LINE BORING
1. Figure 63 illustrates a typical line boring operation
being performed on a workpiece. Note that the right end
of the workpiece is positioned against the fence stop (A)
and 13 holes are being bored with a 32mm center
distance between each hole.

2. If more than 13 holes are required, simply slide
work-piece along the fence and push down on the
indexing pin (B) Fig. 64, until the pointed end of the pin
is in the last hole that was previously bored. This lines up
the workpiece for the next series of holes. Note that the
fence stop (A) has been pushed back allowing the
workpiece to fit flush against the fence.
3. Then bore the additional thirteen holes in the
workpiece, as shown in Fig. 65. All holes are 32mm
apart from each other.
