Table Saw Safety: Your Top Priority

Table saw safety is the most important thing to consider before you even think about woodworking projects. Table saws are powerful and can cause serious injuries if not used correctly.

Essential Safety Gear

Always wear the right safety gear:

• Safety Glasses: Protect your eyes from flying debris.
• Hearing Protection: Table saws are loud and can damage your hearing over time.
• Dust Mask or Respirator: Sawdust can be harmful to your lungs.
• Close-Fitting Clothing: Avoid loose clothing that could get caught in the blade.
• No Gloves: Gloves can reduce your feel and get caught, increasing risk.
• Steel-Toed Boots: Recommended for foot protection in the workshop.

Key Safety Rules

• Never reach over a running blade. Always turn the saw off and wait for it to stop completely before reaching near the blade.
• Use push sticks and push blocks. These tools keep your hands away from the blade.
• Stay focused. Avoid distractions when using a table saw.
• Inspect your wood. Look for knots, nails, or other imperfections that could cause kickback.
• Never force the wood. If the wood is binding, stop and figure out why.
• Keep the blade sharp. A dull blade requires more force and increases the risk of kickback.
• Never cut freehand. Always use the fence or a miter gauge to guide your cuts.
• Disconnect the power. Unplug the saw before making any adjustments or changing the blade.
• Keep your workspace clean. A cluttered workspace can lead to accidents.
• Know your saw. Read and understand your saw’s manual.

Spotting and Preventing Kickback

Kickback is a dangerous situation where the wood is thrown back towards you by the blade. Here’s how to prevent it:

• Use a riving knife or splitter: These devices prevent the wood from pinching the blade.
• Use anti-kickback pawls: These pawls grip the wood and prevent it from being thrown back.
• Feed the wood at a steady pace: Don’t push too hard or too slowly.
• Make sure the fence is parallel to the blade: A misaligned fence can cause the wood to bind.

Table Saw Setup: Getting Ready To Cut

Proper table saw setup is key to safe and accurate cuts.

Checking Blade Alignment

• Power off and unplug the saw.
• Use a precision square to check that the blade is 90 degrees to the table. Adjust if needed.
• Check that the fence is parallel to the blade. Use a ruler or a specialized alignment tool.

Installing the Riving Knife or Splitter

The riving knife or splitter is a crucial safety device.

• Make sure the riving knife/splitter is the right size for your blade.
• Install it according to the manufacturer’s instructions.
• Ensure it moves freely and is properly aligned.

Adjusting the Fence

The fence guides the wood during ripping wood.

• Lock the fence securely in place.
• Double-check the measurement between the fence and the blade.
• Make sure the fence is straight and free of debris.

Setting Blade Height

The blade height affects the cut quality and safety.

• For most cuts, the blade should be about ¼ inch above the wood.
• For thicker wood, you may need to raise the blade higher, but never expose too much blade.

Deciphering Table Saw Techniques

Mastering basic table saw techniques is essential for safe and accurate table saw cuts.

Ripping Wood

Ripping wood is cutting wood along the grain.

1. Set the fence to the desired width.
2. Use a push stick to guide the wood past the blade.
3. Keep the wood tight against the fence.
4. Maintain a steady feed rate.
5. Never reach over the blade.

Crosscutting Wood

Crosscutting wood is cutting wood against the grain.

1. Use a miter gauge to guide the wood.
2. Hold the wood firmly against the miter gauge.
3. Move the miter gauge and wood smoothly through the blade.
4. For wider pieces, use a crosscut sled for better support and accuracy.

Using the Miter Gauge

The miter gauge is used for making angled cuts.

1. Set the miter gauge to the desired angle.
2. Lock the miter gauge securely in place.
3. Hold the wood firmly against the miter gauge.
4. Feed the wood smoothly through the blade.

Working with Push Sticks and Push Blocks

Push sticks and push blocks are essential safety tools.

• Use push sticks for ripping narrow pieces of wood.
• Use push blocks for crosscutting and for applying downward pressure.
• Always keep your hands well away from the blade.

Table Saw Blade: Selecting the Right One

The table saw blade you choose affects the quality of your cuts.

Types of Blades

Blade Type	Use
Rip Blade	Cutting wood along the grain (ripping).
Crosscut Blade	Cutting wood against the grain (crosscutting).
Combination Blade	General-purpose cutting.
Dado Blade	Creating wide grooves or rabbets.
Thin Kerf Blade	Requires less power, reduces waste.
Plywood Blade	Minimizes tear-out when cutting plywood.

Choosing the Right Blade

• For ripping, use a rip blade with fewer teeth.
• For crosscutting, use a crosscut blade with more teeth.
• For general-purpose cutting, use a combination blade.
• For specific materials like plywood or laminate, use a blade designed for that material.

Changing a Table Saw Blade

1. Disconnect the power.
2. Raise the blade to its highest position.
3. Use the wrenches provided with your saw to loosen the arbor nut.
4. Remove the arbor nut, washer, and old blade.
5. Install the new blade, making sure the teeth are pointing in the correct direction.
6. Replace the washer and arbor nut, and tighten securely.
7. Lower the blade and test the saw before using it.

Table Saw Jigs: Enhancing Safety and Accuracy

Table saw jigs can improve both the safety and accuracy of your cuts.

Types of Jigs

• Crosscut Sled: Provides better support and accuracy for crosscutting.
• Miter Sled: Allows you to make precise angled cuts.
• Tapering Jig: Used for cutting tapers.
• Dado Jig: Helps you make accurate dado cuts.
• Tenoning Jig: Used for cutting tenons.

Building Simple Jigs

Many useful jigs can be made from scrap wood.

• A simple crosscut sled can be made from a piece of plywood and two runners that fit into the miter slots.
• A tapering jig can be made from two pieces of wood hinged together.

Using Jigs Safely

• Make sure the jig is securely attached to the saw.
• Use clamps to hold the wood in place.
• Keep your hands away from the blade.

Executing Common Table Saw Cuts

Here’s a breakdown of how to perform some common table saw cuts.

Ripping Boards to Width

1. Measure and mark the desired width on the board.
2. Adjust the fence to the marked width.
3. Turn on the saw and slowly feed the board through, keeping it tight against the fence.
4. Use a push stick to guide the board past the blade, especially for narrow pieces.

Crosscutting Boards to Length

1. Measure and mark the desired length on the board.
2. Place the board against the miter gauge.
3. Turn on the saw and push the miter gauge and board smoothly through the blade.
4. Ensure the miter gauge is set at 90 degrees for a square cut.

Cutting Dados and Rabbets

1. Install a dado blade set.
2. Adjust the blade height to the desired depth of the dado or rabbet.
3. Adjust the fence to the desired width of the dado or rabbet.
4. Make multiple passes if needed to achieve the desired width.
5. Use a backing board to prevent tear-out.

Making Tapered Cuts

1. Build or purchase a tapering jig.
2. Adjust the jig to the desired angle of the taper.
3. Secure the workpiece to the jig.
4. Guide the jig along the fence, feeding the workpiece through the blade.
5. Ensure the jig is stable and securely held against the fence throughout the cut.

Applying Knowledge To Woodworking Projects

Now that you understand the basics, here are some simple woodworking projects you can tackle.

Simple Woodworking Projects
