Why Are Planers Called Jointers
Planers and jointers are two popular woodworking tools that are often mentioned in the same breath. While they have slightly different functions, both are essential for achieving smooth and flat surfaces in woodworking projects.
A jointer is a machine that is primarily used to flatten and square the edges of boards. It features a long, flat bed with an adjustable fence, and a set of rotating blades or knives that remove material from the wood as it is passed over the bed. This process ensures that the edges of the board are perfectly straight and perpendicular to the face, making it easier to join them together to create larger panels or tabletops.
So why are planers called jointers? The term “jointer” comes from the fact that this machine is used to create a perfect joint or seam between two pieces of wood. By flattening the edges of the boards, a jointer helps ensure that they fit together seamlessly, without any gaps or irregularities. This is crucial for creating strong and stable connections in woodworking projects, such as when building cabinets, furniture, or doors.
The Origins of Planers
The history of planers can be traced back to ancient times, where they were primarily used in woodworking. The earliest known planers were simple hand tools consisting of a sharpened blade attached to a wooden block. These early planers were used to smooth and shape wood surfaces by removing thin layers of material.
Over time, planers evolved and became more advanced. In the 18th century, the invention of the jointer planer revolutionized the woodworking industry. Jointer planers allowed for the simultaneous planing and squaring of rough lumber, making them a versatile and efficient tool.
The term “jointer” is derived from the tool’s original purpose – to create a flat, jointed surface on a piece of wood. By running the wood through the jointer, craftsmen were able to create a smooth and even surface, which was essential for creating flat and well-fitting joints. The name “jointer” eventually became synonymous with planer, as the two terms came to represent similar tools used for similar purposes.
Today, planers are widely used in woodworking and are available in various sizes and configurations. They are used to create smooth and flat surfaces on boards, remove imperfections, and resize lumber to the desired thickness. Electric planers have also become popular, offering increased speed and precision compared to their manual counterparts.
Overall, the origins of planers can be traced back to the need for woodworking tools that could efficiently shape and smooth wood surfaces. Through centuries of innovation and technological advancements, planers have become an essential tool in the woodworking industry, enabling craftsmen to create high-quality and precise woodwork.
Discovering the History
Understanding the history behind why planers are called jointers is essential to appreciating their unique function and value. The term “jointer” originated from the woodworking technique known as “jointing,” which involves making the edges of boards flat and straight.
Early jointing methods relied on hand tools, such as hand planes, or simple wooden contrivances designed to achieve a straight and true edge. These tools, while effective, required a significant amount of skill and effort to produce consistent results.
In the late 19th century, the introduction of machine-powered jointing revolutionized the woodworking industry. This new machine, later known as a jointer, made the process of jointing more efficient and accurate.
The jointer, as it is known today, consists of a flat table and a rotating blade assembly. The user feeds the board through the machine, and the blade shaves off small increments of material, creating a flat and even surface. This method is commonly used to flatten one face or edge of a board before it is further processed.
Over time, the term “jointer” became synonymous with this specific machine, despite the fact that it also performs other functions beyond jointing. Today, jointers are used not only for creating flat edges but also for tapering, chamfering, and other related tasks.
Understanding the history and evolution of jointing and the jointer itself helps one appreciate the significance of this versatile woodworking tool. Whether it is called a jointer or a planer, its purpose remains the same: to create flat and straight surfaces with precision and efficiency.
Understanding Jointers
A jointer is a woodworking machine/tool that is used to create a flat surface on a piece of lumber. It is an essential tool for ensuring that the edges of boards are straight and square, which is crucial for creating strong and accurate joinery.
Jointers are typically made up of a flat table that is used as a reference surface, and a rotating cutter head. The cutter head contains multiple cutting blades that remove material as the wood is passed over it. The depth of the cut can be adjusted based on the desired thickness of the board.
Using a jointer involves feeding the wood across the table, with one face pressed firmly against the table. The wood is guided by a fence, which keeps the edge of the board straight and perpendicular to the table. As the wood is fed through the jointer, the cutter head shaves off small amounts of material, effectively planing the surface and creating a smooth and flat edge.
By using a jointer, woodworkers can ensure that their boards have straight and square edges, which is essential for creating strong and precise joinery. This is especially important when working with multiple boards that need to be joined together, such as when creating tabletops or cabinet doors.
While jointers are primarily used for edge jointing, they can also be used for face jointing. Face jointing involves passing a board through the jointer with its face pressed against the table, ensuring that the surface is flat and smooth.
- Jointers are available in various sizes, with larger jointers being able to handle wider and longer boards.
- It is important to properly set up and maintain a jointer to ensure accurate and safe operation.
- When using a jointer, it is advisable to wear safety equipment, such as safety glasses and hearing protection, as the machine can produce loud noises and flying debris.
In conclusion, jointers are essential tools for ensuring straight and square edges on boards, allowing woodworkers to create strong and accurate joinery. By using a jointer, woodworkers can achieve professional results and improve the quality of their woodworking projects.
Exploring Their Function
Planers and jointers are both essential tools in woodworking, but they serve different purposes.
A jointer, also known as a planer or edge jointer, is primarily used to ensure that two adjoining pieces of wood have a perfectly flat and straight edge. This is crucial for joinery work, where pieces need to be accurately matched together. The jointer accomplishes this by running the edge of a board along a cutterhead, which shaves off any high spots or irregularities.
On the other hand, a planer, also known as a thickness planer or surface planer, is used to create a uniform thickness on a piece of wood. This is especially useful when working with rough lumber that has uneven surfaces. The planer achieves this by passing the wood through a set of rotating blades, which remove material from the surface until it reaches the desired thickness.
Jointer Function:
- Creates flat and straight edges on boards
- Eliminates high spots and irregularities
- Prepares boards for joinery work
Planer Function:
- Creates a uniform thickness on boards
- Removes material from uneven surfaces
- Ideal for working with rough lumber
In summary, jointers and planers are essential tools in woodworking that serve different functions. While jointers are used to create flat and straight edges on boards for joinery work, planers are used to create a uniform thickness on boards and remove material from uneven surfaces.
Planers vs. Jointers
Both planers and jointers are essential tools in woodworking, but they have different functions and purposes. Understanding the differences between these two machines can help you achieve the best results in your woodworking projects.
Planers
A planer, also known as a thickness planer, is primarily used to flatten and smooth rough lumber. It has a flat cutting platform and a rotating cutterhead with multiple blades. The wood is fed into the planer, and the blades remove thin layers from the surface, creating a smooth and uniform thickness across the entire piece of wood. This makes planers ideal for preparing lumber for furniture making and other applications where a smooth and even surface is required.
Planers are available in different sizes, ranging from portable benchtop models to larger industrial-grade machines. They are typically used after the jointing process when one side of the wood is already flattened and straight, allowing for consistent thickness throughout the piece.
Jointers
A jointer, also known as a surface planer, is used to flatten and straighten the edges of rough lumber. It consists of a flat table and a rotating cutterhead with a set of knives. The wood is fed into the jointer with the rough edge against the fence, and the knives remove thin layers from the wood, creating a straight and square edge.
Jointers are essential for ensuring that the edges of boards are perfectly flat and square before joining them together. This is particularly important when creating panels, tabletops, and other flat surfaces where seamless joints are desired. By using a jointer, woodworkers can create precise and tight-fitting joints, resulting in professional-quality woodworking projects.

A planer, on the other hand, is primarily used for making a piece of wood a consistent thickness throughout its length. It works by feeding the wood through a set of rotating blades, which remove material from the top surface until the desired thickness is achieved.
Planers are commonly used to dimension lumber and create boards of a uniform thickness. They are ideal for creating blanks for furniture making or for preparing stock for further shaping or joinery.
While both jointers and planers are critical tools in woodworking, they serve different purposes. A jointer is used to flatten and straighten wood, while a planer is used to create uniform thickness. Together, these tools can help transform rough lumber into smooth, flat, and consistently thick boards ready for use in various woodworking projects.
It’s important to note that both jointers and planers require proper setup and technique to ensure safe and accurate operation. Always follow the manufacturer’s instructions and take proper safety precautions when using these tools.
Jointing and Planing Techniques
Jointing and planing are essential techniques in woodworking that help to create smooth and flat surfaces on wood. These techniques are commonly used in furniture making, cabinetry, and other woodworking projects.
Jointing
Jointing is the process of creating a straight and flat edge on a piece of wood. This is typically done using a jointer, which is a woodworking machine that utilizes rotating knives to remove material from the wood surface.
To joint a piece of wood, it is first necessary to determine which edge needs to be jointed. The selected edge is then placed against the jointer’s fence, which helps to guide the wood as it passes through the machine. As the wood is fed through the jointer, the rotating knives remove any uneven or protruding areas to create a straight and flat edge.
Planing
Planing, on the other hand, involves creating a smooth and flat surface on a piece of wood. This is typically done using a planer, which is a machine that compresses the wood against a flat surface while rotating blades remove material from the opposite side.
To plane a piece of wood, it is first necessary to determine which side needs to be planed. The wood is then fed through the planer, and the rotating blades remove any uneven or high spots, resulting in a smooth and flat surface.
Both jointing and planing techniques are important in woodworking, as they allow for precise and accurate dimensioning of wood. These techniques help to ensure that surfaces are flat and smooth, making it easier to join pieces together and create high-quality finished products.
