Abstract: An auxiliary support device for table saws, includes an auxiliary table extending rearward and coplanar of the saw main table. An adjustable guide and support member is mounted at one side of the auxiliary table and can be moved toward and away from the one side. Legs maintain the guide and support member parallel to the tops of the tables. The guide and support member includes a slide extensible in a forward direction, parallel to the main table. The auxiliary table and the sideways movable guide and support member provide extended support beyond the main table for large pieces being trimmed to a smaller width. Extending the slide forward provides outboard support over a space beyond the side of the main saw table, opposite from the saw's fence, where the operator can move into this space during completion of a cut, thereby giving him enhanced control over a large panel or piece of stock.
