IMPORTANT: When the workpiece (A) is long enough,
position it on the table with one end against the left side
of the column (B) to prevent the workpiece from rotat-
ing. See Figure 15-1. if it is not possible to support the
workpiece against the column, clamp the workpiece to
the table. A vise can be used to secure a small work-
piece that is too small to be clamped to the table. The
vise must be secured to the table to keep it from rotat-
ing. If you are using a backup board, it must also be
properly supported or clamped.
