SPINDLE INDEXING ADJUSTMENTS
The Headstock Spindle has 12 indexing holes, each 30°
apart, which allows accurate pattern work on projects such
as straight fluting, grooving, drilling, detail carving, wood
burning patterns, laying out designs and more.
In addition to the 12 indexing holes in the spindle, there are
three positioning holes located in the headstock casting,
behind the spindle. FIG. 16. These three holes (A, B, C),
which accept the indexing pin, are 20° apart. The combi-
nation of these 15 total holes will allow you to mark your
workpiece for evenly spaced features up to 36 positions.
The Indexing Chart, below, shows how to rotate the spindle
to access any of the 12 indexing holes, as well as using
the three headstock position holes to increase the indexing
possibilities up to 36 settings. The 11 primary settings are
listed, however, other indexing/design settings are possible.
Insert the Indexing Pin (#B10) into one of these three
headstock positioning holes according to the chart, and
the number of setting you need for your workpiece. Make
sure that the pin locates and securely enters into one of the
indexing holes so that there is no accidental slipping.

* Indexing for 8 and 24 positions requires that the first sequence of settings (A) are made, then the
workpiece has to be rotated into position on the lathe for the remaining indexing to be done.
NEVER START THE LATHE WITH
THE INDEX PIN ENGAGED IN THE SPINDLE, OR
DAMAGE TO THE MACHINE WILL RESULT.
NOTE:
The 9,18 and 36 indexing positions require three
settings (A, B, C) with the headstock holes. Set the Index-
ing Pin in the ‘A’ setting and then do your work, rotating
the spindle to the index settings noted on the chart. Once
done, move the index pin to the headstock ‘B’ setting and
work through the next index setting number positions.
Finally, move the index pin to the headstock ‘C’ setting and
complete the remaining work with the workpiece rotated to
the last spindle index numbers indicated.
