ABSTRACT:
A combination tablesaw top and mitre bar is provided which eliminates the play encountered in previous systems. In addition the manufacturing tolerances are much relaxed, leading to reduced cost and little if no operator adjustment. In a preferred embodiment, the tablesaw has a flat top with a groove therein extending substantially across the top, the groove having a top and a bottom, wherein the groove has a cross-section which is wider at the top than at a point below the top. The mitre bar for use with the tablesaw has a top and a bottom, and a cross-section such that the top of the mitre bar is larger in dimension than the lateral dimension of the bottom of the mitre bar, but the top of the mitre bar is smaller in dimension than the top of the tablesaw groove. This relationship between the groove and the mitre bar is provided such that the mitre bar will sit down into the groove without extending above the tablesaw top. Several preferred embodiments are described.
