Abstract
An apparatus is disclosed for woodworking and like applications to clamp structural members in abutting relation by initial formation of a pair of recesses in the structural members on a common imaginary line perpendicular to the intended joint line. The clamping apparatus has two clamping members each having an outwardly projecting engagement portion configured to fit securely in the recesses and a clamping mechanism actuable to move the clamping members and their engagement portions toward and away from one another for clamping movement along a clamping line coinciding with the imaginary line perpendicular to the intended joint line. The clamping apparatus may be used in forming virtually any edgewise abutting joint between respective structural members, e.g., miter joints, butt joints, linear edge joints, and radius edge joints.
