Difference between Table Saws and Jointers
Two common machines that often get confused are table saws and jointers. While both tools, such as the board and sled, are used in woodworking projects, they serve different purposes and have distinct features. Let’s explore the key differences between table saws and jointers.
Primary Functions
Table saws are primarily used for cutting wood pieces into desired shapes and sizes. They consist of a circular blade mounted on an arbor that protrudes through the surface of a flat table. Woodworkers can adjust the height and angle of the blade to make precise cuts, such as rip cuts or crosscuts. The board and sled are essential tools for guiding the wood through the saw, ensuring accurate and safe cuts.
On the other hand, jointers with rotating knives positioned just above its surface are specifically designed for flattening wood surfaces, creating straight edges, and ensuring boards are perfectly square. A jointer has a long bed where you can run a piece of wood over to shave off any unevenness or imperfections, leaving behind a smooth and flat surface. This tool is essential for woodworking projects involving sleds.
Cutting Mechanisms
Table saws utilize circular blades that spin at high speeds to cut through wood fibers. The teeth on these blades remove material as they pass through the workpiece, resulting in clean cuts across various types of wood. These cuts are particularly useful when working with a board or sled.
Jointers employ cutterheads equipped with multiple sharp blades or knives positioned close together in a cylindrical formation. These blades, known as sled, rotate rapidly while cutting across the width of a board on the jointer’s bed. By removing thin layers of material with each pass, jointers create flat surfaces by leveling out any irregularities present in the wood.
Unique Features
Table saws commonly feature adjustable fences that help guide wood boards during cutting operations, ensuring accuracy and consistency in each cut. They also offer options for making bevel cuts at different angles by tilting the blade.
In contrast, jointers have an adjustable fence parallel to their cutterhead which helps maintain consistent edge alignment when flattening boards. Jointers often include a built-in mechanism called a “guard,” which protects the user from the rotating cutterhead and prevents accidents.
Both table saws and jointers have their unique benefits and are suitable for specific tasks. Table saws excel at cutting large pieces of wood into various shapes, while jointers are indispensable for board preparation.
Pros and Cons of Using a Table Saw for Jointing
