ABSTRACT:
An apparatus and a method for producing accurate straight cuts in a slab of stone, concrete, or the like. A carriage conveys the cutter along two parallel rails that lie directly upon the upper surface of the slab to be cut. In a preferred embodiment of the invention, neither rail is connected to anything else, and a sheet of resilient material is bonded to the underside of each rail. A calibration instrument is disclosed, which is used to facilitate spacing the rails specific distances on either side of the desired cut line. Because the rails can be moved one at a time in the preferred embodiment, the apparatus is highly portable. In an alternative embodiment in which portability is not an important consideration, the rails may be permanently connected by rigid lateral members.
