Wood : Joining Methods
Traditional wood joints : Wood joints that require machining to make interlocking parts and often combined with adhesive Different types of wood joining methods Dowel Joint Through dovetail Mortise and Tenon Joint Lapped Dovetail All of these joints would be secured with an adhesive such as PVA (Poly Vinyl Acetate), making them permanent.
Dowel Joints What is a dowel joint? A dowel joint is a butt joint reinforced with wooden pegs. A well-made dowel joint is as strong as a mortise and tenon joint. It is often used instead of the mortise and tenon joint if cost is a consideration in the assembly of the work. Dowel holes must be a perfect 90 degrees to the face of the work or the dowel will twist when it is assembled. What are the advantages of this type of joint? Neat strong joint, providing you use strong glue Simple, quick and easy to make What are the disadvantages of this type of joint? Drilling accurate holes can be difficult
Dovetail Joints Through Lapped What is a Dovetail joint? Dovetails are the strongest of all joints. The joint is made up of interlocking wedge-shaped elements called pins and tails that resist the forces applied to the joint. . Dovetail joints work best when in tension. For example, the most common application of the dovetail joint is in drawer making as the strength of the joints tails and pins resist the pulling forces applied to the drawer. What are the advantages of this type of joint? Strongest of all joints. Large gluing area. Interlocking Resists being pulled apart. Looks attractive. Would hold together even with no glue. What are the disadvantages of this type of joint? Can be fairly difficult to mark out and cut. If badly made this joint looses the advantages listed above
Mortise and Tenon Joints What is a Mortise and tenon joint? The mortise and tenon is one of the most common joints used by woodworkers and is the traditional corner joint for sturdy frames. What are the advantages of this type of joint? Neat and very strong. Large surface area for gluing. It cannot wobble. Is difficult to pull out. Most of the joint is hidden in the timber. What are the disadvantages of this type of joint? Can be fairly difficult to mark out and cut. Poor resistance to tension, especially if badly fitted
