By this movement thechuck and piece can be turned end for endin planing straight work. The vise forholding the work is like a stout trough with-out ends, in which slides the movable jawby the screw. This screw has a head at theback side of the chuck, so that in the gripfor holding the work, the screw drawsinstead of pushes.
