Live Center and Cone

The live center cone, shown in Figure 17,

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 17. 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.

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 18 and

19). The combination of holes will allow you to

mark your workpiece for evenly spaced features.

1. To use the indexer, thread the index pin

(Figure 18) 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.

2. 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.

3. Refer to the more detailed instructions and

chart on page 28 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.

Centers – Installing and Removing

1. Disconnect Lathe from power source.

2. To install a spur center or live center (the

spur center should first be mounted to your

workpiece; see under “Operation” for more

details), clean the tapered end of the center

and the inside of the headstock taper

spindle, then push the center into the

headstock spindle.
