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 turning assembly used to form at least a portion of a turned object comprises a plurality of prism block segments. The outer face includes a width that is greater than a width of the inner face. A radial central axis extends between and is perpendicular to the outer face and the inner face and has a length greater than the width of the inner face. A first set of block segments is arranged in a side-to-side orientation to form a first turning blank with the outer faces generally forming a regular polygon. A second set of block segments is arranged in a side-to-side orientation to form a second turning blank with the outer faces generally forming a regular polygon. The first turning blank is coupled to the second turning blank to form a coupled turning blank that is formed into the portion of the turned object.

A jig system for trimming of a one or more uncut boards. Said jig system comprises a two halves, a bracket mating system, a one or more male portions, a one or more female sockets, a first end, a second end, a first lathe adapter assembly, and a second lathe adapter assembly. Said two halves comprise a first half and a second half. Said two halves are configured to selectively mate with one another. Said two halves comprises an assembled configuration and a disassembled configuration. Said assembled configuration comprises said two halves mated with one another. Said disassembled configuration comprise said two halves detached from one another. Said two halves comprise an angled irons having a substantially L-shape. Said two halves comprise a bend, an inner sides, an outer sides, a first planar portion and a second planar portion.

Disclosed is a manufacturing method of a composite panel, comprising: a providing step of providing a flexible sheet; an attaching step of forming a lamellar structure by attaching at least one lamellar board to cover the flexible sheet; and a cutting step of cutting a plurality of longitudinal grooves in the lamellar structure layer to form a plurality of lamellar strips, thereby obtaining the composite panel that is able to be bent laterally into a curved configuration.

A stud straightener system and method of straightening studs of a wall structure for a modular construction unit. The wall structure has a wall frame including the studs and one or more sheathing panels on a top side of the wall frame. The stud straightener system includes a wall frame conveyor and a stud straightener assembly. The wall frame conveyor is configured to move the wall structure thereon. The stud straightener assembly includes an actuator assembly having an actuator and a carriage tooling assembly having a clamp tooling assembly. The carriage tooling assembly is configured to move along the actuator to one or more of the studs and the clamp tooling assembly is configured to engage the one or more of the studs to straighten the one or more of the studs.
