ABSTRACT:
A mitre box has a saw guide subassembly rotatably supported on a vertical post and a multiplicity of indents spaced about a portion of its periphery. A wedge member is pivoted on the base member below the saw guide subassembly and is biased to engage an edge portion in one of the indents thereof to prevent its rotation. Positioning means is provided to orient the engagement edge portion of the wedge member in axial alignment with the post to ensure accurate and stable positioning of the subassembly in a predetermined rotated position about the post. The saw guide subassembly may include a fixedly supported saw guide element and a second saw guide element which is carried on the fixed guide element and pivotable relative thereto about a pivot point adjacent the upper edge of the guide elements to equalize the pressure exerted by the ends of the saw guide subassembly on the saw received therebetween.
