Dado
Definition: A dado is a type of groove or channel cut into the surface of a piece of wood, typically in the interior of a cabinet or shelving unit. The dado allows another piece of wood, such as a shelf or divider, to fit securely into the groove, creating a strong joint that improves the cabinet’s stability and strength.
Overview:
In cabinetry and woodworking, a dado is an essential joinery technique used to create a strong and precise connection between two pieces of wood. Dadoes are commonly used in shelving systems, drawer construction, and cabinet backs to provide a secure fit for shelves or dividers. The groove is typically cut across the grain of the wood to hold a shelf or divider in place, helping to distribute weight evenly and reduce the risk of sagging or damage.
Key Features:
- Groove Dimensions: A dado is typically a wide, flat-bottomed groove, which can vary in depth and width depending on the needs of the project. The shelf or divider is placed into the dado groove, fitting snugly for a secure hold.
- Types of Dadoes:
- Through Dado: The groove cuts all the way through the wood, leaving visible cuts on both sides.
- Blind Dado: The groove is cut into the wood but does not go all the way through, leaving no visible cuts on the exterior of the piece.
- Housing Dado: A variant where the groove is cut on both sides of the wood, creating a more robust joint for shelves or dividers.
- Application: Dadoes are often used in cabinet construction for shelving, dividers, or backs, where precise alignment and strength are needed. The groove helps hold the shelf or other components in place, offering added support and longevity.
Why Use a Dado in Cabinetry?
Dado joints are a popular choice in cabinetry because they provide a strong and secure method for joining two pieces of wood. When used correctly, a dado joint can significantly increase the strength of a cabinet or shelf, preventing sagging and ensuring that shelves remain firmly in place. The precision of a dado also ensures that your shelving units and cabinets are well-aligned, which is crucial for both aesthetics and functionality.
