ABSTRACT:
A portable sheet bending brake comprising a first member defining a clamping surface extending longitudinally, a second member extending longitudinally and hinged to the fixed member, and an anvil member extending longitudinally of the sheet bending brake that is moved into and out of clamping position with the fixed member. A floating compensator comprising a compensator member is pivoted to the bending member and a workpiece engaging pad is pivoted to the compensator member such that as the bending member is swung to bend a workpiece, the pad engages the surface of the workpiece and remains in contact with the workpiece at the same area by the relative pivotal action of the bending member, the compensator member and the pad.
