16.6.4. Locking Handles
Each small locking handle such as D, Figure 13 can be rotated to
a more convenient position. Simply lift up on the handle, rotate
it on the pin, then release it, making sure it seats itself on the
pin.
16.6.5. Live Center & Cone
The live center cone, shown in Figure 14, screws clockwise onto
the threads of the live center body.
To remove the cone from the live center, first insert the live
center pin through the hole in the live center body as shown in
Figure 14. If the pin will not insert at first, rotate the cone until
the pin can be inserted. The cone can now be removed by
holding the body stationary while unscrewing the cone.
16.6.6. Indexer
The indexer allows you to cut evenly spaced features in a
workpiece while keeping the Lathe headstock spindle locked;
for example, when cutting flutes on a spindle blank with a
router, while the spindle blank is secured within the Lathe
centers.
There are 12 holes in the spindle collar spaced 30° apart, and 4
holes in the headstock casting which accept the index pin (see
Figures 15 & 16). The combination of holes will allow you to
mark your workpiece for evenly spaced features.
a. To use the indexer, thread the index pin (Figure 15) into
one of the four holes until the index pin engages the
spindle and prevents it from turning. This will be your
first indexing position.
b. Unscrew and remove the index pin, and look down the
hole, carefully counting the number of holes as you
rotate the spindle using the handwheel. Continue to
rotate the spindle until you reach the hole needed for
your second flute cutting, then re-insert the index pin.
c. Refer to the more detailed instructions and chart in the
Powermatic Manual (available at the Monitor’s Desk) to
determine in which holes to place the index pin relative
to the number of flutes desired in your workpiece.
NOTE: Remove index pin before turning on the Lathe.
