Joint construction and method of making same

A method of joining a first workpiece having a first surface and a second surface angularly disposed relative to said first surface, and a second workpiece having a surface disposable in abutting relation relative to said second surface of said first workpiece, comprising:

• forming an elongated recess in said first surface of said first workpiece, sloped toward and spaced from said second surface of said first workpiece, producing an end surface thereof disposed at an angle relative to a longitudinal centerline of said recess;
• forming a notched ledge on said end surface of said recess;
• positioning a threaded fastener in said elongated recess with a head portion thereof resting on a bottom surface of said recess and the threaded portion thereof disposed along said longitudinal centerline with the end thereof resting on said ledge;
• disposing said surface of said second workpiece in abutting relation with said second surface of said first workpiece;
• and
• threading said threaded fastener along said longitudinal centerline of said recess, through said abutting surfaces of said workpieces to join said abutting workpieces together,
• wherein said ledge provides a support surface for an end of the shank portion of a fastener disposed in said recess along said centerline,
• wherein the method further includes forming said elongated recess with a machine tool provided with a first cutting tool indexed simultaneously along a Z-axis disposed orthogonally relative to said first surface of said workpiece and an x-axis disposed parallel to said first surface of said first workpiece to form said elongated recess, and forming said ledge with a second cutting tool of said machine tool advanced along said z-axis.

A method of forming an assembly including a first workpiece having a first surface and a second surface disposed angularly relative to said first surface, and a second workpiece having a mating surface disposed in abutting relation relative to said second surface of said first workpiece, the method comprising:

• forming an elongated recess in said first surface of said first workpiece, sloped toward and spaced from said second surface of said first workpiece, producing an end surface thereof disposed at an angle relative to a longitudinal centerline of said recess, wherein said elongated recess is formed with a machine tool provided with a first cutting tool indexed simultaneously along a Z-axis disposed orthogonally relative to said first surface of said first workpiece and an X-axis disposed parallel to said first surface of said first workpiece to form said elongated recess;
• forming a notched ledge on said end surface of said recess, wherein said ledge is formed with a second cutting tool of said machine tool advanced along said Z-axis, wherein the second cutting tool is different from the first cutting tool;
• positioning a threaded fastener in said elongated recess with a head portion thereof resting on a bottom end of said elongated recess and the threaded portion thereof disposed along said longitudinal centerline with the end thereof resting on said ledge;
• disposing said mating surface of said second workpiece in abutting relation with said second surface of said first workpiece;
• and
• threading said threaded fastener along said longitudinal centerline of said elongated recess, through said second surface of said first workpiece and said mating surface of said second workpiece, to secure said abutting workpieces together.

A joint construction comprising:

• a first workpiece provided with a first surface, a second surface disposed at an angle relative to said first surface, a sloped recess disposed in said first surface having a longitudinal centerline extending through said second surface and a ledge formed on an end wall of said sloped recess, wherein said longitudinal centerline intersects said sloped recess;
• a second workpiece provided with a surface abutting said second surface of said first workpiece;
• and
• a threaded fastener inserted through said sloped recess along said longitudinal centerline, having a threaded portion thereof with an end thereof resting on said ledge, threaded through the abutting surfaces of said workpieces, with a head portion engaging the end surface of said recess.
