Procure an ordinary lag screw, as shown in Fig. 1, cut off the pointed end and file the threads into the shape shown in Fig. 2. A hole is drilled through the head and a handle put in, as shown in Fig. 3. This makes a good substitute screw when the original screw for a small vise is broken. - Contributed by James M.
