Essential Tools for Angled Cuts

Before diving into specific methods, make sure you have these essential tools:

• Table Saw: A reliable table saw with a smooth-running miter gauge slot.
• Miter Gauge: Your saw’s standard miter gauge. (Or a high-quality aftermarket gauge.)
• Measuring Tools: A protractor, angle finder, or combination square for precise angle setting.
• Safety Gear: Safety glasses, hearing protection, and potentially a dust mask.
• Clamps: For securing workpieces, particularly when using jigs.
• Push Sticks/Paddles: Always use these to keep your hands safe and away from the blade.

Method 1: Using the Miter Gauge for Simple Angles

The miter gauge is the easiest way to make angled cuts table saw for smaller pieces.

How to Set Up Your Miter Gauge

1. Loosen the Locking Knob: Find the knob on the miter gauge that locks the angle setting. Loosen it so you can move the gauge’s head.

2. Set the Angle: Use a protractor, angle finder, or even a combination square to set the miter gauge to the desired angle. Most gauges have degree markings, but it’s always best to double-check.

3. Tighten the Locking Knob: Once the angle is set, tighten the locking knob securely.

4. Test Cut: Always make a test cut on scrap wood to verify the angle before cutting your final piece.

Safe Cutting Practices with the Miter Gauge

• Firm Grip: Hold the miter gauge firmly against the table saw surface and in the miter slot.
• Slow and Steady: Push the miter gauge and workpiece through the blade at a slow, controlled pace.
• Use a Push Stick: If your hand gets within 6 inches of the blade, use a push stick to complete the cut.
• Avoid Kickback: Never force the wood. If it binds, stop and reassess.
• Blade Height: Set the blade height just above the thickness of your workpiece.

Limitations of the Miter Gauge

• Small Pieces: The miter gauge is best for small to medium-sized pieces.
• Accuracy: The accuracy of the miter gauge is limited by its design. Play in the miter slot and the gauge’s own construction can introduce errors.
• Support: It doesn’t provide much support for large or long pieces.

Method 2: Creating a Miter Saw Alternative with a Table Saw Sled

A table saw sled for angles is a jig that slides in the miter slots. It offers greater stability and precision angle cutting than the miter gauge alone. It is the ideal miter saw alternative.

Building a Basic Table Saw Sled

1. Base: Cut a piece of plywood or MDF large enough to support your workpieces.

2. Runners: Cut two pieces of hardwood (or use UHMW plastic) that fit snugly in your table saw’s miter slots. Glue and screw these to the underside of the base, ensuring they are parallel to each other.

3. Fence: Attach a fence to the front edge of the sled, perpendicular to the runners. This is your zero-degree reference. Use glue and screws to secure it.

Adding an Adjustable Angle Feature

1. Pivot Point: Mark a point on the sled where you want the angle to pivot.

2. Rotating Platform: Cut a smaller piece of plywood or MDF to serve as the rotating platform.

3. Angle Scale: Use a protractor or angle finder to create an accurate angle scale on the sled base.

4. Securing the Angle: Design a system to lock the rotating platform at the desired angle. This could involve T-tracks and knobs, clamps, or even a simple bolt and wing nut.

Using the Sled for Angled Cuts

1. Set the Angle: Adjust the rotating platform to the desired angle.

2. Secure the Workpiece: Clamp the workpiece to the rotating platform.

3. Slide the Sled: Carefully slide the sled through the blade.

4. Consistent Pressure: Apply consistent downward pressure to the workpiece and sled.

Advantages of Using a Sled

• Accuracy: Sleds are more accurate than miter gauges, especially for repeatable cuts.
• Stability: The larger base provides better support for workpieces.
• Safety: Sleds keep your hands further away from the blade.
• Repeatability: Setting an angle is easily repeatable.

Disadvantages of Using a Sled

• Time: Building a sled takes time and effort.
• Space: Sleds take up storage space.
• Capacity: Sleds may limit the size of workpieces you can cut.

Method 3: Mastering Bevel Cuts on the Table Saw

Bevel cuts table saw are angled cuts made by tilting the saw blade, not the workpiece. This method is ideal for creating angled edges.

Setting the Bevel Angle

1. Locate the Tilt Mechanism: Find the lever or knob on your table saw that controls the blade’s tilt.

2. Loosen the Lock: Loosen the lock that secures the blade angle.

3. Set the Angle: Use the saw’s angle scale or a protractor to set the blade to the desired bevel angle.

4. Tighten the Lock: Secure the blade angle by tightening the lock.

Safe Practices for Bevel Cuts

• Blade Height: Adjust the blade height so it protrudes slightly above the workpiece.
• Featherboards: Use featherboards to keep the workpiece tight against the fence.
• Push Sticks: Always use push sticks to guide the workpiece through the blade.
• Direction of Feed: Feed the workpiece against the rotation of the blade.
• Dust Collection: Ensure your dust collection system is working effectively, as bevel cuts tend to produce more dust.

Advantages of Bevel Cuts

• Versatility: Bevel cuts can create a wide range of angled edges.
• Consistent Angle: The angle remains consistent throughout the cut.
• Large Workpieces: Bevel cuts are suitable for larger workpieces.

Disadvantages of Bevel Cuts

• Dust: Bevel cuts can generate a lot of dust.
• Blade Clearance: Ensure you have sufficient clearance around the blade to avoid obstructions.
• Limited Angle Range: Most table saws have a limited bevel angle range (usually 0-45 degrees).

Advanced Table Saw Angle Cutting: Compound Miter Cuts

Compound miter cuts involve cutting both a miter angle and a bevel angle simultaneously. These are common in projects like picture frames and crown molding. Achieving compound miter cuts requires both skill and precision.

Calculating Compound Angles

Calculating the precise angles for compound miter cuts can be complex. Online calculators and woodworking books can help.

Setting Up for Compound Cuts

1. Miter Angle: Set the miter gauge or sled to the calculated miter angle.

2. Bevel Angle: Tilt the saw blade to the calculated bevel angle.

3. Secure Workpiece: Secure the workpiece firmly to the miter gauge or sled.

4. Test Cut: Make several test cuts on scrap wood to fine-tune the angles.

Tips for Accurate Compound Cuts

• Sharp Blade: Use a sharp blade to minimize tear-out.
• Slow Feed Rate: Feed the workpiece slowly and steadily.
• Consistent Pressure: Apply consistent pressure to the workpiece.
• Double-Check: Double-check all angle settings before making the final cut.

Troubleshooting Common Problems

• Inaccurate Angles: Double-check your measurements and angle settings. Ensure your miter gauge or sled is properly calibrated.
• Tear-Out: Use a sharp blade and a zero-clearance insert. Score the cut line with a utility knife before sawing.
• Kickback: Ensure the workpiece is supported and fed in the correct direction. Use featherboards and push sticks.
• Vibration: Make sure your table saw is properly secured to the floor or a stand. Check the blade for balance.

Safety First

Always prioritize safety when working with a table saw. Cutting angles accurately is important, but not as important as preventing injury.

• Wear Safety Glasses: Protect your eyes from flying debris.
• Use Hearing Protection: Table saws are loud and can damage your hearing over time.
• Disconnect Power: Always disconnect the power before making adjustments or changing blades.
• Stay Focused: Avoid distractions and concentrate on the task at hand.
• Don’t Overreach: Position yourself so you can comfortably reach the controls and workpiece.
