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.

Abstract: A bull nose corner marking apparatus includes a body having a first section and a second section joined perpendicularly relative to one another for placing about an outside corner of a wall. The first section and second section define an internal area corresponding to the shape of a bull nose corner end molding piece. Through utilization of the marking apparatus, proper markings can quickly be made on an outside corner of a wall. In addition, a bull nose corner end molding piece can be quickly measured and marked for completing the construction of a bull nose corner molding location.
