How to Use a Table Saw

A table saw is a versatile and essential tool in any woodworking setup. It can rip, crosscut, miter-cut, square, dado, and even apply shapes to edges of wood. However, as with any power tool, it's crucial to understand how to use a table saw correctly and safely. This guide walks you through the steps of operating a table saw.

Understanding the Parts of a Table Saw

Before we delve into the operation, let's identify the main parts of a table saw:

• Table: The large, flat surface where the workpiece rests.
• Blade: The circular saw that does the cutting. It protrudes through a slot in the table.
• Rip Fence: A guide that keeps the wood aligned for rip cuts.
• Miter Gauge: A guide used for crosscuts and angled cuts.
• Blade Guard: A safety device that covers the blade.
• Riving Knife: A thin piece of metal that prevents the workpiece from pinching the back of the blade, reducing kickback.

Safety Precautions

Before you begin cutting, always prioritize safety:

• Wear Proper Safety Gear: Use safety glasses to protect your eyes from flying wood chips. Wear hearing protection to shield from noise. Avoid loose clothing or jewelry that can get caught in the saw.
• Maintain a Clean Workspace: Keep your work area clean to prevent slips, trips, and falls. After each cut, clear away scraps.
• Use Push Sticks: When ripping narrow workpieces, use push sticks to guide the wood through the blade. This keeps your hands a safe distance from the blade.
• Check for Obstructions: Before you start the saw, ensure there are no obstructions that could interfere with the blade or your workpiece.

Setting Up Your Table Saw

• Adjust the Blade Height: Raise or lower the blade so that its topmost tooth is no more than 1/4" to 1/2" above the top of the workpiece. This minimizes exposure to the blade and reduces the risk of kickback.
• Set the Blade Angle: If you're making a bevel cut, adjust the angle of the blade. For normal cuts, the blade should be at 90 degrees to the table.
• Position the Rip Fence or Miter Gauge: For rip cuts, set the rip fence to the desired width. For crosscuts or angled cuts, set the miter gauge to the desired angle.

Making a Cut

Rip Cut

A rip cut is along the grain of the wood. Here's how to make one:

1. Set the rip fence to the desired width.
2. Start the saw and let it reach full speed before making your cut.
3. Feed the workpiece into the blade, keeping it pressed against the rip fence. Use a push stick for narrow cuts.
4. Push the workpiece all the way past the blade, then switch off the saw.

Cross Cut

A cross cut is across the grain of the wood. Here's how to make one:

1. Set the miter gauge to the desired angle.
2. Start the saw and let it reach full speed before making your cut.
3. Hold the workpiece against the miter gauge and feed it into the blade. Don't use the rip fence for cross cuts, as it can cause kickback.
4. Push the workpiece all the way past the blade, then switch off the saw.

Advanced Table Saw Techniques

Dado Cut

A dado cut is a wide, flat cut used to fit pieces of wood together. To make a dado cut, you'll need a stacked dado blade set. Here's how:

1. Install the dado blade set to the desired width.
2. Set the blade height to the depth of the dado.
3. Position the rip fence or miter gauge to the desired location.
4. Start the saw, feed the workpiece into the blade, make the cut, then switch off the saw.

Rabbet Cut

A rabbet is a two-sided cut made at the edge of a workpiece. To make a rabbet:

1. Install a dado blade set to the width of the rabbet.
2. Set the blade height to the depth of the rabbet.
3. Set the rip fence to the width of the rabbet.
4. Start the saw, feed the workpiece into the blade, make the cut, then switch off the saw.

By now, you should have a basic understanding of using a table saw. Remember, practice is key. As you gain more experience, you'll be able to make more complex cuts and use your saw more efficiently. Always prioritize safety and you'll find that a table saw is an invaluable tool in your woodworking arsenal.
