Scarf Joint
A scarf joint is a special way of connecting two pieces of wood together to make them look and act like one longer piece. Think of it like a puzzle piece connection that's angled or sloped, which makes the joint stronger than just putting two pieces end-to-end. Carpenters use scarf joints when they need to make something longer than the wood pieces they have, or when they need to repair part of a wooden beam without replacing the whole thing. It's commonly used in timber framing, boat building, and furniture making. Other names for similar techniques include "splice joint" or "scarfed joint."
