A mobile saw bench (10) is designed for cutting elongate workpieces such as elongate open or closed steel sections. The mobile saw bench (10) comprises a base structure (14) which is mounted on four castor wheels (16). Formed continuous with the base structure (14) is an intervening frame structure (18) to which a benchtop (20) is mounted. The saw (12) is appropriately mounted to the benchtop (20) to permit cutting of a workpiece which is located thereon. Importantly, the mobile saw bench (10) further comprises a universal coupling (22). The universal coupling (22) is mounted to an underside of the benchtop (20) and is releasably clamped to an elongate member (24) which is in the form of a rigid measuring staff. The universal coupling (22) allows pivotal movement of the benchtop (20) relative to the measuring staff (24) which is stationary.
