What is a Table Saw?
A table saw is a versatile power tool used in woodworking to make straight cuts in various types of materials, such as wood, plastic, and metal. It consists of a circular saw blade mounted on an arbor that is driven by an electric motor. The blade protrudes through the top of a flat table surface, allowing the user to carefully guide the material being cut.
Table saws are commonly used in woodworking shops, construction sites, and home workshops due to their ability to make precise and clean cuts. They are especially useful for ripping boards (cutting them lengthwise) and crosscutting (cutting them widthwise). The depth and angle of the cut can be adjusted, giving the user more control over the final result.
Main Components of a Table Saw
- Tabletop: This is the flat surface of the table saw where the material to be cut is placed and guided. It is usually made of cast iron or aluminum, which provides stability and rigidity.
- Blade: The blade is the most crucial part of the table saw. It is responsible for cutting the material. Blades come in different sizes and types, depending on the desired cut and the type of material being worked on.
- Rip Fence: The rip fence is a guide that runs parallel to the blade and helps keep the material straight during a rip cut. It can be adjusted and locked into position to ensure accurate and repeatable cuts.
- Miter Gauge: The miter gauge is another guide used for making crosscuts at different angles. It is adjustable and can be set to specific angles, allowing the user to make precise angled cuts.
- Motor: The motor provides the power for the saw blade to rotate. It is typically located beneath the tabletop and can be powered by electricity, gasoline, or compressed air.
- Blade Guard: The blade guard is a safety feature that covers the exposed part of the blade. It helps protect the operator from accidental contact with the blade and also prevents debris from being thrown back.
- On/Off Switch: The on/off switch controls the power supply to the motor. It is usually located in a convenient position, allowing the user to quickly start and stop the saw.
Table saws can be used for a variety of tasks, from simple woodworking projects to more complex carpentry jobs. They are a valuable tool in any workshop and with the proper knowledge and skill, can be used safely and effectively to achieve professional results.
What is a Jointer?
A jointer, also known as a planer, is a woodworking tool used to create a flat surface along the length of a board. It is commonly used in woodworking shops to prepare wood for joinery, and to ensure that the wood is straight and free of warping or twisting.
The jointer consists of a flat table with an adjustable fence, and a rotating cutter head with multiple cutting blades. The wood is fed through the machine, and the cutter head removes a small amount of material from the surface of the board, creating a smooth, even surface.
Using a jointer is essential for achieving precise, tight-fitting joints in woodworking projects. It allows for the creation of flat, squared edges, which are necessary for gluing boards together or creating clean, straight cuts.
While a jointer is a dedicated machine for flattening and straightening boards, a table saw can be used as a makeshift jointer by following certain techniques and precautions.

Section 2: How to Use a Table Saw as a Jointer
Using a table saw as a jointer is a great way to save space and money in your workshop. While a jointer is a dedicated tool for flattening and squaring edges, a table saw can be used as a makeshift jointer with a few modifications and techniques. Here’s how you can use a table saw as a jointer:
Step 1: Align the Blade
The first step is to align the table saw blade parallel to the miter slot. You can use a dial indicator or a measuring tape to ensure the blade is perfectly parallel. Adjust the blade tilt and height as needed to achieve the desired alignment.
Step 2: Set the Fence
Next, set the table saw fence to the desired width for your jointing operation. Make sure the fence is aligned parallel to the blade. Use a square to ensure that the fence is perfectly square to the table saw top.
Step 3: Jointing the Edge
Once the blade and fence are properly aligned, you can start jointing the edge of your workpiece. Stand the workpiece on its edge against the fence, with the edge you want to joint facing the blade. Apply gentle pressure and slowly push the workpiece through the blade, keeping it firmly against the fence.
Repeat this process for each edge you want to joint, ensuring that each pass is consistent and results in a flat and square edge. Take your time and use a featherboard or push stick to maintain control and prevent kickback.
Step 4: Finishing Touches
After jointing the edges, you may need to do some additional sanding or planing to achieve a smooth and perfectly flat surface. You can use a hand plane or a belt sander to remove any remaining imperfections and achieve the desired result.
It’s worth noting that using a table saw as a jointer is not a perfect substitute for a dedicated jointer, especially when dealing with longer or wider boards. However, it can be a useful technique for smaller projects or when space and budget constraints make a jointer unattainable.
Remember to always prioritize safety when using power tools, and wear appropriate safety gear such as goggles and ear protection. Happy jointing!
Note: Always follow the manufacturer’s instructions and consult woodworking experts for guidance on specific techniques and safety measures.
Step 1: Adjusting the Fence
The first step in using a table saw as a jointer is to adjust the fence, which is the guide that runs parallel to the blade. The fence is used to keep the board aligned and straight as it passes through the blade. To ensure accurate and precise cuts, you need to adjust the fence properly.
1. Measure the Distance
To begin, measure the width of the board that you want to joint. This measurement will determine the distance between the fence and the blade. Use a measuring tape or a ruler to get an accurate measurement.
2. Align the Fence
Once you have the measurement, position the fence so that it aligns with the measurement you took. Make sure the fence is parallel to the blade and that there is no gap between them. You can use a square or a straight edge to check the alignment. Adjust the fence accordingly until it is perfectly parallel to the blade.
3. Lock the Fence
After adjusting the fence, lock it in place to ensure that it doesn’t move during operation. Most table saws have a locking mechanism that can be tightened to keep the fence secure. Double-check the alignment before locking the fence to ensure its accuracy.
By adjusting the fence properly, you can ensure that the board will pass through the blade accurately and that you will achieve straight and smooth cuts. Remember to always double-check the alignment before using the table saw as a jointer.
