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.

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.

Centering Spindle
6. Use a caliper to measure the diameter of the
dividing head center where the edge finder
made correct contact.
Whether the spindle of the dividing head is
mounted horizontally or vertically, you must center
the dividing head spindle with the mill spindle to
achieve the most precise results.
We have included two methods to center the spindles below, one for each orientation. However,
there are many ways to center the spindles, and
it is up to the machinist to know their capabilities
and to decide which approach is best.
Horizontal Spindle
1. Make sure the dividing head is properly
aligned with the mill table and firmly secured
in position.
2. Mount the included dead center into the dividing head spindle and an edge finder into the
mill spindle, then move the mill table to position the edge finder in front of the center, as
shown in Figure 7.
7. Add half the diameter of the center and half
the diameter of the edge finder together,
then move the mill table in toward the mill an
additional distance equal to the calculated
number above.
Vertical Spindle
1. DISCONNECT MILL FROM POWER!
2. Make sure the dividing head is properly
aligned with the mill table and firmly secured
in position.
3. Mount a test indicator in the mill spindle and
position the indicator tip against the inside
wall of the dividing head spindle bore, as
shown in Figure 8.
Edge
Finder
Figure 7. Aligning the spindles using an edge
finder.
3. Set the mill for the slowest spindle speed,
then turn the mill ON.
4. Carefully and slowly move the table in-andout along the Y-axis until you find the edge of
the dividing head center.
5. Note the Y-axis position of the mill table.
Note: When recording the mill table position,
take into account the backlash that is usually
present in the leadscrew.
Figure 8. Indicating the spindle bore.
4. Slowly rotate the mill spindle by hand and
watch the test indicator dial.
Note: For best results, turn the spindle in only
one direction.
Tip: Use a mirror to view the indicator dial as
it turns away from you.
5. Slowly adjust the mill table to adjust for the
runout as shown on the indicator.
6. The spindles of the dividing head and mill
are centered with one another when the test
indicator shows zero runout when rotated a
full 360°.

Center Dog
Chuck Backing Plate
When supporting the workpiece between centers,
it is necessary to use the center dog (sometimes
referred to as a drive bracket). The center dog that
is supplied with your dividing head is designed
to mount onto the included dead center and will
require the use of a bent-tail lathe dog (not provided) installed onto the workpiece.
To mount a workpiece between centers:
1. DISCONNECT MILL FROM POWER!
2. Loosen the middle hex nut on the center dog
until it clears the bore, slide it onto the dead
center, then re-tighten the hex bolt to secure
it in place, as shown in Figure 17.
A chuck backing plate is included with your dividing head for mounting a lathe chuck, as shown in
Figure 18.
Run True
Set Screw
Figure 18. Model G9856 6-jaw run true chuck
installed (Model G1054 only).
Follow these rules when mounting a chuck
onto your dividing head:
Figure 17. Workpiece installed between centers.
3. Install the lathe dog onto the workpiece with
the tail extending beyond the end of it.
4. Align the lathe dog tail with a side slot of
the center dog, then properly mount the
workpiece between the centers.
5. Tighten the two hex bolts on the center dog
so that they firmly hold the lathe dog tail.
Note: It may be necessary to alter the lathe
dog tail so that the hex bolts make contact
with two flat surfaces.
6. Make adjustments as necessary to ensure
that the workpiece does not rotate independently of the dead center.
• The backing plate must be mounted on a
lathe with a threaded mandrel, then faced
and shouldered.
• Make the new shoulder a "press fit" with the
chuck to maximize accuracy.
• Correctly drill holes into the backing plate to
accept the mounting of the chuck.
• For maximum accuracy when using the Model
G1054, a run true chuck should be used,
such as the Grizzly G9856 shown in Figure
18. This chuck has four set screws that allow
the center line of the chuck to be correctly
aligned with the center line of the dividing
head spindle.
Note: If you are using a run true chuck, a
press fit is not necessary.

Setting Index Pin
The index pin on the end of the hand crank can
be repositioned to any of the six hole circles on
the dividing plate (see Figure 19). The index pin
is spring loaded so that it will stay engaged with
the current hole.

2. Slightly loosen the crank cap screw, adjust
the crank arm on the shaft until the index pin
is aligned with the required hole circle on the
dividing plate, then re-tighten the cap screw.
Note: Because the index pin is spring loaded,
it will tend to push the crank arm out when the
cap screw is not tightened. As you re-tighten
the cap screw, push in on the crank arm so
that it stays flat against the shaft shoulder.
Using Dividing
Plates
Your dividing head includes three dividing plates,
each having six hole circles in the following patterns:
Plate Number of Holes Per Circle
Plate A ................................ 15, 16, 17, 18, 19, 20
Plate B ................................ 21, 23, 27, 29, 31, 33
Plate C ................................ 37, 39, 41, 43, 47, 49
Tools Needed Qty
Hex Wrench 5mm .............................................. 1
To set the index pin:
1. Pull the crank handle out to disengage the
index pin, then rotate the crank until it is
aligned with the numbered row on the dividing plate (see Figure 20).
All divisions from 1 to 50 can be made with one
of the three plates provided. However, not all of
the divisions from 51 to 100 are capable with your
dividing head, as noted with a "—" in the charts
on the next page.
The dividing charts on Page 17 are set up with
three rows and one column for each division.
Refer to the charts and the following descriptions
to understand the numbers in the rows.
D – Division: The number of stops required for
the machining operation.
H – Hole Circle: The number of the hole circle on
the dividing plate required for the division.
R – Rotations of the Crank Handle: The num-
ber of crank handle rotations required for the
division.

Example
To better understand how to properly use the
dividing plates, perform the instructions in the
example below.
In this example, you will set up the dividing
head for 18 divisions:
6. Position the left sector arm up against the
index pin.
7. Move the right sector arm clockwise so that
there are four holes showing in the 18 hole
circle between the arms, as shown in Figure
22.
1. Locate division 18 in the charts on the pre-
vious page, then note the number directly
below it, which is the required hole circle. In
this case, the hole circle is 18.
2. Install the dividing plate with the 18 hole
circle on the dividing plate, as instructed in
the Changing Dividing Plates section on
Page 13.
3. Loosen the sector arm cap screw, spread the
sector arms apart so that you can position
the index pin of the crank handle between
the sector arms and in a hole of the 18 hole
circle, as shown in Figure 21.
Note: Do not count the hole that the index pin
is in.
Figure 22. Sector arms correctly spread apart
four holes on the 18 hole circle.
8. Tighten the sector arm cap screw to secure
the arms in place and to preserve the correct
4-hole spacing.
Figure 21. Index pin between the sector arms
and seated in the 18 hole circle.
4. Make sure the crank cap screw is fully tightened to firmly secure the crank on the shaft.
5. Look at the division 18 column of the chart
again and note the number in the third row
4
below it. In this case the number is 2
⁄18,
which means the crank handle will be rotated
4
two full turns and
⁄18, or 4 holes, of the third
rotation for each machining cycle after the
first one.
9. Eliminate the backlash in the crank by pulling
the crank handle out to disengage the index
1
pin, rotating the crank
⁄2 counterclockwise
turn, then turning it clockwise and engaging
the index pin with the hole it was in before.
Note: To ensure accurate indexing, it is
imperative that the crank index pin does not
make contact with the sector arms as you
rotate the crank so that the sector arms do
not move from their correct locations.
-18-
Model G1053/G1054 (Mfg. 1/09+)
10. Lock the spindle in place and perform the
machining operation.
11. Without moving the sector arms, pull the
crank handle out to disengage the index pin
and carefully rotate the crank two full turns
clockwise back to the position it started in.
Divisions Beyond 100
In the event that divisions beyond 100 are required,
you can usually find the correct hole circle number
to use by dividing the number of divisions by the
number of the hole circles available on the dividing plates until the answer is a whole number
(without a fraction or decimal).
12. Continue to rotate the crank clockwise until
you can engage the index pin into the hole
that is next to the right sector arm. You have
now rotated the crank handle the required
4
⁄18 turns, as shown in Figure 23.
2
Note: If you move the crank index pin beyond
the final hole, it is crucial to the operation that
you eliminate the crank backlash again, as
explained in Step 9.
Figure 23. Crank position after 2 4⁄18 rotations.
13. While keeping the sector arm cap screw tight,
rotate the sector arms clockwise so that the
left sector arm is up against the crank index
pin and the right arm has moved an additional
4 holes.
Note: If the sector arm cap screw is loos-
ened, the arms will move independently from
one another and the 4-hole spacing will be
changed.
For example, for a division of 115, dividing the
number 23 into 115 gives the answer of 5, a whole
number. This means that the dividing plate with
the 23 hole circle can be used.
The rotation of the crank for each division will
always be less than one full turn for divisions
beyond 40. The amount of holes on the required
hole circle that the crank must be moved can be
found with the following formula:
R = (H x 40) / D
where R is the number of holes between the sector arms, H is the number of the required hole
circle, 40 is a constant that represents the number
of full crank rotations necessary to complete one
revolution of the spindle, and D is the number of
divisions required for the operation.
To continue the example given above, if the number of divisions needed is 115 and the number of
the dividing plate hole circle is 23, then the number of holes that the sector arms must be separated per division is 8, as calculated below:
R = (23 x 40) / 115
R = 920 / 115
R = 8
Note: As in the divisions between 50 and 100,
not all divisions beyond 100 are possible with your
dividing head.
14. Repeat Steps 9–13 until the dividing spindle
and workpiece have made one full revolution.

Use the following tips to help ensure a trouble-free dividing head operation:
Disengaging Worm
• Because the scale on the direct indexing
plate mounted on the dividing head spindle
is oriented clockwise, always rotate the crank
clockwise to make it easier to keep track of
the spindle orientation during the operation.
• Take the time to create a quick-reference
chart when divisions are complex. Using this
chart to compare with the degree scale and
check off as you change locations will reduce
unnecessary mistakes.
• As in most operations, it is a good idea to
perform a test-run before actually making the
cuts, especially before machining an expensive part. Test your dividing setup by running
the complete progression of settings and
turns without actually machining the part.
For example, when performing a test-run for
the previous example, the spindle should
return to its original position after running
the 18 positions. This can be verified by noting the location of the spindle on the degree
scale before and after the test-run. Also, you
can score the part at each division stop to
make sure the cuts will be in the required
locations, as shown in Figure 24.
The worm gear and wheel drive the spindle when
the crank is rotated and these gears are engaged.
They can be disengaged to rotate the spindle by
hand for quick direct indexing.

To disengage the worm gear and wheel:
1. Remove the crank handle, sector spring, sec-
tor arms, and dividing plate.
2. Loosen the two cap screws that secure the
worm gear hub, rotate it counterclockwise
until you can turn the spindle by hand, then
re-tighten the cap screws (see Figure 25).

Figure 25. Disengaging worm gear and wheel.
To re-engage the worm gear and wheel:
1. Rotate the worm gear hub clockwise until you
feel resistance, then tighten the cap screws.
2. Check the rotation of the spindle with the
crank before reassembling the rest of the
parts. If necessary, re-adjust the rotation of
the worm gear hub so that the crank rotates
freely without excess backlash.
Model G1053/G1054 (Mfg. 1/09+)
Cutting Angles
The dividing head can be used for cutting a specific angle or producing a series of angles, such
as in faceting. Perform the example below to learn
how to use your dividing head for angled cuts.
To produce a hex shape (6-sided) with the
dividing head:
1. Disengage the worm gear and wheel so that
the spindle can be rotated by hand.
2. Rotate the spindle by hand until the zero
point of the degree scale is aligned with the
pointer, as shown in Figure 26.
Note: In the next step, keep in mind that the
direct indexing plate mounted on the spindle
has 24 holes, which is evenly divisible by
6. Each index stop will require that 4 holes
pass by the index pin—i.e., the index pin will
engage the 5
was.
3. Use the direct indexing lever to engage the
pin into the plate hole.
Note: If necessary, rock the plate by hand
until the pin engages the hole, then loosen
the pointer cap screw, adjust it to the zero
mark on the degree scale, and re-tighten the
cap screw to secure it in place.
4. Properly mount the workpiece onto the dividing head.

SECTION 5: MAINTENANCE
Schedule
For optimum performance from your dividing
head, follow this maintenance schedule and refer
to any specific instructions given in this section.
Every 8 Hours of Use:
• Clean and lubricate the tool.
• Dress the surfaces of the tool (Page 24).
• Check/resolve any unsafe condition.
Every 160 Hours of Use:
• Disassemble, clean, and lubricate the worm
gear and wheel (Page 24).
Cleaning
To ensure smooth operation and long life of your
dividing head, it is essential that it is cleaned after
every use and a thin coat of light machine oil is
applied to the surfaces to prevent corrosion.
DO NOT use compressed air to clean your dividing head. This could force chips and swarf to
become lodged between the moving parts and
reduce the life and accuracy of the tool. Instead,
use a stiff-bristled brush to remove the chips and
swarf, then wipe down the surfaces with a clean
shop rag.
Lubrication
Ball Oiler & Oil Port
Wipe off the ball oiler on the head shown in
Figure 31, then use the tip of an oil can to add
one squirt of 30W non-detergent oil to the oiler.
Ball Oiler
Figure 31. Ball oiler on the head.
Open the lid of the oil port on the worm gear hub
shown in Figure 32, then add one squirt of 30W
non-detergent oil to the port. Make sure to close
the lid to keep debris out.

Worm Gear & Wheel
Tools Needed Qty
Hex Wrenches 3, 4, 5mm ......................... 1 Each
Phillips Screwdriver #2 ...................................... 1
To lubricate the worm gear and wheel:
1. Remove the crank handle, sector spring, sec-
tor arms, and dividing plate.
2. Remove the two cap screws that secure the
worm gear hub, then remove the hub from
the worm gear shaft, as shown in Figure 33.
Surface Care
Nicks, dings, and scratches on the surfaces of
the dividing head and mill table can have an
adverse effect on accuracy and may damage the
workpiece or mill table.
Prior to use, dress or "stone" these surfaces with
a fine sharpening stone until they are smooth. A
few strokes of the stone on the mill table surface
and the machined surfaces of the dividing head
will help to ensure machining accuracy.

3. Use a stiff-bristled brush, shop rags, and
mineral spirits to clean away the old grease
and grime. When dry, apply a light coat of
medium bearing grease, then re-install the
parts.
Make sure to thoroughly wipe these surfaces
clean to remove any dust generated from the process, then re-apply a thin coat of light machine oil
to prevent corrosion.

Bearing Preload
The spindle in the dividing head is mounted
with tapered roller bearings. The preload on
these bearings was set at the factory and should
never need adjusting. However, if you experience
excess play in the spindle, you can adjust the
spindle bearing preload.
Testing Spindle Play
1. DISCONNECT MILL FROM POWER!
2. Firmly mount the dividing head to the mill
table.
4. Loosen the set screw on the spanner nut
shown in Figure 34.
Set Screw
Spanner Nut
Figure 34. Spanner nut and set screw.
3. Mount a test indicator in the mill spindle and
rest the indicator tip on the top of the spindle
nose.
4. While watching the indicator dial, attempt to
lift the spindle up.
— If the test indicator shows zero deviation
as you attempt to lift the spindle up, there
is no spindle play and the bearing preload
is sufficient.
— If the indicator shows a deviation when you
attempt to lift the spindle up, there is not
enough bearing preload. Continue to the
next subsection to adjust the preload.
Adjusting Bearing Preload
Tools Needed Qty
Hex Wrench 3mm .............................................. 1
Hammer & Punch ..................................... 1 Each
Dead Blow Hammer .......................................... 1
To adjust the bearing preload:
5. Rotate the spanner nut counterclockwise one
full turn, then tap on it with the dead blow
hammer to release the bearing preload.
6. Position a test indicator so that the indicator
tip is touching the front end of the spindle.
7. While watching the test indicator, rotate the
spanner nut clockwise until the indicator dial
stops moving.
Note: By accurately performing this step, you
have reached the zero preload point, which
means that all of the slack has been taken up
between the bearings, seats, and spindle.
