It is on the right side of the saw. 4. The work table is the support for the material to be cut. A miter gauge slot is formed into the table to cut angles on the saw. The work table also has a fence guide to cut straight lines. The table is also able to tilt for angle cuts. 5. The miter gauge is a guide that will adjust to cut angles and 90 degrees. 6. The fence is a guide for straight cuts and for re-sawing thickness.
