Abstract: Lumber construction tools that facilitate lifting and manipulating wall sections and discrete structures of the lumber assembly. One of the construction tools discloses a wall lifting appliance or device for raising timber framed wall structures from a horizontal to a vertical position without unduly interfering with placement of sheathing on the framed wall sections. A construction lumber biasing tool is also disclosed that includes a handle portion and a offset portion that cooperate with one another and the lumber members to facilitate deflection or deformation of warped or curved lumber members to achieve the desired orientation of the lumber relative to adjacent members.
