1" x 2" x 12" Finger Joint Timber
Finger joints are generally created by using identical profiles for both pieces. They are made complementary by rotation or translation of the tool with respect to the workpiece. Typically a finger router bit is used, but spindle molders can also be used. Manual cutting of finger joints is time-consuming and error-prone hence rarely done except in craft pieces.
-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, molding or trim, and can be used in such things as floorboards, and door construction.
