A structural joint for attaching two boards by their butts, achieving the correct transmission of forces between them by means of a staggered configuration of the butts thereof to increase the contact surface between both boards, allowing the mutual coupling thereof, both being aligned and coplanar, and at least one of the steps of both boards having a finger profile to further increase the contact surface between both boards.

The present invention discloses a compound lumber product, relating to the technical field of wooden materials for making furniture, and particularly to a compound lumber product that may be used for making furniture. The compound lumber product includes a core lumber and side-members surrounding the core lumber. The core lumber may be one piece or formed from several core members. The side-members may be single-piece or formed by joining together several high-grade wood boards or strips. Side-members are arranged side by side around the outer surface of the core lumber, wrapping around the core lumber with tail edge of a preceding side-member secured or connected to the inner side-face of the subsequent adjoining side-member at its head edge in a head-to-tail manner, to form the enclosure structure.

A router jig includes a router jig base having: (i) a first board guide that receives an end of a first board; (ii) a second board guide that receives an end of an aligned second board from an opposite side; and (iii) a router guide that receives an guides a finger joint tool of a hand router along a transverse direction to the first and second board guides to simultaneously impart finger joint grooves. A clamping mechanism selectively clamps the first and second boards respectively within the first and second board guides.

This invention relates to a process for the division of an individual input source log into discrete longitudinal lengths for subsequent processing. The process comprises receiving an individual input source log, dividing the input source log into one or a plurality of output log portions of a predetermined length, wherein at least a portion of said output log portions resultant from said division are of a substantially equal or substantially constant or consistent longitudinal length, and wherein said substantially equal or substantially constant or consistent longitudinal length output log portions are procured as a feed stream of log material for a subsequent processing step. This process provides for the processing of logs and subsequent assembly into an end product formed from a composite of sticks derived from said processed logs.
