OPERATION
TO SUPPORT LONG WORKPIECES
See Figure 29.
Long workpieces need extra supports. Supports should be
placed along the workpiece so it does not sag. The support
should let the workpiece lay flat on the base of the saw and
miter table during the cutting operation. Use the work clamp
or C-clamp to secure the workpiece.
