A digital tool assists in determining the correct dimensions and angles for a notch, often called a “kerf,” cut into a rafter. This notch allows the rafter to rest securely on a horizontal beam, typically a wall plate or beam. Users input values such as rafter slope, beam width, and other relevant parameters. The tool then calculates the necessary cut dimensions, ensuring a precise and structurally sound joint.
Accurate notching is crucial for roof stability and load-bearing capacity. Historically, carpenters relied on manual calculations and layout tools. This digital approach streamlines the process, reducing the risk of errors and improving efficiency. It also aids in material optimization, minimizing waste. The transition to digital methods represents a significant advancement in carpentry and roof construction, ensuring greater precision and structural integrity.
