The junction of two pieces of wood or veneer.
  • Butt Joint - An end joint formed by abutting the squared ends of two pieces. Because of the inadequacy in strength of butt joints when glued, they are not generally used.
  • Edge Joint - The place where two pieces of wood are joined together edge to edge, commonly by gluing. The joints may be made by gluing two squared edges as in a plain edge joint or by using machined joints of various kinds, such as tongue-and-grooved joints.
  • Scarf Joint - An end joint formed by joining with glue and mechanical fastenings the ends of two pieces that have been tapered or beveled to form a sloping plane surface, to the same length in both pieces. In some cases, a step or hook may be machined into the scarf to facilitate alignment of the two ends, in which case, the plane is discontinuous and the joint is known as a stepped or hooked scarf joint or scarf joint with nib.
  • End Joint - The place where two pieces of wood are joined together end to end, commonly by scarfing and gluing.
  • Lap Joint - A joint made by placing one piece partly over another and bonding the overlapped portions.
  • Starved Joint - A glued joint that is poorly bonded because insufficient quantity of glue remained in the joint. Starved joints are caused by the use of excessive pressure or insufficient viscosity of the glue, or a combination of these, which result in the glue being forced out from between the surfaces to be joined. This term should only apply to epoxy glues. Joints made with other waterproof or water resistant glues like resorcinol and urea-formaldehyde (brown glue) should be starved for maximum strength.

A term common to wooden boat design and construction.
