Large trim guide
Few of us own tablesaws capable of safely and accurately crosscutting large workpieces. Or do we? Use the saw-table edge as a guide. Clamp a 1 x 6 to the underside of the material the appropriate distance away from, and parallel to, the intended cutoff line. Then, run the material through the saw, using the 1 x 6 as your fence. Use this technique to straighten an uneven edge, too.
