A dado plane is a hand tool specifically designed for creating dado joints in woodworking. It is a flat-bodied plane with a broad and square blade that extends the entire width of the plane's body. The blade is set in the middle of the plane, protruding slightly from the sole. The dado plane is primarily used to cut grooves or dados along the grain of a wooden board or panel to accommodate other pieces of wood, such as shelves or dividers.
To use a dado plane, a woodworker would first adjust the blade to the desired depth and width of the dado. The plane is then guided along the workpiece with the blade edge against the wood, removing material gradually to create a smooth and precise groove. The dado plane typically has a handle on top, allowing the user to firmly hold and guide the tool during the cutting process.
Dado planes are widely used in carpentry and cabinetmaking for creating precise and neat dado joints, where the edges of the grooves are clean and parallel. These joints are commonly found in furniture construction, shelving, and cabinetry, serving as strong and stable connections between different components. The dado plane is distinguished from other hand planes by its unique design and specialized function, making it an essential tool for woodworkers seeking accuracy and efficiency in creating dado joints.
The word "dado plane" originates from the combination of two terms: "dado" and "plane".
1. Dado: The term "dado" is derived from the Italian word "dado", which means "dice" or "cube". In woodworking, a dado refers to a slot or trench cut across the grain of a piece of wood. The term likely entered the English language in the late 17th century, primarily through carpentry and joinery practices.
2. Plane: The word "plane" derives from the Latin word "plānum", meaning "level" or "flat". In the context of woodworking, a plane is a hand tool used to shape, smooth, and flatten wood surfaces.
Therefore, the term "dado plane" evolved to describe a specific type of plane used for cutting dadoes or trenches in wood.
