Radial
holes into the edge of circular workpieces can be bored accurately
by working as shown in Figure
11-16. This procedure is known as pivot boring. A strip
of wood, sized to fit the table slot and with a short nail
driven through it at an approximate midpoint, is clamped to
the table so the nail is aligned with the spindle's center.
The workpiece, marked off in degrees for the holes that are
required, is centered over the pivot nail and rotated to position
it for each hole. Set the depth control to limit quill extension.
