Indexing
Indexing on a lathe is typically used for workpiece
layout and other auxiliary operations that require
equal distances around the workpiece circumfer-
ence, such as clock faces or inlays.
By inserting the indexing pin knob into one of the
24 indexes on the spindle housing, the workpiece
can be positioned in 15° increments, as shown in
Figure 25.
Always DISCONNECT LATHE FROM POWER
before using indexing feature. DO NOT start
lathe with indexing pin knob inserted into
spindle; otherwise entanglement injury and
property damage could occur.
