Description
A finger joint, also known as a comb joint, is a woodworking joint made by cutting a set of complementary, interlocking profiles in two pieces of wood, which are then glued. The cross-section of the joint resembles the interlocking of fingers between two hands, hence the name “finger joint”. The sides of each profile increases the surface area for gluing, resulting in a strong bond, stronger than a butt joint but not very visually appealing. Thus, it is commonly used for joinery and carpentry works that are concealed.
USES
A tapered or scarfed finger joint is the most common joint used to form long pieces of lumber from solid boards; the result is finger-jointed lumber. The finger joint can also be valuable when creating baseboards, moulding or trim, and can be used in such things as floor boards, and door construction.
