ABSTRACT:
A combined sheet bending brake and platform comprising a base, first and second bending members hinged to one another, an anvil member for clamping a work piece of sheet material on the first member such that moving the second member relative to the first member will bend the sheet material and a platform extending longitudinally for at least a portion of the length of the sheet bending brakes along the base generally parallel and opposite to the hinge axis of the two members such that the area overlying the brake is generally unobstructed.
