Abstract
A lumber straightening apparatus includes generally a force application section and a lumber engaging section. In a preferred application, the lumber engaging section is inserted over a stud being secured as part of a stud wall. Force is applied to the force application section to cause a first end of the stud to rotate relative to a second end of the stud. After rotation and upon positioning the first end in proper alignment and orientation relative to a cross piece, the first end is secured to a cross piece in a parallel and square manner relative to the cross piece.
