A dado joint is a woodworking joint created by cutting a groove across the grain of a piece of wood. This groove allows another piece of wood, often a shelf or panel, to fit snugly into it, providing strong support and stability. Dado joints are commonly used in cabinetry and furniture making.
To create a dado joint, woodworkers typically use a table saw or a router to make precise cuts. The joint can be reinforced with glue or screws for added strength. Dado joints are favored for their ability to distribute weight evenly, making them ideal for shelving systems.
