Difference between Jointer and Planer
When it comes to woodworking, both jointers and planers are essential tools for achieving smooth, flat surfaces on wood. However, many woodworkers often confuse these two tools, as they serve similar purposes. This article aims to highlight the key differences between a jointer and a planer, helping you understand when and how to use each one effectively.
Function and Purpose
The primary function of a jointer is to joint the edges of boards, ensuring they are straight and parallel. This is particularly useful when you have boards with uneven or bowed edges that need to be corrected. On the other hand, a planer is designed to reduce the thickness of wood, producing a smooth, flat surface. It is ideal for making boards uniform in thickness, which is essential for achieving precise cuts and joints.
Design and Features
Jointers typically have a larger footprint and a wider infeed table, which allows for wider boards to be jointed. They come with adjustable infeed and outfeed tables to accommodate boards of different widths. Planers, on the other hand, are usually more compact and have a smaller footprint, making them suitable for smaller workshops or limited spaces. Planers also feature a cutter head with rotating blades that remove wood as the board passes through.
Blade Design
The blade design is another significant difference between jointers and planers. Jointers usually have a single blade, which is typically 1/4 inch thick. This single blade ensures that the wood is jointed evenly, preventing the board from being cupped or bowed. Planers, on the other hand, have multiple blades arranged in a set, usually with a thickness of 1/8 inch. This design allows for faster and more efficient wood thickness reduction.
Speed and Feed Rate
Jointers typically operate at a slower speed, which is essential for jointing the edges of boards without causing damage. The feed rate for a jointer is usually around 6 to 8 feet per minute. Planers, on the other hand, are designed to work at higher speeds, with feed rates ranging from 8 to 12 feet per minute. This faster speed makes planers more efficient when it comes to reducing wood thickness.
Conclusion
In conclusion, the main difference between a jointer and a planer lies in their functions and features. While a jointer is designed to joint the edges of boards, a planer is used to reduce the thickness of wood. Understanding these differences will help you choose the right tool for your woodworking needs, ensuring that your projects turn out smooth, flat, and precise.
