The table handwheels and the knee handle have
graduated dials. Each mark represents 0.001" of
movement and one full revolution equals 0.100" The
graduated dials float and can be indexed or "zeroed" by
loosening the knurled head thumb screw, rotating the
graduated dial to "0", and securing the setting with the
knurled head thumb screw (see
Figure
17
).
Example:
Suppose you want to drill a series of holes with 1/2"
centers (0.500"). After locating the first hole placement
and drilling, you would zero the graduated dial of the
appropriate axis, set the knurled head thumb screw,
move the table 0.500" in the appropriate direction and
drill the next hole.
