What is a lap joint?
A lap joint is a type of wood joint in which two pieces of wood overlap each other to create a strong and secure connection. It is commonly used in woodworking projects to join two pieces of wood together, such as in building furniture or constructing frames.
The lap joint is created by cutting a recess or notch in one piece of wood, called the “shoulder,” and a corresponding notch in the other piece of wood, called the “tenon.” When the two pieces of wood are fitted together, the recess and notch interlock, creating a flush surface.
This type of joint is known for its strength and stability, as the overlapping sections provide a large glue surface and increased contact area between the two pieces of wood. It is relatively easy to create a lap joint with a circular saw, making it a popular choice for DIY enthusiasts and woodworking beginners.
Lap joints are commonly used in applications where strength and stability are important, such as in constructing beams, framing walls, or building sturdy furniture. They can be used with a variety of different wood types and thicknesses, making them versatile and adaptable to different projects.
In summary, a lap joint is a type of wood joint that involves overlapping two pieces of wood to create a strong and secure connection. It is commonly used in woodworking projects and provides strength, stability, and versatility to a variety of applications.
