Ensuring Safety First

Before diving into angle cutting techniques, safety is paramount. A table saw is a powerful tool that demands respect. Follow these guidelines:

• Wear safety glasses: Protect your eyes from flying debris.
• Use hearing protection: Table saws are loud.
• Dust collection: Connect your saw to a dust collector or wear a respirator to avoid breathing in sawdust.
• Push sticks/blocks: Always use these when feeding smaller pieces of wood, keeping your hands away from the blade.
• Never reach over the blade: Turn off the saw and wait for it to stop completely before retrieving offcuts.
• Inspect your wood: Look for knots, splits, or foreign objects that could cause kickback.
• Keep the blade sharp: A dull blade is more likely to cause kickback and splintering.
• Be aware of kickback: Stand to the side of the blade, not directly behind it.

Methods for Cutting Angles on a Table Saw

There are three primary ways to cut angles on a table saw:

1. Using a Miter Gauge
2. Using a Table Saw Angle Jig
3. Tilting the Blade (Bevel Cuts)

Each method has its advantages and disadvantages, depending on the type of cut and the accuracy required.

Using a Miter Gauge for Table Saw Miter Angle

The miter gauge is a standard accessory that fits into slots on the table saw. It allows you to guide the workpiece at a specific angle relative to the blade.

Setting Miter Gauge Angle

1. Loosen the locking mechanism: Most miter gauges have a knob or lever that loosens the head, allowing you to adjust the angle.
2. Set the desired angle: Use the scale on the miter gauge to set the angle.
   • For common angles (45°, 90°), many miter gauges have detents or stops.
   • For more precise table saw miter angle adjustments, use a table saw protractor or a digital angle finder.
3. Tighten the locking mechanism: Ensure the head is securely locked in place before cutting.
4. Test the angle: Make a test cut on a piece of scrap wood and check the angle with a protractor or square.

Cutting with the Miter Gauge

1. Place the workpiece against the miter gauge: Ensure it is firmly against the fence.
2. Turn on the saw.
3. Slowly and steadily push the miter gauge forward: Keep the workpiece firmly against the fence throughout the cut.
4. Complete the cut: Push the miter gauge completely past the blade.
5. Turn off the saw and wait for the blade to stop: Then, remove the workpiece and offcut.

Improving Miter Gauge Accuracy

• Use an extended fence: Attaching a longer fence to your miter gauge provides more support for the workpiece and improves accuracy.
• Add a stop block: A stop block clamped to the extended fence ensures consistent cuts when cutting multiple pieces to the same length and angle.
• Check for play: Miter gauges can develop play in the miter slots. Use shims or aftermarket miter bars to eliminate this play.

Using a Table Saw Angle Jig

For more complex angle cuts or when you need to repeat accurate angle cuts, a table saw angle jig is an excellent investment or DIY project. This jig typically consists of a sled that rides in the miter slots and has an adjustable fence to hold the workpiece at the desired angle.

Building or Buying a Table Saw Angle Jig

• DIY Jig: Many plans are available online for building your own table saw angle jig. This allows you to customize it to your specific needs.
• Commercial Jig: Commercial jigs offer precision and convenience. They often have built-in angle scales and locking mechanisms.

Using a Table Saw Angle Jig

1. Place the jig in the miter slots: Ensure it slides smoothly and freely.
2. Adjust the fence to the desired angle: Use a protractor or angle finder for accurate angle setting.
3. Secure the workpiece: Clamp the workpiece firmly to the jig’s fence.
4. Turn on the saw.
5. Slowly push the jig through the blade: Maintain a steady feed rate.
6. Complete the cut: Push the jig completely past the blade.
7. Turn off the saw and wait for the blade to stop: Then, remove the workpiece and offcut.

Benefits of Using a Jig

• Increased accuracy: Jigs provide more support and stability, resulting in more accurate angle cuts.
• Repeatability: Jigs make it easy to cut multiple pieces to the same angle.
• Safer cutting: Jigs keep your hands further away from the blade.

Bevel Cuts on Table Saw (Tilting the Blade)

Bevel cuts are angles cut through the thickness of the wood. To make bevel cuts, you tilt the table saw blade to the desired angle.

Setting the Bevel Angle

1. Loosen the bevel locking mechanism: This is usually a knob or lever on the front or side of the saw.
2. Tilt the blade to the desired angle: Use the angle scale on the saw to set the angle.
   • For precise settings, use a digital angle finder.
3. Tighten the locking mechanism: Ensure the blade is securely locked in place.
4. Set the blade height: Adjust the blade height to the desired depth of cut.

Cutting Bevels Safely

• Consider blade direction: When tilting the blade, be aware of which direction it is tilting. Tilting the blade away from the fence is generally safer, as it reduces the risk of the workpiece being trapped between the blade and the fence.
• Use a featherboard: A featherboard helps to keep the workpiece pressed against the fence, ensuring a consistent bevel angle.
• Watch out for kickback: Bevel cuts can be more prone to kickback. Use extra caution and ensure the workpiece is firmly supported.

Making the Bevel Cut

1. Place the workpiece against the fence.
2. Turn on the saw.
3. Slowly and steadily feed the workpiece through the blade.
4. Complete the cut.
5. Turn off the saw and wait for the blade to stop: Then, remove the workpiece and offcut.

Advanced Angle Cutting Techniques

Cutting Compound Angles

Cutting compound angles involves cutting an angle on both the miter and bevel axes. This is often required for projects like picture frames, trim work, and furniture.

Using a Table Saw Angle Calculator

• Online Calculators: Several online table saw angle calculators can help you determine the correct miter and bevel settings for compound angle cuts. These calculators typically require you to input the desired angle of the corner or joint, and they will calculate the necessary settings.

Process of Cutting Compound Angles

1. Calculate the Miter and Bevel Angles: Use a table saw angle calculator or trigonometric functions to determine the required miter gauge and blade tilt settings.
2. Set the Miter Gauge and Blade Tilt: Adjust the miter gauge and blade tilt to the calculated angles.
3. Test Cut: Always make a test cut on scrap material to verify the accuracy of your settings before cutting your final piece.
4. Make the Cut: Securely hold the workpiece against the miter gauge and carefully push it through the blade.

Segmented Turning on a Table Saw

Segmented turning involves creating bowls, vases, and other objects by gluing together many small pieces of wood cut at precise angles. The table saw is used to cut these segments accurately.

Cutting Segments

1. Calculate the Angle: Divide 360 degrees by the number of segments you want in your circle. Then divide that number by two. This is the angle you need to set your miter gauge to.
2. Set the Miter Gauge: Adjust your miter gauge to the calculated angle.
3. Cut the Segments: Cut all the segments, ensuring they are all the same length.
4. Assemble the Ring: Glue the segments together to form a ring.
5. Repeat: Repeat the process to create multiple rings, which can then be stacked and glued together to form the final object.

Tips for Achieving Accurate Angle Cuts

• Use Sharp Blades: A sharp blade produces cleaner, more accurate cuts.
• Calibrate Your Saw: Regularly check and calibrate your table saw to ensure that the blade is square to the table and the fence is parallel to the miter slots.
• Measure Accurately: Use a high-quality protractor, angle finder, or digital level to measure angles accurately.
• Test Cuts: Always make test cuts on scrap material to verify your settings before cutting your final piece.
• Consistent Feed Rate: Maintain a consistent feed rate when cutting to avoid burning or uneven cuts.
• Avoid Forcing the Cut: If the wood is difficult to cut, check your blade and make sure your settings are correct. Forcing the cut can lead to kickback or inaccurate results.
• Use Support: When cutting long pieces, use outfeed supports or roller stands to help support the material and prevent it from sagging.

Troubleshooting Common Angle Cutting Problems

• Inaccurate Angles:
  • Cause: Incorrect miter gauge or blade tilt settings, play in the miter gauge, or movement of the workpiece during the cut.
  • Solution: Double-check your settings, eliminate play in the miter gauge, and ensure the workpiece is firmly supported.
• Splintering or Tear-Out:
  • Cause: Dull blade, cutting against the grain, or using the wrong type of blade for the material.
  • Solution: Use a sharp blade, cut with the grain, and use a blade with a high tooth count for fine cuts. You can also use a zero-clearance insert to reduce tear-out.
• Burning:
  • Cause: Dull blade, slow feed rate, or pitch buildup on the blade.
  • Solution: Use a sharp blade, increase the feed rate, and clean the blade regularly.
• Kickback:
  • Cause: Pinching of the wood between the blade and the fence, cutting warped wood, or not using a splitter or riving knife.
  • Solution: Always use a splitter or riving knife, avoid cutting warped wood, and use proper cutting techniques.
