ABSTRACT:
A portable sheet bending brake comprising a base and a plurality of C-shaped members positioned on the base. Each C-shaped member comprises a lower arm fixed to the base and an upper arm spaced from and overlying the lower arm. A first member is fixed to the lower arms of the C-shaped members and has a longitudinally extending clamping surface. A second member for bending a workpiece is hinged to the first member and extends longitudinally with respect to the first member. A longitudinally extending clamping member is pivoted to the upper arm of the C-shaped members. A handle member is provided on the brake for moving the clamping member. A track extends longitudinally on the portable sheet bending brake and a cutter is removably mounted on the track and is movable longitudinally of the track. The cutter comprises opposed cutting rolls adjacent the clamping surface when the cutter is on the track such that the cutter may be moved along the track to cut a workpiece.
