Fathoming Table Saw Safety

Table saws are powerful tools, and table saw safety should always be your top priority. Every year, woodworking shops see injuries from improper table saw use. Take the time to learn the right techniques and follow these guidelines to protect yourself:

• Always wear safety glasses: Protect your eyes from flying debris.
• Use hearing protection: Table saws can be very loud.
• Wear appropriate clothing: Avoid loose clothing, jewelry, or anything that could get caught in the blade.
• Never reach over the blade: Always turn off the saw and wait for it to stop completely before reaching over the table.
• Keep your hands away from the blade: Use push sticks and push blocks to guide the wood.
• Never force the wood: If the wood is not feeding smoothly, stop and check for obstructions.
• Be aware of kickback: Kickback occurs when the wood is pinched by the blade and thrown back towards the operator. Use appropriate techniques to prevent kickback, such as using a splitter or riving knife.
• Stay focused: Avoid distractions while operating the saw.
• Inspect the saw before use: Check the blade, fence, and other components for damage.
• Unplug the saw when making adjustments or changing the blade.

Table Saw Setup: Getting Ready to Cut

Proper table saw setup is critical for both safety and accuracy. Follow these steps before you start cutting:

1. Position the Saw

Place the table saw in a well-lit area with plenty of space to move around. Make sure the floor is level and free of obstructions.

2. Inspect the Blade

Check the table saw blade types for any damage, such as missing teeth or cracks. A damaged blade can be dangerous and produce poor cuts. Ensure the blade is appropriate for the material you plan to cut.

3. Install the Blade

• Unplug the saw from the power outlet.
• Raise the blade to its highest position.
• Use the wrenches provided with your saw to loosen the arbor nut.
• Remove the nut, washer, and blade.
• Install the new blade, making sure the teeth are pointing in the correct direction of rotation (usually indicated by an arrow on the blade).
• Replace the washer and nut, and tighten securely.
• Lower the blade to its desired cutting height.

4. Adjust the Fence

The table saw fence adjustment is crucial for accurate cuts.

• Ripping: For ripping (cutting wood along the grain), position the fence parallel to the blade at the desired width. Lock the fence securely in place.
• Crosscutting: When crosscutting with table saw (cutting wood against the grain), use a miter gauge in the miter slot.

5. Set the Blade Height

The blade height should be set so that the teeth extend no more than ¼ inch above the workpiece. This reduces the risk of kickback and improves cut quality.

6. Install the Splitter or Riving Knife

The splitter or riving knife is a crucial table saw safety feature that helps prevent kickback. It sits behind the blade and keeps the kerf (the cut made by the blade) open, preventing the wood from pinching the blade.

7. Attach the Blade Guard

The blade guard provides a physical barrier between your hands and the blade. Always use the blade guard unless it interferes with a specific cutting operation (such as cutting dadoes).

8. Test the Setup

Before cutting your project material, test the setup on a piece of scrap wood. This allows you to check the accuracy of the fence and blade height and ensure that the saw is running smoothly.

Essential Table Saw Techniques

Mastering a few basic table saw techniques will enable you to handle most woodworking projects safely and effectively.

Ripping Wood on Table Saw

Ripping wood on table saw means cutting a board along its length, parallel to the grain.

1. Set the fence to the desired width.
2. Place the edge of the wood firmly against the fence.
3. Turn on the saw.
4. Feed the wood slowly and steadily into the blade, keeping it tight against the fence.
5. Use a table saw push stick to push the wood past the blade, keeping your hands well away from the cutting area.
6. Maintain a consistent feed rate to avoid burning or kickback.

Crosscutting with Table Saw

Crosscutting with table saw means cutting a board perpendicular to its length, across the grain.

1. Place the miter gauge in the miter slot.
2. Position the wood against the miter gauge.
3. Turn on the saw.
4. Push the miter gauge forward, guiding the wood through the blade.
5. Keep the wood firmly against the miter gauge throughout the cut.
6. Use a table saw push stick for small pieces or when your hands are close to the blade.

Using a Table Saw Push Stick

The table saw push stick is an essential safety tool. It allows you to safely guide the wood through the blade while keeping your hands at a safe distance.

• Types of Push Sticks: There are different types of push sticks available, including straight push sticks, L-shaped push sticks, and push blocks. Choose the type that is most comfortable and effective for you.
• Using a Push Stick: Place the push stick against the back of the workpiece and apply pressure to push it through the blade. Keep your hand on the push stick, not directly on the wood.

Using a Table Saw Push Block

A table saw push block is similar to a push stick, but it is wider and provides more surface area for pushing larger pieces of wood. It’s especially useful when ripping wood on table saw.

• Using a Push Block: Place the push block on top of the workpiece and apply downward pressure while pushing it through the blade. Keep your hands on the push block, not directly on the wood.

Table Saw Blade Types and Their Uses

Choosing the right table saw blade types is essential for achieving clean and accurate cuts. Here are some common types:

Blade Type	Description	Best Use
Combination Blade	Has both ripping and crosscutting teeth, a good all-around choice.	General purpose cutting of wood.
Ripping Blade	Has fewer teeth with larger gullets for efficient waste removal when ripping wood on table saw.	Cutting wood along the grain.
Crosscut Blade	Has more teeth with smaller gullets for a smooth, clean cut when crosscutting with table saw.	Cutting wood across the grain.
Dado Blade Set	A set of blades and chippers used to create wide grooves (dadoes).	Creating dadoes and rabbets.
Plywood Blade	Has a high tooth count and special tooth geometry to minimize splintering when cutting plywood and veneers.	Cutting plywood, veneers, and other thin sheet materials.
Metal Cutting Blade	Designed for cutting non-ferrous metals like aluminum and brass.	Cutting metal. Important: Only use a blade specifically designed for metal on your table saw.

Leveraging Table Saw Jigs

Table saw jigs are specialized tools that improve the accuracy and safety of certain cuts. They help you repeat cuts consistently and keep your hands away from the blade. Here are a few common types:

Miter Sled

A miter sled is a platform that slides in the miter slot and supports the workpiece during crosscuts. It provides greater accuracy and stability than using the miter gauge alone.

• Uses: Making accurate angled cuts, cutting small pieces, and creating tenons.

Tenoning Jig

A tenoning jig holds the workpiece vertically and allows you to make precise tenons (projections that fit into mortises) for joinery.

• Uses: Creating tenons for strong and accurate joints.

Tapering Jig

A tapering jig allows you to cut tapers (gradual reductions in width) on your wood.

• Uses: Creating tapered legs for tables and chairs.

Featherboard

A featherboard is a safety device that holds the workpiece firmly against the fence, preventing it from lifting or drifting during a cut.

• Uses: Improving accuracy and safety when ripping wood on table saw.

Troubleshooting Common Table Saw Problems

Even with proper setup and technique, you may encounter problems while using a table saw. Here are some common issues and their solutions:

• Burning: Burning occurs when the blade is not cutting cleanly and generates heat. This can be caused by a dull blade, a slow feed rate, or a misaligned fence.

  • Solution: Replace the blade, increase the feed rate, or adjust the fence.

  • Kickback: Kickback occurs when the wood is pinched by the blade and thrown back towards the operator. This can be caused by a misaligned fence, a dull blade, or improper technique.

  • Solution: Ensure the fence is parallel to the blade, use a sharp blade, and use a splitter or riving knife.

  • Splintering: Splintering occurs when the blade tears the wood fibers instead of cutting them cleanly. This is more common when cutting plywood or other thin materials.

  • Solution: Use a plywood blade, score the cut line with a knife before cutting, or apply masking tape to the cut line.

  • Vibration: Excessive vibration can be caused by a loose blade, a damaged arbor, or an unbalanced motor.

  • Solution: Tighten the blade, inspect the arbor for damage, or have the motor serviced.

Maintaining Your Table Saw

Regular maintenance will keep your table saw running smoothly and safely for years to come.

• Clean the Saw: Regularly remove sawdust and debris from the saw table, blade, and motor. Use a brush or vacuum cleaner for this purpose.
• Lubricate Moving Parts: Lubricate the fence rails, miter slots, and blade height adjustment mechanism with a dry lubricant.
• Check the Blade: Inspect the blade regularly for damage and replace it when necessary.
• Sharpen the Blade: A dull blade can be dangerous and produce poor cuts. Have your blades professionally sharpened or learn how to sharpen them yourself.
• Check the Alignment: Periodically check the alignment of the fence, miter slots, and blade to ensure accuracy.
