Abstract
Disclosed herein is a lumber torque tool used for straightening of warped lumber during the fabrication of wood frame assemblies. This warpage is known as crook and twist. The lumber torque tool comprises: an elongate lever arm comprising an inner lever face, an alignment plate comprising a medial face facing and spaced from the inner lever face, and a torque link extending and fixed between the medial face and the inner lever face. The inner lever face, the medial face and the torque link define a proximally facing U-shaped proximal lock pocket and a U-shaped distal lock pocket at a distal end of the lumber torque tool for engaging lumber therein during the application of forces to the lumber. Methods for using the lumber torque tool to remove twist and crook are described.

A tool for straightening warpage in lumber comprising:
- an elongate lever arm operable to apply hand forces at a proximal end of said elongate lever arm and transmit said forces on a portion of lumber at a distal end of said lever arm;
- said elongate lever arm comprising an inner lever face;
- an alignment plate;
- said alignment plate comprising a medial face facing and spaced from said inner lever face;
- a torque link;
- said torque link having a proximally facing proximal edge;
- said torque link having a distal surface facing distally;
- said torque link extending between said medial face and said inner lever face;
- a distal leg of said elongate lever arm extending distally past said torque link;
- said distal leg having a length exceeding the length of said distal surface of said torque link;
- said inner lever face, said medial face, and said proximal edge define a U-shaped proximal torque pocket that opens proximally and is operable to seat a portion of lumber therein and apply torque to induce straightening of said lumber using said elongate lever arm;
- and,
- wherein said inner lever face, said medial face, and said distal surface define a U-shaped distal torque pocket that opens distally and is operable to seat a portion of lumber therein and apply torque to induce straightening of said lumber using said elongate lever arm.
A tool for straightening warpage in lumber comprising:
- an elongate lever arm;
- said elongate lever arm having a handle at a proximal end operable to apply hand forces to transmit said hand forces on a portion of lumber engaged at a distal end of said lever arm;
- said elongate lever arm comprising an inner lever face;
- an alignment plate;
- said alignment plate comprising a medial face facing and spaced from said inner lever face;
- a torque link;
- said torque link having a proximally facing proximal edge;
- said torque link having a distal surface facing distally;
- said torque link extending between said medial face and said inner lever face;
- a distal leg of said elongate lever arm extending distally past said torque link;
- said distal leg having a length exceeding the length of said distal surface of said torque link;
- said inner lever face, said medial face, and said proximal edge define a U-shaped proximal torque pocket that opens proximally and is operable to seat a portion of lumber therein and apply torque to induce straightening of said lumber using said elongate lever arm;
- said inner lever face, said medial face, and said distal surface define a U-shaped distal torque pocket that opens distally and is operable to seat a portion of lumber therein and apply torque to induce straightening of said lumber using said elongate lever arm;
- and, wherein said elongate lever arm, said torque link, and said alignment plate are inseparable.
