a 4/12 pitch, this typically corresponds to approximately 19 degrees. Set your chop saw's miter angle to this degree (19 degrees), and make your cut. This allows for quick and accurate repetitive cuts without needing to mark each board individually.
Goal: Accurately set a chop saw angle based on a given pitch measurement.
