Planning Your Table Saw Fence

Before you start cutting wood, you need a solid plan. Here’s what to consider:

Assess Your Needs

• What kind of projects do you typically work on? Do you need a fence that can handle large sheet goods, or are you mainly working with smaller pieces?
• What level of accuracy do you require? Are you building fine furniture that demands precision, or rougher projects where a little variation is acceptable?
• What is your budget? Fence materials can range from inexpensive plywood to costly steel.
• What are your existing table saw’s dimensions? You’ll need to know the size of your table saw top and the distance between the miter slots.

Choosing a Design

There are several table saw fence plans to choose from, each with its own advantages and disadvantages. Here are a few popular options:

• Simple Wooden Fence: This is the easiest and cheapest option. It consists of a wooden fence attached to a simple locking mechanism. While it is easy to make, this will likely be the least accurate.
• T-Square Fence: This design uses a T-shaped frame that slides along a rail. It’s more stable and accurate than a simple wooden fence. This is a very popular design for build accurate table saw fence.
• Micro-Adjustable Fence: This type of fence incorporates a mechanism that allows for fine-tuning the fence position. Ideal for tasks requiring extreme precision.
• Hybrid Fence: Combines elements of the above designs for a balance of accuracy, stability, and cost.

Materials Selection

The materials you choose will significantly impact the performance and longevity of your fence.

• Fence Body:
  • Hardwood: Maple, oak, or cherry offer excellent stability and durability, but they can be more expensive.
  • Plywood: High-quality Baltic birch plywood is a good alternative, providing stability at a lower cost. Avoid cheaper grades of plywood that may warp.
  • MDF (Medium-Density Fiberboard): MDF is flat and stable, but it’s also heavy and can be damaged by moisture.
• Rails:
  • Steel: Steel rails provide the most rigidity and accuracy. You can purchase pre-made steel rails or fabricate your own.
  • Aluminum: Aluminum is lighter than steel but still provides good stability.
  • Hardwood: Hardwood rails can be used, but they may not be as rigid as metal rails.
• Hardware:
  • Bolts and Screws: Use high-quality hardware to ensure a secure and lasting connection.
  • Locking Mechanism: A robust locking mechanism is crucial for maintaining fence position. Options include cam clamps, toggle clamps, or threaded knobs.
  • T-Track: Useful for attaching jigs and accessories to your fence.

Building Your T-Square Table Saw Fence: A Step-by-Step Guide

This guide focuses on building a T-square fence, striking a balance between accuracy, cost, and ease of construction. Feel free to adapt these instructions based on your chosen design and materials.

Step 1: Prepare the Rails

1. Cut the Rails: Cut your front and back rails to the desired length. The length should be slightly longer than your table saw’s width to allow for full travel of the fence. Ensure the cuts are square.
2. Mill the Rails (If Necessary): If using hardwood, mill the rails to ensure they are flat, straight, and square.
3. Attach Mounting Hardware: Drill and countersink holes for attaching the rails to your table saw. The exact placement will depend on your saw’s design. Consider using T-nuts or threaded inserts for a more secure connection.

Step 2: Build the Fence Body

1. Cut the Fence Body Components: Cut the main fence body, face, and any reinforcing pieces from your chosen material. Aim for a tall fence (3-4 inches) to provide ample support for the workpiece.
2. Assemble the Fence Body: Glue and screw the components together, ensuring everything is square and aligned. Use clamps to hold the pieces in place while the glue dries.
3. Add a Replaceable Face (Optional): Consider attaching a replaceable wooden face to the fence. This allows you to easily replace it if it becomes damaged or worn. Use countersunk screws for easy removal and replacement.
4. Install T-Track (Optional): If desired, rout a groove for and install T-track along the fence face. This allows you to attach feather boards, stops, and other accessories.

Step 3: Construct the T-Square Frame

1. Cut the T-Square Components: Cut the T-square frame pieces from your chosen material. The width of the T-square should match the distance between your table saw’s rails.
2. Assemble the T-Square Frame: Glue and screw the components together, ensuring the frame is square and rigid. Use metal brackets or reinforcing blocks for added strength.
3. Attach the Fence Body to the T-Square Frame: Carefully align the fence body with the T-square frame and attach it securely using screws and glue. Ensure the fence is perfectly perpendicular to the T-square.

Step 4: Install the Locking Mechanism

1. Choose a Locking Mechanism: Select a locking mechanism that suits your needs and budget. Options include cam clamps, toggle clamps, or threaded knobs.
2. Install the Locking Mechanism: Install the locking mechanism on the T-square frame, ensuring it securely clamps the fence to the rails. Follow the manufacturer’s instructions for installation.
3. Test the Locking Mechanism: Test the locking mechanism to ensure it holds the fence firmly in place without any slippage.

Step 5: Fine-Tune and Adjust

1. Install the Fence on Your Table Saw: Attach the rails to your table saw using the mounting hardware you prepared earlier.
2. Align the Fence: Use a precision square or a reliable measuring tool to align the fence parallel to the saw blade. Make small adjustments to the rail position until the fence is perfectly aligned.
3. Test Cuts: Make several test cuts to verify the accuracy of the fence. If necessary, make further adjustments to the fence alignment or locking mechanism.
4. Add Scale (Optional): Add a measuring tape or adhesive scale to the fence rails for easy and repeatable cuts.

Step 6: Final Touches

1. Sand and Finish: Sand all surfaces of the fence smooth and apply a durable finish, such as polyurethane or lacquer.
2. Add Accessories: Attach any desired accessories, such as feather boards, stops, or hold-downs.

Tips for Achieving a Precise Table Saw Fence

• Start with Accurate Measurements: Precision begins with accurate measurements. Double-check all dimensions before cutting any wood.
