How Joinery Of Boards Are Done

In woodworking, a biscuit joint uses an oval-shaped biscuit to reinforce and align two boards being joined together. A biscuit joiner (also known as a plate joiner) cuts matching crescent-shaped slots in the mating edges of the wood. When wood glue is applied, the compressed wooden biscuit swells and locks the joint in place, creating a strong and seamless joint that is ideal for cabinet and furniture construction.
