摘要： A pair of uprights are provided and disposed in laterally spaced relation. The uprights are interconnected at their lower ends by a horizontal base projecting considerably rearwardly, only, from the uprights and each of the uprights includes front and rear standards. The front standards support a horizontal fulcrum rest extending therebetween and the rear standards support a horizontal abutment member extending therebetween and vertically ajdustable therealong. The abutment member is disposed at an elevation above the elevation of the fulcrum rest and the outwardly projecting portion of the base includes platform structure from which a considerable weight load as may be represented by large rocks may be supported. Elongated logs to be cut may have short base ends thereof engaged beneath the abutment member and over the fulcrum rest with the opposite longer free ends of the logs projecting considerably outwardly from the side of the uprights remote from the sides thereof from which the base projects. The logs may thus be supported in cantilever fashion with their free ends spaced above the ground for cutting by the operator of a power chain saw or the like.
