For a beginner, one of the most daunting aspects of building a piece of furniture is deciding what joints to use.
If you were building a cabinet or sideboard with a face frame that intersects at various points, you might use a half-lap joint.
Tongue-and-groove joints provide a mechanical means of registering and joining the edges of narrow boards when forming a wider panel.
The finger joint, sometimes called a box joint, interlocks two boards at a corner similar to a dovetail. Considered one of the strongest and certainly the most beautiful of joints, the dovetail exacts a stiff price in terms of skill for the strength and good looks it provides. This joint consists of a dovetail-shaped tenon that slides into a corresponding groove or plow. Show off the joint if it's appropriate--Nothing looks better than eye-popping dovetails or a tight, pinned mortise-and-tenon. Choosing the wrong joint can complicate construction, conflict with the design, undermine its integrity, and maybe even cause premature failure of a piece. Put simply, a dado is cut across the grain of one board to receive the end of another board.


On this joint you remove the full width of each intersecting member but only half of the thickness. This joint can be used to join the rails and stiles on frame-and-panel doors, the aprons to the legs of tables, and the rails to the posts or legs of chairs.
It can be used like a dado for supporting shelves on a bookcase while offering extra strength to keep the sides of the bookcase from bowing outward. The joint must allow for additional operations, such as grooving, rabbeting, moldings, or screws. A good place to begin when faced with the task of choosing a joint for a certain application is to identify and study the most widely used joints; there literally are hundreds of them in various configurations. The strength of this joint relies on the straightness of the edges (not necessarily the squareness). Several half-lap joints on a cabinet face frame will ensure that it is rigid and long-lasting. This joint has a clean, utilitarian look that makes it perfect for kitchen, office, or shop containers. The first hurdle is to cut each half of the joint to 45 degrees; then you have to figure out a way to glue them together without one half slipping past the other.


Crowding the joint with pins can leave too little material on the tail board to support the joint.
Then consider the joints traditionally used in a particular type of furniture and evaluate your ability to execute them. Half-blind dovetails are most commonly used to join drawer sides to drawer fronts, but occasionally you'll find the joint employed in the construction of carcases.
Disadvantages are that the joint is visible from the end of the panel and the joint requires precise milling to ensure that all parts fit correctly. In this article I highlight some of the most standard joints and their common applications.
