This manual provides critical safety instructions on the proper setup,
operation, maintenance, and service of this machine/tool. Save this
document, refer to it often, and use it to instruct other operators.

Failure to read, understand and follow the instructions in this manual
may result in fire or serious personal injury—including amputation,
electrocution, or death.

The owner of this machine/tool is solely responsible for its safe use.
This responsibility includes but is not limited to proper installation in
a safe environment, personnel training and usage authorization,
proper inspection and maintenance, manual availability and compre­hension, application of safety devices, cutting/sanding/grinding tool
integrity, and the usage of personal protective equipment.

The manufacturer will not be held liable for injury or property damage
from negligence, improper training, machine modifications or misuse.

Some dust created by power sanding, sawing, grinding, drilling, and
other construction activities contains chemicals known to the State
of California to cause cancer, birth defects or other reproductive
harm. Some examples of these chemicals are:

• Lead from lead-based paints.

• Crystalline silica from bricks, cement and other masonry products.

• Arsenic and chromium from chemically-treated lumber.

Your risk from these exposures varies, depending on how often you
do this type of work. To reduce your exposure to these chemicals:
Work in a well ventilated area, and work with approved safety equip­ment, such as those dust masks that are specially designed to filter
out microscopic particles.

Description

The Model G1053/G1054 Dividing Head offers
precision rotary positioning of the workpiece for
machining various spacing patterns.

A pattern of drilled holes radially or on the face
of the workpiece may be produced with exact
spacing. Other typical operations include milling
of spur gears, sprockets, cogs, and circular slots,
as well as, grinding punches or other hardened
materials. These tasks would be difficult to per­form without the use of a dividing head.

This dividing head is supplied with a 24-hole
direct indexing plate and index system that allows
divisions of 2, 3, 4, 6, 8, 12, and 24.

SECTION 1: SAFETY

For Your Own Safety, Read Instruction

Manual Before Operating This Machine

The purpose of safety symbols is to attract your attention to possible hazardous conditions.
This manual uses a series of symbols and signal words intended to convey the level of impor­tance of the safety messages. The progression of symbols is described below. Remember that
safety messages by themselves do not eliminate danger and are not a substitute for proper
accident prevention measures. Always use common sense and good judgment.

Indicates an imminently hazardous situation which, if not avoided,
WILL result in death or serious injury.

Indicates a potentially hazardous situation which, if not avoided,
COULD result in death or serious injury.

Indicates a potentially hazardous situation which, if not avoided,
MAY result in minor or moderate injury. It may also be used to alert
against unsafe practices.

This symbol is used to alert the user to useful information about

proper operation of the machine.

Safety Instructions for Machinery

OWNER’S MANUAL. Read and understand this
owner’s manual BEFORE using machine.

TRAINED OPERATORS ONLY. Untrained oper­ators have a higher risk of being hurt or killed.
Only allow trained/supervised people to use this
machine. When machine is not being used, dis­connect power, remove switch keys, or lock-out
machine to prevent unauthorized use—especially
around children. Make workshop kid proof!

DANGEROUS ENVIRONMENTS. Do not use
machinery in areas that are wet, cluttered, or have
poor lighting. Operating machinery in these areas
greatly increases the risk of accidents and injury.

MENTAL ALERTNESS REQUIRED. Full mental
alertness is required for safe operation of machin­ery. Never operate under the influence of drugs or
alcohol, when tired, or when distracted.

ELECTRICAL EQUIPMENT INJURY RISKS. You
can be shocked, burned, or killed by touching live
electrical components or improperly grounded
machinery. To reduce this risk, only allow qualified
service personnel to do electrical installation or
repair work, and always disconnect power before
accessing or exposing electrical equipment.

DISCONNECT POWER FIRST.
nect machine from power supply BEFORE making
adjustments, changing tooling, or servicing machine.
This prevents an injury risk from unintended startup
or contact with live electrical components.

EYE PROTECTION. Always wear ANSI-approved
safety glasses or a face shield when operating or
observing machinery to reduce the risk of eye
injury or blindness from flying particles. Everyday
eyeglasses are not approved safety glasses.

Always discon-

The unpainted surfaces are coated with a waxy
oil to prevent corrosion during shipment. Remove
this protective coating with a solvent cleaner or
degreaser, such as shown in Figure 3. For thor­ough cleaning, some parts must be removed.

For optimum performance, clean all moving
parts or sliding contact surfaces. Avoid chlo-

rine-based solvents, such as acetone or brake
parts cleaner that may damage painted surfac­es. Always follow the manufacturer’s instructions
when using any type of cleaning product.

Gasoline and petroleum
products have low flash
points and can explode
or cause fire if used to
clean machinery. DO
NOT use these products
to clean the machinery.

Installation

Before installing the dividing head or tailstock,
make sure that your mill table and spindle are
properly aligned as instructed in the owner's
manual for your mill. Remove any surface burrs
or scratches from the mating surfaces of the mill
table, the dividing head, and the tailstock by "ston­ing" them, then thoroughly wipe them clean and
dry (refer to the Surface Care section on Page 24
for detailed instructions).

3. While aligning the keys with the center T-slot
of the table, place the dividing head on the
table with the spindle facing to the right, then
secure it with the appropriate clamping hard­ware (see Figure 5).

The dividing head and tailstock have keyways
machined into the bottom of their mounting bases,
which measure 16mm or approximately 0.6299".
Making alignment keys that fit these keyways and
the T-slot of the mill table provides a convenient
and efficient way to ensure alignment of the divid­ing head and tailstock with the mill table X-axis.

Note: The dividing head and tailstock install in the
same manner.

Installing with Alignment Keys

1. DISCONNECT MILL FROM POWER!

2. Install the alignment keys into the base of the

dividing head, as shown in Figure 4.

x 2

Spindle

Figure 5. Tool installed on the mill table.

Installing Without Alignment Keys

1. DISCONNECT MILL FROM POWER!

2. Place the dividing head in the center of the

mill table with the spindle facing to the right.

3. Mount a test indicator into the mill spindle
with the indicator tip touching the front face
of the dividing head, as shown in Figure 6.

moving the mill table back-and-forth along
the X-axis until the indicator reads zero devi­ation across the face, then clamp the head in
place.
