INDEXING
The spindle pulley contains 36 equally spaced holes. The
index pin engages with these holes to keep the spindle
from turning while you put a mark on the workpiece.
For example: To locate the position of six spokes in a
wheel:
1, Pull the index pin outward and turn it so that the small
cross pin slips into the slot. This will allow the index
pin toengagein one of the holes in the pulley and pre-
vent the spindle from turning.
2. AdjuSt the toot rest approximately at the centerline
and make a mark.
3, Pull out the index pin and slowly rotate the workpiece
until the pin slides into the next hole in the pulley.
4, Do this six times and put the next mark on the work-
piece, The _wo marks will be spaced 60° apart, Con-
tinue this operation until six spokes are marked 60 °
apart.
5. Spindle turnings can be divided in the samemanner.
