Acknowledging the Table Saw: What it is and Why It Matters

A table saw is the heart of many woodworking shops. It’s a versatile machine for ripping wood, crosscutting wood, and creating various joinery. Its precision and power make it indispensable for both beginners and experienced woodworkers. This guide helps you understand how to safely and effectively harness that power.

Deciphering Table Saw Components

Before you start cutting, knowing the parts of your table saw is crucial.

• Table: The flat surface where you place the wood.
• Blade: The circular saw blade that does the cutting.
• Arbor: The shaft that holds the blade.
• Motor: The power source that spins the blade.
• Fence: A guide that runs parallel to the blade, used for ripping wood.
• Miter Gauge: A guide that slides in a slot, used for crosscutting wood at angles.
• Blade Guard: A safety cover that protects you from the blade (always use it when possible).
• Riving Knife/Splitter: A metal piece behind the blade that prevents the wood from pinching the blade and causing kickback.
• Anti-Kickback Pawls: Toothed devices that prevent the wood from being thrown back towards you.
• Dust Port: A connection for a vacuum to collect sawdust.

Component	Function
Table	Supports the wood being cut.
Blade	Performs the cutting action.
Fence	Guides wood for straight, parallel cuts (ripping).
Miter Gauge	Guides wood for crosscuts, especially at angles.
Blade Guard	Provides a physical barrier for safety.
Riving Knife	Prevents kickback by keeping the kerf open.
Anti-Kickback Pawls	Prevents kickback by stopping the wood from moving backward.
Dust Port	Connects to a dust collection system.

Prioritizing Table Saw Safety: A Non-Negotiable Aspect

Table saw safety is paramount. A moment of carelessness can lead to serious injury. Here are essential safety rules:

• Always wear safety glasses: Protect your eyes from flying debris.
• Use hearing protection: Table saws are loud and can damage your hearing over time.
• Never reach over the blade: If you need to adjust something, turn off the saw and wait for the blade to stop.
• Keep your hands away from the blade: Use push sticks and push blocks to guide the wood, especially when cutting small or narrow pieces.
• Never force the wood: If the wood is binding, stop the saw and figure out the problem.
• Be aware of kickback: This is when the wood is thrown back towards you at high speed. Use the riving knife and anti-kickback pawls to prevent it.
• Inspect wood for knots and imperfections: Knots can cause the wood to bind and kickback.
• Don’t wear loose clothing or jewelry: These can get caught in the blade.
• Never use a table saw when tired or distracted: Focus is key to table saw safety.
• Unplug the saw when changing the blade or making adjustments.
• Make sure the blade is sharp and appropriate for the material.
• Familiarize yourself with the owner’s manual: This will provide specific safety information for your saw.

Avoiding Kickback: A Key to Safety

Kickback is a dangerous event. The work piece can get pinched by the blade, and the blade can throw it back towards the operator at a high speed. Here are key factors that can help prevent it:

• Use a riving knife: The riving knife is essential to prevent the wood from pinching the blade. Make sure it’s properly aligned with the blade.
• Use anti-kickback pawls: These prevent the wood from moving backward.
• Feed the wood at a steady pace: Don’t force it, but don’t hesitate.
• Don’t stand directly behind the blade: Position yourself to the side to avoid being hit by kickback.
• Use feather boards: These hold the wood against the fence and prevent it from lifting.

Mastering Table Saw Techniques: Ripping and Crosscutting

The table saw excels at two primary cuts: ripping and crosscutting.

Ripping Wood: Cutting with the Grain

Ripping wood means cutting parallel to the grain. Here’s how to do it safely and accurately:

1. Set the fence: Measure the distance from the blade to the fence to determine the width of the cut. Lock the fence securely in place.
2. Adjust the blade height: The blade should be high enough to cut through the wood, but not excessively high. A good rule of thumb is to have the blade teeth extend about ¼ inch above the wood.
3. Use a push stick: For narrow pieces, always use a push stick to guide the wood past the blade. Keep your hands well away from the blade.
4. Feed the wood at a steady pace: Don’t force it, but don’t stop either.
5. Maintain pressure against the fence: This will ensure a straight cut.
6. Complete the cut: Push the wood all the way past the blade.
7. Have an outfeed support: As the cut piece leaves the table, it will need support. A second person can help, or you can use an outfeed table.

Crosscutting Wood: Cutting Against the Grain

Crosscutting wood means cutting perpendicular to the grain. This is usually done with the miter gauge or a crosscut sled.

1. Use the miter gauge or crosscut sled: Place the wood against the miter gauge or sled.
2. Adjust the angle (if needed): Set the miter gauge to the desired angle.
3. Hold the wood firmly against the miter gauge or sled: Keep your hands away from the blade.
4. Push the miter gauge or sled through the blade: Use a smooth, steady motion.
5. Complete the cut: Push the miter gauge or sled all the way through the blade.

Advanced Table Saw Techniques

Once you’re comfortable with basic ripping and crosscutting, you can explore more advanced table saw techniques.

• Cutting Dadoes and Rabbets: Use a dado blade set or multiple passes to create grooves (dadoes) or notches (rabbets) in wood.
• Cutting Tapers: Build a tapering jig to safely and accurately cut tapers on your table saw.
• Cutting Curves: While not its primary function, you can create gentle curves by making multiple shallow cuts and then sanding smooth. It is much safer to use a bandsaw for this task.
• Making Moldings: Specialized molding heads and blades can be used to create decorative moldings.

Table Saw Jigs: Enhancing Accuracy and Safety

Table saw jigs are invaluable tools for improving accuracy, safety, and efficiency.

Crosscut Sled: Precision Crosscuts

A crosscut sled is a platform that slides along the table saw’s miter slots. It provides excellent support and allows for precise, repeatable crosscuts.

• Benefits: Safer than using the miter gauge alone, especially for small pieces. Provides more support for wider boards. Allows for perfectly square cuts.

Miter Saw vs. Table Saw: A Side-by-Side Comparison

Feature	Miter Saw	Table Saw
Primary Use	Crosscuts, angled cuts	Ripping, crosscutting
Portability	More portable	Less portable
Capacity	Limited by blade size	Limited by table size
Accuracy	Good for angled cuts, less so for long rips	Excellent for straight rips, good crosscuts
Safety	Relatively safe	Requires more attention to safety

Feather boards: Keeping the Wood Secure

Feather boards are devices that hold the wood firmly against the fence or table, preventing it from lifting or moving during the cut.

• Benefits: Improves accuracy and safety. Reduces the risk of kickback.

Tapering Jig: Cutting Angles Precisely

A tapering jig allows you to cut consistent tapers on your table saw.

• Benefits: Allows for precise and repeatable tapers. Safer than trying to cut tapers freehand.

Choosing the Right Table Saw Blade: Optimizing Performance

The table saw blade is the cutting tool, so selecting the correct one is important. Different blades are designed for different purposes.

• General Purpose Blades: Suitable for most ripping and crosscutting tasks.
• Ripping Blades: Designed for fast, efficient ripping. Have fewer teeth with larger gullets for chip removal.
• Crosscut Blades: Designed for clean, smooth crosscuts. Have more teeth with smaller gullets.
• Dado Blades: Used for cutting wide grooves (dadoes). Come in sets with multiple blades and chippers.
• Plywood Blades: Designed to minimize tear-out when cutting plywood and other veneered materials.
• Metal Cutting Blades: Used for cutting non-ferrous metals such as aluminum and brass. (Ensure your saw is rated for metal cutting.)

When choosing a table saw blade, consider the following:

• Blade Diameter: Match the blade diameter to your saw’s specifications.
• Arbor Size: Ensure the blade’s arbor hole matches your saw’s arbor size.
• Tooth Count: Higher tooth counts for smoother cuts, lower tooth counts for faster cuts.
• Tooth Grind: Different tooth grinds are optimized for different materials and cutting tasks.
• Kerf: The width of the cut made by the blade. Full kerf blades are more stable, while thin kerf blades require less power.

Table Saw Fence: Ensuring Straight Cuts

The table saw fence is essential for straight, accurate cuts. Here’s what to look for:

• Solid Construction: The fence should be made of sturdy material and be able to lock securely in place.
• Accurate Measurement: The fence should have a clear, easy-to-read scale for setting the cutting width.
• Easy Adjustment: The fence should be easy to adjust and lock in place.
• Parallel Alignment: The fence must be parallel to the blade to ensure straight cuts. Use a precision square to align the fence.

• Inspect the power cord and switch: Make sure they are in good condition.

Frequently Asked Questions (FAQ)

Q: How often should I sharpen my table saw blade?

A: It depends on how often you use the saw and what types of materials you’re cutting. A good rule of thumb is to sharpen the blade when it starts to produce rough cuts or requires more force to push the wood through.

Q: Can I use a table saw to cut metal?

A: Only if the blade and the saw are specifically designed for metal cutting. Using a wood-cutting blade on metal can be very dangerous.

Q: How do I prevent tear-out when cutting plywood?

A: Use a plywood blade with a high tooth count, score the cut line with a utility knife before cutting, and use a zero-clearance insert.

Q: What is a zero-clearance insert?

A: A throat plate with a very tight opening around the blade. This reduces tear-out by supporting the wood fibers as the blade exits the cut.

Q: Is it safe to freehand cut on a table saw?

A: No. Always use the fence, miter gauge, or a jig to guide the wood. Freehand cutting is dangerous and can lead to kickback.

Q: What are the signs that my table saw needs professional servicing?

A: Unusual noises, excessive vibration, difficulty adjusting the fence or blade, or burning smells are all signs that your saw may need professional servicing.
