A power-operated hand tool has a handle portion or frame that is gripped by the operator using two hands. A clamping portion comprising a pair of opposed jaws extends outwardly from the handle portion and utilizes an air cylinder to move an upper clamping jaw toward and away from the lower fixed jaw. Both jaws have free outermost ends that cooperatively define an entry mouth into a clamping zone between the jaws. In use, a group of individual boards are laid side-by-side in edge-to-edge relationship slightly above a work surface so as to permit the lower jaw of the tool to be slipped beneath the boards while the upper jaw becomes placed above the boards, both of which extend transversely across the boards. Upon actuation of the air cylinder, the upper jaw comes down into flattening engagement with the boards, causing them to be clamped down into generally flat alignment with one another in a common plane so as to present a substantially smooth top surface. Thereupon, the panel may be squeezed tightly from the side by bar clamps or the like to shift the flattened boards into tight abutting engagement with one another before the air cylinder is deactuated and the tool is removed.
