A center-less sheet metal bending machine is provided to form cheek bends in a piece of sheet metal. The bending machine includes a housing having a mouth and a table adjacent the housing mouth. A clamping mechanism is provided to hold the sheet metal in place during a bending operation, and a bending mechanism is provided to form a cheek bend in the sheet metal. The clamping mechanism includes a toggle or link driven anvil which is movable between a raised and a lowered position. The bending mechanism includes an elongate bending bar which is mounted in the housing for rotation between a start position and a finished position. In the start position, a forward edge of the bending bar is proximate a rear edge of the anvil. The bending bar is pulled rearwardly and upwardly to rotate it from its start to its finished position to form a bend in a piece of sheet metal.
