Deciphering the Table Saw Fence: A Key Component

The table saw fence is one of the most important parts of a table saw. It’s a long, straight guide that runs parallel to the saw blade. You push wood against it to make accurate cuts. Without a good fence, getting straight, repeatable cuts is nearly impossible.

What is the Main Purpose of a Table Saw Fence?

The table saw fence purpose is simple: to guide the wood safely and accurately. It allows you to make rip cuts (cuts along the length of the wood) with consistent width. A well-adjusted fence ensures that each cut is parallel to the previous one, resulting in precise and professional-looking projects.

• Cons:
  • May not be as stable as other types
  • Can be more difficult to align perfectly

Using a Table Saw Fence: A Step-by-Step Guide

Using a table saw fence correctly is essential for safe and accurate cuts. Here’s a simple guide:

1. Measure: Measure the distance from the blade to the fence. This is the width of the cut you will make.
2. Lock: Lock the fence securely in place. Make sure it doesn’t move when you apply pressure.
3. Feed: Feed the wood slowly and steadily along the fence. Keep the wood flat on the table.
4. Maintain: Maintain consistent pressure against the fence throughout the cut.
5. Complete: Complete the cut. Turn off the saw and wait for the blade to stop before removing the wood.

Achieving Table Saw Fence Accuracy

Table saw fence accuracy is key for high-quality results. Here are some tips to make sure your fence is accurate:

1. Proper Table Saw Fence Alignment

Table saw fence alignment is vital. The fence must be perfectly parallel to the blade. If it’s not, you’ll get cuts that are not straight.

• Check: Use a reliable measuring tool, like a combination square or digital caliper. Measure the distance between the fence and the blade at the front and back of the blade.
• Adjust: Adjust the fence until the measurements are the same at both points.
• Lock: Lock the fence securely after making adjustments.
  The best way to do this is to install a device, such as the Posi-Lok Fence Alignment tool.
  

2. Regular Maintenance

Keep your fence clean and free of debris. Dust and sawdust can interfere with its accuracy.

• Clean: Wipe down the fence and rails regularly.
• Lubricate: Lubricate the moving parts of the fence mechanism to keep it working smoothly.

3. Consistent Technique

Use a consistent technique when pushing wood against the fence. Apply even pressure and avoid twisting or forcing the wood.

4. Verify Alignment

Double-check alignment after any adjustments or if you notice any inconsistencies in your cuts. It’s best practice to also check alignment periodically to avoid costly mistakes.

How to Adjust a Table Saw Fence

Knowing how to adjust a table saw fence is crucial for maintaining accuracy. Here’s a general guide:

1. Loosen: Loosen the locking mechanism of the fence. This usually involves releasing a lever or turning a knob.
2. Adjust: Move the fence to the desired position. Use the measuring scale on the saw table or a separate measuring tool to ensure accuracy.
3. Fine-tune: Use the micro-adjust feature (if available) to make small adjustments.
4. Lock: Lock the fence securely in place.
5. Verify: Double-check the alignment before making any cuts.

Aftermarket Table Saw Fence Options

If you’re not happy with the fence that came with your table saw, you can upgrade to an aftermarket table saw fence. These fences often offer improved accuracy, stability, and ease of use.

Choosing the Right Aftermarket Fence

When choosing an aftermarket fence, consider the following:

• Accuracy: Look for a fence that is known for its accuracy and reliability.
• Ease of Use: Choose a fence that is easy to adjust and lock in place.
• Compatibility: Make sure the fence is compatible with your table saw model.
• Durability: Opt for a fence made from high-quality materials that will last for years.
• Features: Consider features like micro-adjustments and measuring scales.

Popular Aftermarket Fence Brands

Several reputable brands offer high-quality aftermarket table saw fences, including:

• Incra: Known for their precision and micro-adjust capabilities.
• Vega: Offers durable and accurate fences for various table saw sizes.

Table Saw Rip Fence Explained

The table saw rip fence explained simply, is the fence used for making rip cuts. Rip cuts are cuts made along the length of the wood, parallel to the wood grain. The rip fence guides the wood to ensure a straight and consistent cut. It is the primary fence used for most woodworking projects.

Ripping Safely

When ripping wood, use push sticks or push blocks to keep your hands away from the blade. Never reach over the blade to retrieve cut pieces.

Table Saw Fence Setup for Optimal Performance

Proper table saw fence setup is essential for achieving the best results. Here are some key considerations:

1. Squaring the Fence to the Blade

Ensure that the fence is perfectly square to the blade. This means that the fence is at a 90-degree angle to the blade. Use a square or a reliable measuring tool to check this.

2. Setting the Fence Distance

Set the fence distance accurately. Use a measuring tape or a digital caliper to measure the distance from the blade to the fence. Double-check the measurement before locking the fence in place.

3. Securing the Fence

Make sure the fence is securely locked in place. A loose fence can shift during the cut, resulting in inaccurate or dangerous cuts.

4. Test Cuts

Always make test cuts before working on your final project. This allows you to verify the accuracy of your fence setup and make any necessary adjustments.
