A self-centering and self-aligning joint is presented for bonding a first and second wood segment, wherein the joint includes a single tenon extending from the end face of the first segment, and a void disposed within the end face of the second segment. And adhesive is applied to the outer surface of the tenon, or to the inner surface of the void to join the two segments.

Joint for connecting wood members

A finger joint for connecting first and second wooden segments includes intermeshing fingers that are concentrically disposed about the center of the end face of the two wooden segments. The fingers may either be independent round protrusions forming recesses therebetween operable to receive the fingers of a corresponding wooden segment to be joined, or may alternatively comprise a spiral shaped protrusion defining a corresponding recess sized to receive the spiral shaped protrusion of the corresponding wooden segment to be joined.
