Adjusting miter cuts on a saw, particularly for common angles like 45 degrees, often involves checking the blade's angle relative to the fence and making fine-tuned adjustments.
One effective way to ensure accuracy is by adjusting both the fence and blade using a speed square.
Steps for Adjusting Miter Cuts (Using a Speed Square)
According to the provided reference, a practical method involves checking the saw's angle using a speed square and adjusting accordingly. Here’s a breakdown of the process:
- Set the Saw Angle: Tilt your saw to the desired miter angle, such as its 45-degree setting.
- Position the Speed Square: Place your speed square against the saw blade at the corresponding angle (e.g., at a 45-degree angle for a 45-degree saw setting). Ensure the speed square is flat against the blade and the saw table or fence.
- Check for Gaps: Observe closely between the edge of the speed square and the saw blade. Look for any light passing through, indicating a gap.
- Adjust the Bevel: If you notice any gaps, the angle is not precisely set. To correct this, turn the bevel adjustment bolt. This bolt is typically located near the back of the saw.
- Fine-Tune Until Accurate: Continue making small adjustments to the bevel bolt and re-checking with the speed square until there is no gap between the square and the blade. This indicates the blade is set exactly at the desired angle.
This method primarily focuses on ensuring the bevel angle (the tilt of the blade) is accurate for specific settings, which is crucial for precise miter cuts, especially when joining pieces like molding or trim at corners.
Adjusting the fence is also important to ensure the material is held securely and at the correct relationship to the blade for the chosen miter angle. While the reference highlights blade adjustment, a square is also used to check the fence's 90-degree setting relative to the blade when the saw is set to 0 degrees.
By following these steps, you can significantly improve the accuracy of your miter cuts, leading to tighter, more professional-looking joints.
