The purpose of safety symbols is to attract your attention to possible hazardous conditions. This
manual uses a series of symbols and signal words which are 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.
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,

start switch keys.
10. NEVER LEAVE WHEN MACHINE IS
RUNNING. Turn power OFF and allow all
moving parts to come to a complete stop
before leaving machine unattended.
11. DO NOT USE IN DANGEROUS
ENVIRONMENTS. DO NOT use machinery in damp, wet locations, or where any
flammable or noxious fumes may exist.
12. KEEP WORK AREA CLEAN AND WELL
LIT. Clutter and dark shadows may cause
accidents.
13. USE A GROUNDED EXTENSION
CORD RATED FOR THE MACHINE
AMPERAGE. Undersized cords overheat
and lose power. Replace extension cords
if they become damaged. DO NOT use
extension cords for 220V machinery.
16. MAKE SURE GUARDS ARE IN PLACE
AND WORK CORRECTLY BEFORE
USING MACHINERY.
17. REMOVE ADJUSTING KEYS AND
WRENCHES. Make a habit of checking for
keys and adjusting wrenches before turning machinery ON.

BEFORE USING MACHINERY. Check
for binding and alignment of parts, broken
parts, part mounting, loose bolts, and any
other conditions that may affect machine
operation. Repair or replace damaged
parts.
19. USE RECOMMENDED ACCESSORIES.
Refer to the instruction manual for recommended accessories. The use of improper
accessories may cause risk of injury.
20. DO NOT FORCE MACHINERY. Work at
the speed for which the machine or accessory was designed.
21. SECURE WORKPIECE. Use clamps or
a vise to hold the workpiece when practical. A secured workpiece protects your
hands and frees both hands to operate the
machine.
22. DO NOT OVERREACH. Keep proper footing and balance at all times.
14. ALWAYS DISCONNECT FROM POWER
SOURCE
BEFORE
SERVICING
MACHINERY. Make sure switch is in OFF
position before reconnecting.
23. MANY MACHINES WILL EJECT
THE WORKPIECE

that cause the workpiece to "kickback."
15. MAINTAIN MACHINERY WITH CARE.
Keep blades sharp and clean for best and
safest performance. Follow instructions for
lubricating and changing accessories.
24. ALLERGIC REACTIONS. Be aware that
certain metal shavings and cutting fluids
may cause an allergic reaction in people
and animals, especially when cutting fumes
can be inhaled. Make sure you know what
type of metal and cutting fluid you will be
exposed to and how to avoid contamination.

Additional Safety Instructions for Lathe/Mills
1.
AVOID CRASHES. Make sure no part of
tool, tool holder, compound or cross slide,
or carriage will come into contact with the
chuck during operation.
2.
PRE-START. Before starting the machine
be certain the workpiece has been properly
engaged in the chuck and tailstock center
(if in use) and that there is adequate clearance for full rotation.
3.
4.
5.
HOLDING TOOLS. Adjust tool holder to
provide proper support for the turning tool
you will be using. Test tool holder clearance
by rotating workpiece by hand before turning lathe ON.
SPINDLE SPEEDS. Select the spindle
speed which is appropriate for the type of
work and material. Allow the lathe/mill to
gain its full speed before beginning a cut.
FEED RATE CHANGES. Never change
feed rate or spindle speeds while the lathe
is in motion.
6.
SPINDLE DIRECTION CHANGES. Never
reverse motor direction while the lathe/mill
is in motion.
7.
STOPPING SPINDLE. DO NOT stop lathe
using your hand against the workpiece or
chuck.
8.
BE ATTENTIVE. DO NOT leave lathe/mill
running unattended for any reason.
Like all machines there is danger associated with the Model G9729. Accidents are
frequently caused by lack of familiarity or
failure to pay attention. Use this machine
with respect and caution to lessen the possibility of operator injury. If normal safety
precautions are overlooked or ignored, serious personal injury may occur.
-8-
9.
MACHINE CARE AND MAINTENANCE.
Never operate the lathe/mIll with damaged or worn parts. Maintain your lathe/mill
in proper working condition. Perform routine inspections and maintenance promptly
when called for. Put away adjustment tools
after use.
10. DISCONNECT POWER. Make sure lathe/
mill is turned OFF, disconnected from its
power source and all moving parts have
come to a complete stop before starting
any inspection, adjustment, or maintenance
procedure.
11. AVOIDING ENTANGLEMENT. Keep loose
clothing articles such as sleeves, belts or
jewelry items away from the lathe and drill
spindles.
12. CUTTING TOOLS. Always use the proper
cutting tools for the material you are turning,
make certain they are sharp and that they
are held firmly in the tool holder.
13. SAFE CHUCK HANDLING. Always place
a board or piece of plywood across the
bedway when removing or installing chucks
to avoid the possibility of a finger pinch
occurring between a loose chuck and the
edges of the bedway.
14. CLEAN-UP. DO NOT clear chips by hand.
Use a brush, and never clear chips while
the lathe is turning.
No list of safety guidelines can be complete.
Every shop environment is different. Always
consider safety first, as it applies to your
individual working conditions. Use this and
other machinery with caution and respect.
Failure to do so could result in serious personal injury, damage to equipment, or poor
work results.

The unpainted surfaces are coated with a waxy
oil to protect them from corrosion during shipment. Remove this protective coating with a solvent cleaner or citrus-based degreaser such as
Grizzly’s G7895 Degreaser. To clean thoroughly,
some parts may need to be removed. For optimum performance from your machine, make
sure you clean all moving parts or sliding
contact surfaces that are coated. Avoid chlorine-based solvents, such as acetone or brake
parts cleaner, as they may damage painted surfaces should they come in contact. Always follow
the manufacturer’s instructions when using any
type of cleaning product.
Gasoline and petroleum
products have low flash
points and could cause
an explosion or fire if
used to clean machinery.
DO NOT use gasoline or
petroleum products to
clean the machinery.
Many of the solvents
commonly used to clean
machinery can be toxic
when inhaled or ingested. Lack of ventilation
while using these solvents could cause serious personal health risks
or fire. Take precautions
from this hazard by only
using cleaning solvents
in a well ventilated area.

Site Considerations
Floor and Workbench Load
Your Model G9729 weighs 525 lbs. Most commercial or garage shop floors should be sufficient
to carry the weight. Before moving the Lathe/Mill
onto a residential floor, inspect it carefully to
determine that it will be sufficient to carry the load
of the machine, the device for moving it and its
operators. The workbench the machine rests on
should be strong and stable enough to hold the
weight of the machine and the workpiece.
Working Clearances
Consider existing and anticipated needs, size of
material to be processed through each machine,
and space for auxiliary stands, work tables or
other machinery when establishing a location for
your lathe/mill combo (see Figure 4).

Moving & Placing
Base Unit
The Model G9729 requires the use of lifting
equipment such as a fork lift, engine hoist or
boom crane. DO NOT lift the machine by hand.
Holes are provided in the edge of the lathe bed
for inserting 3⁄4" steel rods for lifting (see Figure
5). Used in conjunction with lifting straps and following safe lifting procedures as detailed by the
manufacturers of these lifting devices, the lathe/
mill can be safely lifted off the pallet and placed
on a sturdy work bench.
Practice safe lifting:
•
Position the tailstock and apron to the far
right on the lathe bed. (Opposite of the headstock.)
•
Make sure the steel rods for lifting extend at
least 8" on each side of the lathe bed.
•
DO NOT lift the machine from any other
points than the lifting holes provided.
•
Use lifting equipment such as a fork lift,
engine hoist or crane to move or lift the lathe/
mill. Never use only human power to lift the
machine.

Steady and Follow
Rest Removal
Follow Rest
Removed
The Model G9729 Lathe/Mill comes equipped
with a steady rest and follow rest. These are used
to support smaller stock while turning, drilling or
boring. They are installed at the factory for shipping purposes and should be removed at this
time. The steady rest has a single clamp bolt that
once removed, allows the clamp shoe to come
out the side (Figure 8) and the main body to be
lifted off of the lathe bed.
To remove the follow rest, simply remove the two
cap screws at its base. We recommend threading
the screws back into the mounting holes to keep
the holes clear of debris and to make sure they
do not become misplaced.

Test Run
Inspect your machine for
loose nuts and bolts, and
ensure no tools are left
in or around the machine
before connecting power.
Failure to do this may
result in personal injury.
Now that the lathe/mill is set up and you have
read the safety guidelines, it’s time to give each
motor a test run.
The purpose of the test run is to make sure the
lathe/mill is wired correctly and the motors are
working properly before proceeding with additional set up. Check to make sure that auto feeds
are not engaged, the chucks are secure in the
spindles, and there are no loose parts around
the spindles. Set the lathe/mill to the slowest
RPM before the test run. Refer to Control Panel
on Page 19, Lathe Speeds on Page 34, Mill
Speeds on Page 44, and Lubrication on Page
51 before doing the test run.
The lathe and mill motors will be tested independently. Before starting the lathe/mill:
Keep clothing rolled
up and out of the way
of machinery and keep
hair pulled back.
Disconnect power to the
machine when performing any adjustments or
maintenance. Failure to
do this may result in serious personal injury.
1.
Make sure the machine is properly grounded, the power switch is turned OFF, and
both reversing switches are set to the middle
position.
2.
Inspect the machine to ensure that all hand
tools are out of the way, guards are in place
and nothing is impeding the movement of
either chuck. Check this by rotating each by
hand.
3.
Rotate the EMERGENCY STOP button in
the direction of the arrows on the button and
allow it to pop out.
4.
Push the START button on the control panel.
While keeping your hand on the reversing
switch for the lathe, turn it to the FORWARD
position. The lathe should run smoothly with
little or no vibration or rubbing noises when it
starts. Strange or unnatural noises should be
investigated and corrected before operating
the machine further.
5.
If the lathe/mill is running correctly, turn the
reversing switch to the OFF position, wait for
the machine to come to a complete stop.­­­­
Wear safety glasses during all operations on the
lathe/mill.Failure to comply may result in serious
personal injury.

6.
Return to the first screw and tighten it a little
more. Tighten the other screws also but only
enough so the gap between the chuck and
the back plate remains even.
5.
Remove the last screw and the chuck.
Note—Support the bottom of the chuck with
a block or an assistant. It is important that
you are ready to support its weight (35-50
lbs. depending on the chuck).

G9729 Combination Lathe/Mill
Lathe Chucks with
Mounting Plate
The Model G9729 Lathe/Mill comes equipped
with a 5'' 3-jaw chuck (already installed).
The 3-jaw chuck is a scroll-type chuck, meaning
that all three jaws move simultaneously when
the chuck key is turned. Most 4-jaw chucks, on
the other hand, feature jaws that are adjusted
independently. A 4-jaw chuck can be used to hold
square or rectangular stock and is used to “dial
in” stock to true axial alignment. Rotate the chuck
key clockwise, closing the jaws (Figure 11).
Please note that an adapter plate has been provided for mounting a 4-jaw chuck. Please see
Grizzly’s current catalog for ordering information
on 4-jaw chucks.
To use this adaptor plate:
1.
Fasten the plate to the 4-jaw chuck using the
screws provided with the chuck.
2.
Fasten the plate to the spindle plate using
the three screws that were removed from the
3-jaw chuck.
DO NOT mount chucks measuring larger than 6"
in diameter on this spindle.
Some 4-jaw chucks may not readily mount to the
back plate provided. It may be necessary to drill
and tap new mounting holes and/or resurface and
shoulder the plate so the chuck can be mounted
accurately and safely. See Replacing Jaws on
Page 23.

Chuck Jaws
The 3-jaw chuck supplied with the lathe/mill
comes with 2 sets of jaws which are depicted in
Figure 12. These are commonly known as the
internal and external jaws. While both can hold a
workpiece on the inside or outside surface of the
jaw, the most common uses are shown in Figure
13.

G9729 Combination Lathe/Mill
Replacing Jaws
Changing jaws on the 3-jaw chuck is straight forward, but attention must be paid to the sequence
in which the jaws are loaded into the chuck.
Follow the instructions below.
Lead Thread
Always disconnect the power to the machine
before making adjustments, set-up changes
or cleaning. Failure to do so could result in
injury to yourself and others.
Figure 14. Arrow points to the lead of the scroll.
To replace the jaws:
1.
Unplug the lathe/mill!
2.
Remove all of the jaws on the chuck by turning the chuck key counterclockwise. Each
jaw will move until it reaches the end of the
lead thread of the scroll inside the chuck
body. The jaws can then be pulled out of the
chuck by hand.
It is important to follow these points when replacing jaws in your 3-jaw chuck:
•
The jaws must be loaded in sequence beginning with the #1 jaw.
•
The chuck, scroll, and jaws should be thoroughly cleaned before assembly. (A paint
brush works great for cleaning the scroll).
3.
Examine the inside of each slot in the chuck
for debris and clean.
•
Never use a combination of inside and outside jaws to hold a workpiece.
4.
Examine each chuck jaw. Numbers can be
found in the slot, at the bottom of each jaw.
•
5.
Locate the slot and the jaw with the #1 and
rotate the chuck key in the clockwise direction until you see the beginning of the lead
thread on the scroll come into view through
the slot, then back it off slightly until it disappears again. In Figure 14, the lead thread is
still showing in the slot. The jaw cannot be
loaded until the lead thread for the scroll is
no longer seen in the slot.
DO NOT over-tighten the chuck jaws.
Damage will occur, resulting in loss of accuracy.
•
DO NOT load the jaws into chuck incorrectly
to do eccentric work. Use a 4-jaw chuck for
this purpose.
•
3-jaw chucks will always have a little runout.
It is advisable to measure the runout of a
workpiece after it is mounted in the chuck.
If a higher degree of accuracy is desired,
replace the 3-jaw chuck with a 4-jaw chuck
and adjust the workpiece while using a dial
indicator until the desired concentricity is
achieved.
6.
Slide the #1 jaw into the slot and rotate the
key clockwise a couple of turns.
7.
Repeat Step 5 for jaw #2 and #3 in
sequence.
G9729 Combination Lathe/Mill

Face Plate
6.
Check your centerline, as tightening the
clamps may have caused it to move. Adjust
as necessary.
The face plate supplied with the model G9729
Lathe/Mill can be easily mounted to the spindle
once the chuck has been removed. Installing the
faceplate follows the same steps as any of the
lathe chucks. In Figure 15 the face plate is being
set up to hold a workpiece for precision boring.
Always use a minimum of 3 independent clamps
when holding eccentric workpieces.
7.
Use a lower RPM when machining heavy
eccentric workpieces. Take into consideration workpiece size and material.
Figure 15. Setting up face plate.
Thrown workpieces or
chuck keys can cause
serious injury or death to
the operator or bystanders. Securely clamp your
workpiece and remove
the chuck key before
turning lathe ON!
Failure to provide adequate clamping will
cause workpiece to eject causing serious
injury or death to operator or bystanders. Use a minimum of three independent
clamping devices when turning eccentric
workpieces.
To load a workpiece:
1.
Unplug the lathe/mill!
2.
Support the workpiece.
3.
Lock the tailstock and then turn the tailstock
quill so the dead center makes contact with
the centerpoint of your workpiece.
4.
Lock the tailstock and apply sufficient pressure
to hold the workpiece in place. Depending on
the workpiece, some additional support may
be needed.
5.
Secure the workpiece with a minimum of
three independent clamping devices. Failure
to follow this step may lead to deadly injury
to yourself or bystanders. Take into account
rotation and the cutting forces applied to the
workpiece when clamping to the faceplate.
Make sure your clamping application will
not fail!
-24-
G9729 Combination Lathe/Mill
Dead Center
The dead center is used to support stock that
is too long to be supported by the chuck alone.
Stock protruding more than 21⁄2 times its diameter
should be supported by a dead or live center.
Insert the end of the dead center into the tailstock
bore until it seats. The force of the dead center
contacting a mounted workpiece will fully seat the
taper when the handwheel is tightened.
When using a center, the tailstock quill should
protrude about 1⁄2'' and not more than 11⁄4'' out of
the tailstock body (Figure 16).
To minimize wear and maximize smooth operation, oil the tip of the dead center before seating
it in the workpiece as in Figure 17. Heat from friction will reduce the life expectancy of the center,
and may cause chatter in the workpiece and spoil
the center hole.
Figure 16. Dead center installed in tailstock.
D
21⁄2 x D
Always use a center to
support the end of any
workpiece that protrudes
out of the chuck further
than 21⁄2 times its own
diameter. A workpiece
not supported this way
could bend suddenly
and cause serious personal injury.
The tailstock quill and the dead center have
a Morse Taper #3. Before assembling these,
ensure that the mating surfaces are very clean.
Clean the mating surfaces so they are free of dirt
and oil. These parts will last longer and remain
accurate when properly cleaned before assembly. Morse tapers will not interlock when dirt or oil
are present on the mounting surfaces.
G9729 Combination Lathe/Mill
Figure 17. Oil center hole before seating the
dead center.
To remove the dead center, back the tailstock
quill all the way into the tailstock casting by turning the handwheel counterclockwise. The dead
center will pop out. Be sure to hold it before it
comes out, preventing the dead center from falling and causing any damage to the lathe or the
dead center.
The dead center is used with the idea of achieving
a more accurate finished product while keeping
the spindle RPM low. Failure to do this will burn
up the dead center. For a slight bit of accuracy
loss and large gain in time, the live center can be
used. The live center has bearings letting the center and the workpiece rotate together, instead of
the workpiece rotating around the dead center.
-25-
Tool Post
1
5
The Model G9729 comes supplied with a 4-way
turret tool post that is designed to accept up to
four 1⁄2" tool bits. Other devices and holders may
be installed into the tool post and arranged as in
Figure 18.
•
•
When more than one tool is secured into the
tool post, changing from one tool to another
is quickly done by loosening the lock lever
(#4) and rotating the post to the desired tool.
A spring-loaded catch is installed below the
tool post and allows motion in only one direction. The catch causes the tool post to stop at
the same rotational point for each tool placement. This feature can be useful for some
types of machining setups. Note— Securing
the tool post is not dependent upon the
catch. Thus, the tool post can be positioned
at any rotational location and properly fixed
with the lock lever. Also, removing the catch
and rotating it 180˚ will cause the tool post to
stop in the opposite direction.

5. Boring Bar
When securing a tool bit into the tool post,
always remember these rules:
• Secure the tool bit with at least two of the
bolts on the tool post.
• Make sure the top of the tool bit is at the
lathe spindle center line or just below. The
tailstock center can be used as a reference
as shown in Figure 19.
• Never extend the tool bit more than 21⁄2 times
its thickness from the edge of the tool rest.
I.e. a 3⁄8" tool bit should only extend 15⁄16" past
the bottom of the tool rest. Less is better!
Figure 19. Using a center to check tool bit
height.
• Always use sharp tool bits.
•
-26-
Avoid using tool bits that require shimming.
If you must, be sure to use steel shims as
opposed to aluminum or brass shims. Soft
shims may give, allowing the tool bit to
become loose! Soft shims will also contribute
to poor surface finishes.
G9729 Combination Lathe/Mill
Tailstock Controls
Tailstock
Figure 20 shows the locations of the tailstock
controls.
The tailstock on the Model G9729 is aligned
with the headstock at the factory. However, we
recommended that you take the time to ensure
that the tailstock is aligned to your own desired
tolerances.
1. Tailstock Handwheel
Turning the handwheel advances or retracts the
quill in the tailstock. The graduated dial on the
handwheel is adjustable.
To align the tailstock:
1. Center drill a 6'' long piece of round cold rolled
stock on both ends. Set it aside for use in
Step 4.
2. Quill Lock Lever
This lever locks the tailstock quill in place.
3. Tailstock Lock Lever
This lever locks the tailstock in place on the lathe
bed.
4. Offset Mechanism
Loosening these bolts allows the tailstock to be
offset from center by turning a screw. This feature will allow taper turning when a workpiece is
held between centers.
2. Make a dead center by turning a 60° point
on a piece of scrap material (Figure 21).
Note— As long as it remains in the chuck, the
point of your new center will be accurate to
your spindle axis. Keep in mind the point will
have to be refinished whenever it is removed
and returned to the chuck.

of the stock and check for a taper. Repeat as
necessary until the desired amount of accuracy is achieved.
NOTICE
DO NOT forget to lock down the tailstock
after each adjustment. Failure to follow this
notice may cause damage to the tailstock,
workpiece or both.
Figure 23. Adjusting for headstock end taper.
6.
Measure the workpiece with a micrometer.
If the stock is fat at the tailstock end, the
tailstock needs to be moved toward the
operator half the amount of the taper (Figure
23). If the stock is thinner at the tailstock
end, the tailstock needs to be moved away
from the operator by at least half the amount
of the taper (Figure 24).

Tailstock Drill
Mounting
Tailstock Drill
Removal
Prior to mounting the drill chuck into the tailstock,
wipe the inside of the tailstock quill and arbor
down with a clean dry cloth and inspect them
for nicks or scratches. Any irregularities on the
surface of the arbor or inside the tailstock quill
will hinder the locking capability of the taper and
should be dressed smooth with a fine file. Then
wipe down with your hand to finish the cleaning
process.
Because the drill chuck arbor is threaded on the
small end, removal requires the use of a mallet
and a wooden dowel as shown in Figure 26. Tap
along the back edge of the drill chuck on the left
and then the right. The drill chuck and arbor will
pop loose from the tailstock quill.
To mount the drill chuck into the tailstock of the
lathe, slide the arbor into the tailstock quill about
one half of the way. This should seat it well into
the tailstock quill.
Drill chuck arbors with a standard tang (or flat key)
on the small end of the taper allow the operator to
simply turn the tailstock handwheel counterclockwise until the drill chuck arbor pops loose. Grizzly
offers a variety of chucks and arbors. Please see
our current catalog for more information.

Carriage Controls
The lathe has 3 handles for manual control of the
tool bit during machining operations.
Compound Slide
This slide is adjustable so that cuts may be produced with an angle. By loosening the bolts at
the swivel base as shown in Figure 27, the compound may pivot to any angle relative to the turning axis of the lathe spindle. This feature allows
tapered cuts to be produced on a workpiece.
Apron
The longitudinal motion of the apron is controlled
by the lower handwheel (Figure 28) on the face
of the apron or the hand crank at the end of the
lathe bed. The handwheel will be used most often,
but when the hand crank is used, remember that
the half nut must be engaged and the crank must
be pushed in before it will move the apron. The
motion of this slide is used when cutting along
the length of a workpiece. This slide can also be
operated with the power feed feature.
Cross Slide Handwheel
Apron Handwheel
Figure 28. Carriage handwheels.
Graduated Dials
Figure 27. Changing the angle on the
compound slide.
Cross Slide
This handwheel moves the compound slide
across the lathe bed (see Figure 28). Turning
the dial clockwise moves the slide away from
the operator. The motion of this slide is used for
facing a workpiece and when advancing a cut
for reducing a diameter. The dial has 100 divisions with each mark representing 0.001" (one
thousandths of an inch) of motion for the slide.
The label above the dial reports that each line
represents 0.002" Ø. It is best to think of this as
the amount of reduction in diameter on the part,
per mark on the dial. Therefore, rotating the dial
10 marks will move the slide 0.010", and multiplying this amount by 0.002" equals 0.020". The
workpiece diameter will be reduced by 0.020".
-30-
Each dial can be rotated without turning the hand
crank. This is helpful because the dial can be set
to zero after the tool bit touches the part. The
graduated dial can be adjusted by holding the
hand crank with one hand and turning the dial
with the other.
G9729 Combination Lathe/Mill
Carriage Lock
The carriage lock lever is located under the right
hand side of the apron as shown in Figure 29.
This allows the carriage to be locked in place for
precision facing operations while using the lathe
or to make a set up in a milling operation more
rigid.

Follow Rest
4.
Lubricate the brass finger surfaces with oil
prior to seating them on the workpiece and
occasionally during use.
The follow rest is used on long narrow stock to
help keep deflection to a minimum. In normal use,
the cutter applies some pressure to the part. In
the case of slender parts (even those supported
by a center mounted in the tailstock) there is a
tendency for the part to deflect away from the
cutter. The follow rest keep this from happening
because the brass fingers support the workpiece
near the point of contact with the cutter. Figure
30 shows an example of follow rest use.
5.
Adjust the brass fingers until they lightly
touch the workpiece. Note—To minimize
deflection of the part during set up, use the
method shown in (Figure 31). The indicator
is set opposite to one of the brass fingers
and the brass finger is adjusted until the
needle on the dial moves, then it is backed
off to the original setting. Each brass finger
is adjusted this way.
NOTICE
The workpiece must be supported with a
center mounted in the tailstock when using
the follow rest! Damage to the tool post, follow rest, and workpiece may occur if this
notice is ignored.

3.
Secure the workpiece between centers or
into a 3- or 4-jaw chuck with a center mounted in the tailstock.
-32-
G9729 Combination Lathe/Mill
Steady Rest
3.
Loosen the thumb screws for each brass
finger and adjust the brass fingers to allow
plenty of clearance for the workpiece.
The steady rest is used for the same reasons as
the follow rest and also when support is needed
for a workpiece that cannot be supported by a
center in the tailstock. This is especially useful
when the end of a long workpiece is to be faced
(Figure 32).
4.
Loosen the knurled thumb wheel, and pivot
the head out of the way (see Figure 33).
5.
Load the workpiece into the chuck.
6.
Oil each brass finger and pivot the head back
into place and secure with the lock bolt.

Start Up and Spindle
Break-in Procedures
It is essential to closely follow the proper break-in
procedures to ensure trouble free performance.
Complete this process once you have familiarized
yourself with all instructions in this manual.
To begin the start up and break-in procedure:
1.
Check oil levels in the headstock and apron.
Follow all lubrication procedures highlighted
in Lubrication in the MAINTENANCE section on Page 51 of this manual.
2.
Make sure there are no obstructions around
or underneath the spindle.
3.
Turn the spindle ON/OFF switch to either the
FORWARD or REVERSE position and verify
the spindle rotates in the proper direction.
4.
Set the spindle speed to the lowest RPM,
refer to Lathe Speeds and Mill Speeds sections on Pages 34 & 44.
5.
Turn the lathe ON and let it run for a minimum of 10 minutes.
6.
Turn the lathe OFF, change gears to the next
highest RPM and repeat this step for each
RPM setting.
7.
Repeat these steps for the mill.
8.
Start with the slowest RPM and change Vbelts to the next highest RPM and repeat this
step for each RPM setting.
NOTICE
Feed Lever
The feed lever allows the power feeding feature
of the lathe to be turned ON and OFF. When
turned to the right, as in Figure 36, the feed
lever engages power to the leadscrew, providing
power to the apron and cross slide. When turned
to the left, the lever disengages the power feed,
enabling the apron to be fed manually with the
hand crank at the end of the lathe bed. The hand
crank cannot be turned manually unless the feed
lever is turned to the left.
Figure 36. Feed lever indicated by arrow.
The hand crank has a
clutch so that it will not
turn when the power feed
is used. DO NOT engage
the clutch by hand while
the machine is running.
Injury can occur if this
caution is ignored.
Failure to follow start up and spindle breakin procedures will likely cause rapid deterioration of spindle and other related parts.
Check all oil levels and lubrication points
before starting lathe. Excessive wear will
result if moving parts are not lubricated!

Feed Selection
NOTICE
Never move the feed rate lever while machine
is running. Damage to the machine will
occur.
NOTICE
DO NOT force any lever on this machine. If
the lever will not engage, with the machine
OFF, rotate the chuck by hand while keeping light pressure on the selector. As the
chuck rotates it aligns the gear teeth inside
the selector box and as the gears come to
engage the selector will engage.
Figure 37. Feed rate selection lever.
The Feed Rate selection Lever, shown in Figure
37, controls internal gears that change the feed
rate. The coarsest setting for the feed rate lever
is in the “I” position. When the lever is turned to
the “II” position, the feed rate is reduced by one
half of the feed rate of position “I”. When this
lever is turned to the “III” position, the feed rate
is reduced by one half the feed rate of position
“II”. In position “I”, roughing would most likely be
done and in the “III” position, finishing would most
likely be done.

Half Nut
Apron Power Feed
The half nut lever is located under the left hand
side apron (Figure 40). This handle may be
engaged and disengaged while the machine is
running and while making a cut. Move the lever
to the down position to engage the half nut.
Because the threads of the nut and leadscrew
will not always be aligned, engaging the half
nut may require waiting until they align, with the
machine running. Lift the handle in the direction
of the arrow as shown in Figure 40. DO NOT
force the handle, apply light pressure to the handle and when the threads are aligned the handle
will engage.
The apron power feed is designed to make work
more efficient, provide better surface finishes and
aid in cutting threads.
•
Once the proper gears have been installed,
(see Changing Gears on Page 39) and the
feed rate selected, power to the apron and
cross slide is provided by the leadscrew,
shown in Figure 41.
•
In the case of the apron, motion starts by
engaging the half nut lever, shown in Figure
40.
•
In the case of the cross slide, a ring is pulled
out, as shown in Figure 41.

Head Rotation
Fine Down Feed
The head of the Model G9729 can be rotated 90°
in both directions.
The up and down motion of the mill spindle is
controlled just like a drill press. But unlike most
drill presses, the Model G9729 is supplied with
a fine feed handle, indicated by the arrow in
Figure 58.
To rotate the head:
1.
Unplug the lathe/mill!
2.
Loosen the head lock handles shown in
Figure 56.
3.
Rotate the head to the desired position.
4.
Tighten the head lock handles.
Quill Lock Lever
To activate this feature, rotate the quill lever
while pressing the black knob in the center of
the hub (Figure 58). The knob will engage and
the spindle will no longer move using the quill
lever. Rotating the fine feed handle in a clockwise direction will cause the spindle to go down.
To disengage this feature, rotate the fine feed
handle and pull on the knob in the center of the
hub. Rotating the crank handle will always aid in
engaging or disengaging this feature.
Fine Feed Handle
The height of the spindle can be locked with the
quill lock lever. Set the desired height of the spindle, and lock the spindle in place (Figure 57).

Machine Vise
The Model G9729 comes supplied with a milling vise that also serves as the compound for
the lathe. The 4-way tool post must be removed
before using the vise.
The milling vise can be aligned to the axis of the
lathe or at any angle desired. Care must be given
to setting the vise if a precision angle is needed.
The following instructions are given to make the
jaws parallel to the travel of the cross slide.
5.
When the vise has moved so the indicator tip
is at the other end of the parallel, pivot the
vise one half the amount of motion detected
in Step 4.
6.
Move the vise to the starting position and
note the difference. Again, pivot the vise one
half the difference.
7.
Repeat Steps 4–6 until the dial remains stationary when the vise is moved.
8.
Tighten the pivot bolts on the base of the
vise and re-indicate to make sure that nothing has moved.
Never use a vise for
milling unless it is rated
for milling machines.
Drill press or bench
vises are not designed
for the rigors of machining. Vise failure during
a milling operation may
lead to serious personal
injury.
To make the jaws parallel to the cross slide
travel:
1.
Loosen and remove the lock handle and
slide the tool post off of the compound/vise.
2.
Loosen the swivel bolts on the compound/
vise so it can swivel, but not too freely.
Slight resistance will help keep the vise from
changing positions unexpectedly, and keep
grit from getting between the two surfaces.
Pivot the compound/vise so the jaws of
the vise are roughly aligned with the cross
slide.
3.
Place a dial indicator mounted to a magnetic base on the lathe bed using a parallel
clamped in the vise jaws (Figure 59).
4.
Move the cross slide with the handwheel
and watch the dial. Note the direction the
needle is moving on the dial and by how
much.

Drill Chuck Removal
Drill Chuck Mounting
The drill chuck and arbor come installed on the
drill press/milling spindle from the factory. When
the time comes to remove and reinstall it, use
these instructions:
1.
Unplug the lathe/mill!
2.
Remove the small plastic cap on top of the
belt guard and slide the draw bar out of the
spindle through the top.
3.
Clean the spindle taper and the arbor taper
thoroughly, then wipe with your hand until its
clean.
4.
Insert the arbor half way into the drill press
spindle, then quickly slide it in place to seat
the two tapers together.
5.
Replace the draw bar and thread it into the
arbor. DO NOT over tighten! The draw bar
only needs to be lightly tightened. Tightening
any further will make it difficult to remove the
arbor! Again the taper is what holds the two
pieces together, the draw bar just keeps
them from chattering loose.
To remove the drill chuck from the drill press/
milling spindle:
Always disconnect the power to the machine
before making adjustments, set-up changes
or cleaning. Failure to do so could result in
injury to yourself and others.
1.
Unplug the lathe/mill!
2.
Return the spindle to the highest position.
3.
Remove the small plastic cap on top of the
belt guard and unscrew the draw bar 3 turns.
Note—The draw bar screws into the arbor
and keeps the arbor from chattering loose
when machining or drilling. Three turns on
the draw bar is all that you need, any more
and the threads on the draw bar and the
arbor will be damaged when hitting the end
of the draw bar with the hammer. Any less
and the arbor does not have enough room
to pop loose from the inside taper of the
spindle and the outside taper of the arbor.
4.
Secure the quill with the quill lock.
5.
Holding onto the outside of the drill chuck
with your free hand (never hold onto anything from the bottom, when removing it
from the spindle), tap the end of the draw
bar with a soft faced mallet. DO NOT use a
steel hammer! Damage to the draw bar and
hammer, such as chipping, may occur.
6.
Once the arbor is loose, hold the drill chuck
with one hand and unthread the arbor with
the other.

SECTION 7: MAINTENANCE
Cleaning
Always disconnect power
to the machine before
performing maintenance.
Failure to do this may
result in serious personal injury.
Schedule
For optimum performance from your machine,
follow this maintenance schedule and refer to any
specific instructions given in this section.
Daily Check:
•
Loose mounting bolts.
•
Damaged tool bits and end mills.
•
Worn or damaged wires.
•
Any other unsafe condition.
•
Lubrication.
Monthly Check:
•
V-belt tension, damage, or wear.
•
Clean/vacuum dust buildup from inside cabinet and off motor.
-50-
Make sure to unplug the lathe/mill before cleaning it. Clean your machine every day or more
often as needed. Remove chips as they accumulate. Chips left on the machine soaked with water
based coolant will eventually invite oxidation
and gummy residue to build up around moving
parts. Cleaning will help keep your lathe running
smoothly. Always be safe and responsible with
the use and disposal of cleaning products.
Unpainted Cast Iron
Protect the unpainted cast iron surfaces on the
table by wiping the table clean after every use.
Keep tables rust-free with regular applications of
products like, G96® Gun Treatment, SLIPIT®, or
Boeshield ® T-9 (see ACCESSORIES section on
Page 48 for more details).
G9729 Combination Lathe/Mill
Lubrication
Your Model G9729 will function best when it is
clean and well lubricated. Take the time to wipe
down and oil the machine before each use. We
recommend using ISO 68 or SAE 20W nondetergent oil unless otherwise specified. Ball fittings will require the use of an oil gun. Press the
ball with the tip of the gun and squirt a little oil
under pressure. Wipe the ball fitting before and
after each use to prevent contamination.
External Gearing: Apply only a minimal amount
of oil to the teeth of the end gears after assembly
or each day. Note—Avoid getting oil on the belt
or pulleys when lubricating.
Remove the gear in Figure 69, and apply a few
drops of oil to the bushing once a day.
Apron and Cross Slide: Apply lubrication directly to the dovetail ways of the apron and cross
slide.
Figure 69. Oil external gears and bushing.
Bearings: Lubrication for the internal gears
occurs as the machine runs and oil circulates
from the gear box. However, the bearings should
be lubricated through the ball fittings indicated
by the arrows in Figure 70. Apply oil every 3
hours of actual use and just before starting the
machine each day.
Figure 68. Oil ports indicated by arrows.
Compound: This slide is supplied with ball fittings on its top surface and should be oiled at the
same time as the apron (Figure 68).
Figure 70. Bearing lubrication points.
G9729 Combination Lathe/Mill
-51-
Motor: The bearings used in the motor are
shielded and lubricated for life, therefore, no
lubrication is necessary.
Leadscrew: Be sure to clean and lubricate the
leadscrew. There is also a bearing on the tail
stock end that will require oil.
Headstock Gearbox: The oil in the headstock
should be changed after the first 2 hours of use,
then every 6 months, depending on usage. We
recommend using a light weight, non-detergent oil. Viscosity can range from 10W to 30W
and may include multi-viscosity oil in this same
range.
To remove the oil in the gear box, remove the
change gear directly under the spindle, remove
the cap screw indicated in Figure 71, and place
a can under the drain hole to collect the waste
oil.
Figure 72. Gear box fill hole.
Tailstock: The tailstock is fitted with 2 oiling
ports. The tailstock quill may be oiled directly.
Apply oil each week or after every five uses
(depending on the frequency of operation). Be
sure to clean the slide ways for the tailstock
and lift the tailstock and squirt a few drops of
oil on the ways. It is a good idea to remove the
tailstock, once a month and wipe the bottom thoroughly and replace (Figure 73).

SECTION 8: SERVICE
Gibs
Always
disconnect
power to the machine
before performing service adjustments. Failure
to do this may result in
serious personal injury.
About Service
There are three gib adjustments for the Model
G9729— the cross-slide gib, the compound slide
gib and the apron gib.
Cross-slide Gib: The gib on the cross-slide is
adjusted by tightening or loosening the 2 wing
bolts located on the right hand side of the slide
(see Figure 74). These will also serve as table
locks.
This section is designed to help the operator with
adjustments that were made at the factory and
that might also need to be made during the life of
the machine.
This section is provided for your convenience—
it is not a substitute for the Grizzly Service
Department. If any adjustments arise that are not
described in this manual, then feel free to call the
Grizzly Service Department at (570) 546-9663.
Similarly, if you are unsure of how to perform
any procedure in this section, the Grizzly Service
Department will be happy to guide you through
the procedures or help in any other way.
Figure 74. Gib adjustment wing bolts.
Continued on next page
G9729 Combination Lathe/Mill
-53-
Compound Gib: The gib on the compound
has two set screws to maintain tension on the
slide (see Figure 75). To adjust these to the
proper tension, loosen the cap screw positioned
between them and turn the hand crank while
adjusting each screw. Tighten until extra effort
is required to move the slide then back off the
set screw a little. When needed, the slide can be
locked in place using the cap screw.
NOTICE
When adjusting gibs, keep in mind that
the goal of gib adjustment is to remove
unnecessary movement from the slides
movement without causing them to bind.
Loose gibs may cause poor finishes on the
workpiece and undue wear on the slide, nut
and lead screw. Over tightening will make
turning the handwheel difficult.
Figure 75. Gib adjustment set screws.
Apron Gib: There are 2 set screws that tension
the saddle gib (see Figure 76). Before making
adjustments to the saddle gib, ensure that the
front lock lever is loose by turning it counterclockwise. It is important that the set screws are tightened evenly. A slight drag should be detected
while turning the hand crank on the apron.
