Methods for Making Angled Cuts with Table Saw

Several methods allow you to make angled cuts on your table saw. We’ll explore each in detail:

1. Using a Miter Gauge for Table Saw Miter Cuts

A miter gauge is a common tool included with most table saws. It slides in a slot (miter slot) on the table saw and guides the workpiece at an angle across the blade.

Setting the Angle

1. Loosen the Locking Knob: Find the knob that locks the miter gauge at a set angle. Loosen it to allow movement.
2. Adjust to the Desired Angle: Use the angle scale on the miter gauge to set the desired angle. A protractor can help to be more accurate.
3. Tighten the Knob: Once you have the correct angle, tighten the locking knob to secure it.
4. Double-Check: Always double-check the angle setting before cutting. Small errors can creep in.

Making the Cut

1. Place the Workpiece: Hold the workpiece firmly against the miter gauge.
2. Keep it Firm: Maintain consistent pressure to prevent wobbling.
3. Slowly Push: Slowly push the miter gauge and workpiece through the blade.
4. Complete the Cut: Push all the way through.
5. Turn Off the Saw: Let the blade stop completely before removing the cut piece.

Pros and Cons of Using a Miter Gauge

Pros	Cons
Simple to use	Can be less accurate for small or complex angles
Comes with most table saws	Limited support for larger pieces
Good for repetitive cuts	Miter slot play can reduce precision unless compensated

2. Using a Table Saw Angle Jig

A table saw angle jig, also known as a miter sled, provides better accuracy and control than a standard miter gauge. These jigs offer a stable platform and often include features for fine-tuning angles.

Types of Table Saw Angle Jigs

• Basic Miter Sled: A simple platform that slides in the miter slot with an adjustable fence for setting angles.
• Advanced Miter Sled: More complex designs with clamping systems, fine-adjustment mechanisms, and digital angle finders.

Building a Simple Table Saw Angle Jig

You can build your own simple miter sled using plywood and some basic hardware.

1. Cut the Base: Cut a piece of plywood larger than your biggest workpiece.
2. Add Runners: Attach runners to the base that fit snugly in your table saw’s miter slots.
3. Attach a Fence: Attach a fence perpendicular to the front edge of the base.
4. Install Adjustable Angle System: Add a second fence that pivots, allowing angle adjustments. Use bolts and washers to secure it.

A bevel cut is an angled cut made on the edge of the board rather than the face. Bevel cuts are achieved by tilting the table saw blade. This method requires extra care to ensure safety and accuracy.

Adjusting the Blade Angle

1. Locate the Tilt Mechanism: Find the handle or wheel that controls the blade’s tilt.
2. Loosen the Lock: Loosen the locking mechanism to allow the blade to tilt.
3. Set the Angle: Use the angle scale on the saw to set the desired bevel angle.
4. Tighten the Lock: Tighten the lock to secure the blade at the correct angle.
5. Double-Check: Use a protractor or angle finder to confirm the angle setting.

Making the Bevel Cut

1. Adjust the Fence: Position the fence to support the workpiece securely.
2. Feed Slowly: Feed the workpiece slowly and steadily through the blade.
3. Use Push Sticks: Always use push sticks or push blocks to keep your hands away from the blade.
4. Support the Workpiece: Provide extra support for large or heavy pieces to prevent wobbling.
5. Complete the Cut: Push all the way through.
6. Turn Off the Saw: Allow the blade to stop before removing the cut piece.

Pros and Cons of Using Bevel Cuts on a Table Saw

Pros	Cons
