Abstract: A horizontally elongated base member is provided as well as a pair of horizontally elongated extension members. The extension members are removably mounted from opposite end portions of the base member in coextensive, longitudinally spaced relation with the spaced adjacent ends of the extension members exposing a center portion of the base member from above and the remote ends of the extension members projecting considerably beyond corresponding ends of the base member. A cut off saw is removably receivable on the center portion of the base member between the adjacent ends of the extension members with the slotted table of the cut off saw coextensive with the upper surfaces of the extension members and, after the cut off saw has been removed, the extension members are detachable from the end portions of the base member, positionable in superposed relation and resecurable in position overlying the base member to provide a considerably foreshortened assembly for compact storage and transport.
