A method and apparatus for cutting a boiler tube-wall of a power generating station comprised of a plurality of generally parallel, vertical tubes welded together lengthwise, the method employing a guide having a pair of parallel guide rods interposed between a pair of securement devices for selectively, removably securing the guide to the tube-wall and a mount slidably mounted on the guide rods for movably supporting an actuatable tool for movement along the guide rods between the securement devices, the method comprising the steps of: (a) mounting a cutting tool to the mount; (b) removably securing the guide to a first location on one vertical surface of the tube-wall, the location being defined by a first line of cut to be made in the tube-wall; (c) actuating the cutting tool; and (d) moving the cutting tool along the guide rods between the securement devices and along the first cut line to cut through the tube-wall and any of the tubes therealong.
