Abstract
A composite wood product manufactured from waney lumber and a method for making the composite wood product. The method utilizes lumber that has been cut from a log such that the piece has a length substantially parallel to the longitudinal axis, a width substantially tangential to the growth rings and a thickness substantially perpendicular to the growth rings. The wane on the lumber is removed to create a complementary side surface for joining in alternating growth ring orientation to the adjoining piece across the joined profiled side surfaces.
Claims31
A method of making a composite wood product comprising joining complementary profiled side surfaces of two waney pieces of lumber, wherein each piece of lumber has been cut from a log, the log having growth rings concentrically arranged radially about a longitudinal axis of the log from an inner pith to an outer bark, so that the piece has a length substantially parallel to the longitudinal axis, a width substantially tangential to the growth rings and a thickness substantially perpendicular to the growth rings, with a top surface of the piece being towards the outer bark with respect to a bottom surface of the piece being towards the inner pith, the top surface and the bottom surface defining the thickness of the piece, and a left side surface and a right side surface defining the width of the piece, wherein at least one of the side surfaces of the piece is profiled to remove a wane to provide the complementary profiled side surface for joining;
- and, the pieces of lumber are joined in opposite orientation with the top surface of one piece adjacent to the bottom surface of the adjoining piece across the joined profiled side surfaces.
A composite wood product comprising at least two pieces of waney lumber joined at complementary profiled side surfaces, wherein the composite wood product comprises at least two pieces of lumber, wherein each piece of lumber has been cut from a log, the log having growth rings concentrically arranged radially about a longitudinal axis of the log from an inner pith to an outer bark, so that each piece has a length substantially parallel to the longitudinal axis, a width substantially tangential to the growth rings and a thickness substantially perpendicular to the growth rings, with a top surface of the piece being towards the outer bark with respect to a bottom surface of the piece being towards the inner pith, the top surface and the bottom surface of each piece defining the thickness of the piece, and a left side surface and a right side surface of each piece defining the width of the piece, wherein at least one of the side surfaces of each piece is profiled to remove a wane to provide the complementary profiled side surfaces for joining the pieces;
- and, the pieces of lumber are joined in opposite orientation with the top surface of one piece adjacent to the bottom surface of the adjoining piece across the joined profiled side surfaces.
A method of milling wood, comprising cutting a piece of lumber from a log, the log having growth rings concentrically arranged radially about a longitudinal axis of the log from an inner pith to an outer bark, so that the piece has a length substantially parallel to the longitudinal axis, a width substantially tangential to the growth rings and a thickness substantially perpendicular to the growth rings, with a top surface of the piece being towards the outer bark with respect to a bottom surface of the piece being towards the inner pith, the top surface and the bottom surface defining the thickness of the piece, and a left side of the piece and a right side of the piece defining the width of the piece, wherein at least one of the sides of the piece is profiled to remove a wane to provide a profiled side, and the profiled side comprises a series of right-angled steps disposed diagonally across the thickness of the piece.
