Abstract

Abstract Guide frame means for portable powered saws and including a retainer means comprising a generally "U" shaped frame member having a pair of opposed lateral legs and a first cross-member extending between said opposed legs. An edge guide is coupled between said legs in opposed relationship to the cross-member, with the edge guide having a inwardly facing edge with an inwardly extending flange overlying the inwardly facing edge. Saw cradle means are mounted for adjustable positioning along the laterally extending legs, with the saw cradle means having an opening formed therein to accommodate a saw blade. Castor support means are mounted on the cross-member and are arranged to support the guide frame means at an elevation substantially along a plane through the work supporting surface of the inwardly extending flange.
