Q: How do you use a steel square to lay out a birdsmouth cut?: To use a steel square to lay out a birdsmouth cut, you will first need to determine the dimensions required for the cut. A birdsmouth is a notch or cutout typically made on the top edge of a rafter to allow it to sit securely on a wall or other supporting structure. Here's a step-by-step guide on how to use a steel square for this purpose: 1. Measure and mark the desired depth of the birdsmouth cut on the rafter. This is typically determined by the thickness of the supporting structure it will be resting on. 2. Position the steel square on the rafter, aligning the longer leg (blade) with the edge of the rafter. Ensure that the shorter leg (tongue) extends beyond the width of the rafter. 3. Slide the square along the rafter until the desired length of the birdsmouth cut is reached. The point where the blade meets the rafter edge should align with the mark indicating the depth of the cut. 4. Hold the square firmly in place and use a pencil or a scribe to trace along the edge of the tongue. 5. With the square still in position, rotate it so that the tongue is now aligned with the edge of the rafter, and the blade is extending beyond the width of the rafter. 6. Slide the square along the rafter until the desired length of the cut is reached, ensuring that the point where the tongue meets the rafter edge aligns with the mark indicating the depth of the cut. 7. Once again, hold the square firmly in place and use a pencil or scribe to trace along the edge of the blade. 8. The resulting lines should form an L-shape on the rafter, representing the outline of the birdsmouth cut. 9. Using a saw, carefully cut along the traced lines to create the birdsmouth. Take care to stay within the lines and maintain the desired dimensions. By following these steps, you can effectively use a steel square to lay out and cut a birdsmouth, ensuring a precise fit for the rafter onto the supporting structure.
