What is the conventional angle used for directional notches in face cuts?

The conventional angle used for directional notches in face cuts is typically 45 degrees. This angle is optimal because it balances the reduction of wood fibers that hold the tree while still allowing for effective control over the direction of the fall. A 45-degree notch effectively guides the tree as it begins to fall, ensuring that it drops in the desired direction.

When employing this angle, the notch should be deep enough to allow for adequate wood removal, which is crucial for a clean and safe cut. The design promotes stability and helps avoid any sudden changes during the felling process by directing the weight of the tree down through the cut. Overall, using a 45-degree angle is essential for maximizing safety and precision in tree felling operations.
