How To Use A Circular Saw As A Table Saw: Step-by-Step

Can I use a circular saw as a table saw? Yes, you can use a circular saw like a table saw by building or buying a jig or mount that secures the saw and allows you to push the material through it. While not a perfect replacement, it can be a cost-effective and space-saving solution for DIYers.

Many people starting woodworking projects might not have a dedicated table saw, but they may have a circular saw. A circular saw is a handheld tool that can cut wood. A table saw is a stationary tool with a flat surface and a blade that sticks up. Turning your circular saw into a table saw can expand your woodworking skills without spending a lot. This article will guide you through building a circular saw table saw jig and using it safely.

Why Consider a Circular Saw Table Saw Alternative?

Before diving into the how-to, it’s good to know why someone would choose this route.

• Cost-Effective: Table saws can be expensive. Using a circular saw as a table saw keeps costs down.
• Space-Saving: Table saws take up a lot of room. A circular saw table saw conversion is good for small workshops.
• Versatile: A circular saw can be used as both a handheld saw and a makeshift table saw.

However, keep in mind that a circular saw used as a table saw has limitations. It may not be as accurate or powerful as a real table saw. Always put safety first.

Planning Your Circular Saw Table Saw Build

First, think about your needs and how often you will be using the circular saw as a table saw. This will help you decide on the type of jig you want to build.

Choosing the Right Circular Saw

Not all circular saws are created equal. Pick a saw with these features:

• Power: A motor with enough power to cut through the materials you plan to use.
• Blade Size: A standard blade size for easy replacement.
• Base Plate: A flat, stable base plate that can be easily attached to a jig.
• Safety Features: A blade guard and a switch that’s easy to reach.

Designing Your Circular Saw Table Saw Jig

Your jig design will depend on your needs and woodworking skills. Here are a few common designs:

• Simple Platform Jig: A basic platform with the saw mounted underneath. Good for small projects.
• Enclosed Table Jig: A more complex jig with a fence and enclosed base. Offers better safety and accuracy.
• Hybrid Jig: A mix of the two, balancing simplicity and features.

Consider these factors when designing your jig:

• Size: Make sure the jig is big enough to support the materials you’ll be cutting.
• Fence: A good fence is important for accurate cuts.
• Safety: Include safety features like blade guards and a kill switch.
• Dust Collection: Think about how you will manage sawdust.

Step-by-Step Guide to Building a Circular Saw Table Saw Jig

This guide will focus on building a simple platform jig, which is a good starting point for most DIYers.

Materials You’ll Need

• Plywood (3/4 inch thick)
• 2×4 lumber
• Screws (various sizes)
• Bolts, nuts, and washers (for mounting the saw)
• Wood glue
• Circular saw
• Drill
• Screwdriver
• Measuring tape
• Square
• Safety glasses
• Hearing protection

Step 1: Cutting the Base

1. Cut a piece of plywood to the size you want for your table. A good starting size is 24×36 inches.
2. Cut 2×4 lumber to create a frame around the edge of the plywood. This will add support and make it easier to attach the fence.
3. Attach the 2×4 frame to the plywood using wood glue and screws. Make sure the frame is square.

Step 2: Mounting the Circular Saw

1. Carefully measure the base plate of your circular saw.
2. Mark the location of the saw blade on the plywood.
3. Cut an opening in the plywood for the saw blade to pass through. Use a jigsaw or a circular saw for this step.
4. Position the circular saw under the plywood, aligning the blade with the opening.
5. Mark the location of the mounting holes on the saw’s base plate.
6. Drill pilot holes through the plywood at the marked locations.
7. Attach the circular saw to the plywood using bolts, nuts, and washers. Make sure the saw is securely mounted.

Step 3: Building the Fence

A fence is needed for straight and accurate cuts.

1. Cut a piece of plywood to use as the fence. A good size is 4 inches high and the length of the table.
2. Attach the fence to the table using clamps or screws. Make sure the fence is square to the blade.
3. For a more adjustable fence, you can use t-tracks and knobs. This allows you to easily move and lock the fence in place.

Step 4: Adding Safety Features

Safety is very important.

1. Build a blade guard to cover the exposed blade. You can use clear plastic or wood for this.
2. Add a push stick to help guide the material through the saw. This keeps your hands away from the blade.
3. Consider adding a kill switch that’s easy to reach in case of an emergency.

Using Your Circular Saw Table Saw

Now that you’ve built your jig, it’s time to use it.

Preparing to Cut

1. Always wear safety glasses and hearing protection.
2. Make sure the blade is sharp and in good condition.
3. Adjust the fence to the desired width of cut.
4. Test the setup with a scrap piece of wood.

Cutting Techniques

1. Turn on the circular saw.
2. Hold the material firmly against the fence.
3. Slowly push the material through the blade, using a push stick to keep your hands safe.
4. Maintain a steady speed and avoid stopping or changing direction mid-cut.
5. Turn off the saw after each cut and wait for the blade to stop before removing the material.

Tips for Accurate Cuts

• Use a Sharp Blade: A dull blade can cause the wood to bind and kickback.
• Keep the Fence Square: Make sure the fence is always square to the blade.
• Apply Even Pressure: Avoid pushing too hard or too soft.
• Use a Push Stick: This helps keep your hands away from the blade.

Circular Saw Fence for Table Saw Use: Different Types

A good fence is the key to accurate cuts. Here are some common types of fences:

• Simple Fence: A straight piece of wood clamped to the table. Good for basic cuts.
• Adjustable Fence: A fence that can be moved and locked in place. Offers more accuracy.
• T-Track Fence: Uses t-tracks and knobs for easy adjustment and secure locking.
• Micro-Adjust Fence: Allows for very fine adjustments, good for precise cuts.

Building an Adjustable Fence

Here’s how to build a simple adjustable fence:

1. Cut a piece of plywood for the fence.
2. Attach two pieces of wood to the underside of the fence, forming a channel that slides along the table.
3. Attach knobs or clamps to lock the fence in place.

Circular Saw Table Saw Safety: A Must-Read

Safety is the most important part of using a circular saw as a table saw. Always follow these safety rules:

• Wear Safety Glasses and Hearing Protection: Protect your eyes and ears from debris and noise.
• Use a Blade Guard: Cover the exposed blade to prevent accidental contact.
• Use a Push Stick: Keep your hands away from the blade when cutting small pieces.
• Never Reach Over the Blade: Avoid reaching over the blade while the saw is running.
• Keep Your Work Area Clean: Remove sawdust and debris to prevent slips and falls.
• Disconnect the Power: Always disconnect the power before making adjustments or changing the blade.
• Be Aware of Kickback: Kickback is when the wood is thrown back towards you. Avoid this by using a sharp blade and feeding the material slowly.
• Never Force the Saw: If the saw is binding, stop and figure out what’s causing the problem.
• Stay Focused: Avoid distractions when using the saw.
• Know Your Limits: If you’re not comfortable with a particular cut, don’t do it.
