Mortise

Definition

The hole which is to receive a tenon, or any hole cut into or through a piece by a chisel; generally of rectangular shape.

Purpose

Mortises are used in joinery and woodworking to create strong, interlocking connections between pieces of wood. The mortise receives the tenon, forming a tight, secure joint that enhances the structural integrity and stability of the assembled pieces.

Examples of Use

• Furniture making: Creating mortises in wooden pieces to join legs, frames, and other components.
• Door frames: Cutting mortises to fit door hinges securely.
• Timber framing: Using mortises in timber beams and posts to construct traditional wooden structures.

Related Terms

• Tenon: A tongue-like protrusion on the end of a piece of wood that fits into a mortise.
• Mortise-and-Tenon Joint: A joint formed by fitting a tenon into a mortise, commonly used in woodworking and joinery.
• Chisel: A hand tool used to cut or shape wood, stone, or metal.

Notes

• Mortises can be created using hand tools, such as chisels and mallets, or power tools, such as mortising machines and routers.
• The dimensions and fit of the mortise and tenon must be precise to ensure a strong, stable joint.
• Mortise-and-tenon joints are prized for their strength and durability, often used in high-quality woodworking and furniture making.
