NOVA Titan III Chuck Features:
Thank you for purchasing Teknatool Nova Titan 5inch Chuck. We are
confident that it will help in both enhancing as well as advancing your
woodturning. The Teknatool Nova Titan 5inch Chuck is a very versatile
unit, designed to offer a wide range of work holding modes. The Nova
Titan 5inch Chuck has a powerful grip while being quick and easy to
use.
It combines the best features of our Nova series chucks and similar
woodturning chucks (wide jaw movement, quick two way grip) with the
advantages of superior gripping power and a convenient one handed
operation. The Nova Titan also has some special safety features: a
travel stop on the jaws and a contracting scroll jaw action to centre
under power with no work mounted. This means that there is very little
chance of the jaws flying out of the chuck - a common hazard with
many chucks.
The Nova Titan, utilizing the two screw position, can take the existing
NOVA accessory jaws. This provides maximum interchange ability of
jaws between all NOVA chucks.
The Titan using the wide variety of accessory jaws can be used to
expand into recesses or contract around round/square wood spigots of
varying sizes and applications. The chuck can swap from the
expansion/dovetail mode to the spigot mode and back instantly, with
no adjustments or extra fittings being necessary. In either modes, any
spigot or recess size can be selected between the minimum and
maximum range of the jaws. With the add-on accessory jaws removed,
the jaw slides can be used to grip smaller spigots. The chuck also
utilises a powerful Woodworm screw for screw chuck work. (Included
with standard model only)
The Jaw accessories are included at the back of this manual. However
the range is steadily being expanded to include more options. Check
with your reseller or at www.teknatool.com for the latest accessories.
As a valued customer, we would be pleased to hear from you and how
you found your Nova Titan. Any comments on the chuck or accessory
ideas would be very welcome so that we can continue to offer what we
believe is the best woodturning chucking system available.

9. GROUND ALL TOOLS. If the tool is equipped with a three-prong
plug, it should be plugged into a three hole electrical receptacle. If an
adapter is used to accommodate a two-prong receptacle, the
adapter plug must be attached to a known ground. NEVER remove
the third or grounding prong.
10. DISCONNECT TOOLS. Ensure the plug is removed from the wall
socket before servicing and when changing accessories such as
blades, bits, cutters and fuses, etc.
11. AVOID ACCIDENTAL STARTING. Make sure switch is in the Off
position before plugging in power cord into the wall socket.

105-0717-006 6
12. NEVER LEAVE MACHINE RUNNING UNATTENDED. Do not
leave machine unless it is turned off and has come to a complete
stop.
13. KEEP GUARDS IN PLACE. Ensure guards are in working order.
14. USE CORRECT TOOLS. Do not use a tool or attachment to do a job
for which it was not designed.
15. DON’T FORCE THE TOOL. It will do the job better and be safer at the
rate/force for which it was designed.
16. MAINTAIN TOOLS IN TOP CONDITION. Keep tools sharp and clean
for the best and safest performance. Follow instructions for lubricating
and changing accessories.
17. NEVER STAND ON THE TOOL. Serious injury could occur if the tool
is tipped or if the cutting tool is accidentally contacted.
18. REMOVE ADJUSTING KEYS AND WRENCHES. Form a habit of
checking to see that keys and adjusting wrenches are removed from
tool before turning it on.
19. DON’T OVERREACH. Keep proper footing and balance at all times.
20. DIRECTION OF FEED. Feed work into the blade or cutter against the
direction of rotation.
21. ATTENTION TO WORK. Concentrate on your work. If you become
tired or frustrated, leave it for awhile and rest.
22. SECURE WORK. Use clamps or a vice to hold work when practical.
It’s safer than using your hand and frees both hands to operate tool.
23. CHECK DAMAGED PARTS. Before further use of the tool, any part
that is damaged should be carefully checked to ensure that it will
operate properly and perform its intended function. Check for
alignment of moving parts, binding of moving parts, mounting, and any
other conditions that may affect its operation. Any damaged part
should be properly repaired or replaced.
24. DRUGS, ALCOHOL OR MEDICATION. Do not operate machine while
under the influence of drugs, alcohol, or any medication.
25. DUST WARNING. The dust generated by certain woods and wood
products can be harmful to your health. Always use an approved dust
mask and operate machinery in well-ventilated areas. In addition,
provide a means for proper dust removal. Use wood dust collection
systems whenever possible.

105-0717-006 7
ADDITIONAL SAFETY RULES:
!
Warning! Failure to follow these rules may result in serious personal
injury.
1. SEEK INSTRUCTION. If you are not thoroughly familiar with the
operation of wood lathes, obtain advice from your supervisor, instructor,
or other qualified person. Instruction from a qualified person is strongly
recommended.
2. MAKE SURE WOOD is securely clamped in the chuck before turning it on
3. EXAMINE WORK PIECE and glue joints before turning to make sure it
has no defects that would cause it to break when turning.
4. CHECK SET-UP with power Off. Examine the set-up carefully and rotate
the work piece by hand to check clearance before turning on power.
5. ADJUST TOOL REST close to the work piece. Before turning, revolve
the stock by hand to make sure it clears the rest. At intervals, stop the
lathe and readjust the tool rest.
6. DO NOT MAKE ADJUSTMENTS when the lathe or work piece is turning.
Make all adjustments with power Off.
7. TIGHTEN ALL CLAMP HANDLES on the headstock, tailstock, and tool
rest before operating lathe.
8. USE LOWEST SPEED when turning a new or unbalanced work piece.
9. USE CORRECT SPEED for turning the wood blank as wood speed will
vary depending on diameter.
10. KEEP TOOL ON TOOL REST. Tools should remain on the tool rest
whenever the tool is engaged in contact with the work piece.
11. DO NOT ROTATE CHUCK under power without wood being gripped and
securely tightened in the chuck
12. USE CORRECT LATHE TOOLS. Do not use spindle turning chisels for
faceplate mounted work, and vice versa. Spindle turning tools used for
faceplate turning may grab the work piece and pull the chisel from your
control.
13. DO NOT POUND WORK PIECE into headstock drive (spur) center while
attached to the lathe when turning between centers. Pound the drive
center into the work piece with a soft mallet before installing it between
centers in the lathe.
14. DO NOT USE TAILSTOCK to drive work piece into the drive (spur) center
when turning between centers. Secure work between centers with light
pressure from the tailstock quill action.
15. FASTEN STOCK SECURELY BETWEEN CENTERS. Make sure the
tailstock is locked before turning on the power.
16. NEVER LOOSEN TAILSTOCK spindle or tailstock while work piece is
turning.

105-0717-006 9
Mounting the Titan III Chuck on a Lathe
CORRECT MOUNTING OF CHUCK TO LATHE SPINDLE IS VERY
IMPORTANT TO ACHIEVE ACCURACY.
WE STRONGLY RECOMMEND THAT THE CHUCK IS NOT USED
ON LATHE SPINDLES UNDER 1in (25mm) diameter.
FITTING CHUCK TO LATHE
Correct fitting of chuck to lathe spindle is important to ensure accuracy.
The chuck body must contact an accurate shoulder on the lathe
spindle or bearings to ensure chuck will run true.
There can be a wide variety of lathe spindle thread and spigot
dimensions even within the same thread size. The internal thread size
is kept to standard tolerances.
CHECK THE FOLLOWING:
Although the Chuck may screw on part way it may not contact
properly with spindle spigot - a spacer may be necessary. This
would be the responsibility of the chuck user. Make sure the chuck is
screwed to lathe thread properly - a good check is to see whether it
screws home on the spindle same as any another lathe fixture such as
a faceplate. POOR FIT OF CHUCK TO LATHE SPINDLE CREATES
A SERIOUS HAZARD WHERE CHUCK COULD DISLODGE FROM
LATHE. DO NOT ATTEMPT TO USE CHUCK UNLESS THE CHUCK
IS CORRECTLY FITTED TO LATHE SPINDLE.

105-0717-006 10
Using the Titan III Chuck
Mounting Add-On Jaws
MOUNTING ADD-ON JAWS
Your standard Nova Titan
5in chuck is provided with
PowerGrip add-on jaws.
They need to be located and
screwed on to the jaw slides
of the chuck. The same
procedure outlined below
must be followed for all
accessory jaws as well. IT IS
IMPORTANT TO LOCATE
JAWS PROPERLY IN THE
JAW SLIDES FOR THE
CHUCK TO FUNCTION
ACCURATELY.
Follow the method set out below
1. You will notice that the back of the jaws have a stepped location
ring. This location ring is designed to fit into the grooved section of
the jaw slide for precision location. Ensure that the slide and collet
back are clean and free from any burrs or damage that might affect
location. Place the jaw segment over the hole positions on the jaw.
Press the jaw segment firmly onto the jaw slide. For the first few
times you may need to GENTLY tap the jaws into the locator slot
with a block of wood.
2. The screws can now be screwed in, using the 4mm Allen Key
provided. Lightly grease or oil screws under each head and on the
threads before use to prevent the screws from seizing in the jaw.
Preferably use an anti-seize compound e.g. ROCOL J 166 Anti-
Seize Compound. Do all screws up finger tight and then back them
off one quarter to half a turn.

105-0717-006 11
3. Wind the mounted jaws into the centre of the chuck until they all
butt against the other. Now finally tighten screws, starting with
centre screws and then outside screws. Nip screws up firmly but
DO NOT OVER TIGHTEN.
4. Check there is no light between jaw slides and add on jaw
segments or that one or more segments is not higher or lower
than the rest. If this is the case repeat procedure above.
OPERATING MODES
SCREW CHUCK: This is a convenient mounting method. The
PowerGrip Woodworm screw is purpose-designed for screw chucking.
It is a cylindrical screw which maintains its full holding power along the
whole length, unlike normal tapered screws. The thin thread form is
specially designed to cause minimum damage to wood fibres. They
grip better than screws with thicker threads because there is a larger
volume of undamaged wood retained within the screw.The woodworm
screw is made complete with the boss section in one piece. The
woodworm screw is designed to be used with the powergrip jaws
remaining in place on the chuck. This facility is very convenient for
remounting work directly onto the jaws after the screw is removed. To
convert to this operation, place the boss section into the centre of the
chuck making sure flat shanks are aligned to the jaw slides and close
jaws around it. BEFORE FINAL TIGHTENING MAKE SURE THAT
THE FRONT OF THE BOSS SECTION OF THE SCREW IS SEATED
BEHIND AND AGAINST THE POWERGRIP JAWS. This will prevent
any tendency for the boss section to creep forward when the screw is
being used. The front face of the PowerGrip Jaws has been machined
to provide an accurate backing surface. This is quite an advantage,
providing a much tighter fit and better tolerance for irregular face stock.
This feature is also quite an advantage when using the screw to mount
a bowl for first stage bowl turning - forming the outside of the bowl
straight onto the jaws (the screw is first removed) after the recess has
been formed.

105-0717-006 12
SCREW DEPTH: The screw provides 19mm (3/4 inch) of thread
beyond the PowerGrip jaws. With all wood blocks over 150mm (6
inches) in diameter the full thread depth of 19mm should be used.
Irregular, rough tree blanks (e.g. small sections of tree limbs) not
exceeding the above sizes can be held quite firmly BUT caution must
be exercised. Check for adequate contact.
CAPACITY: DO NOT USE THE SCREW FOR VERY LARGE WOOD
BLANKS. Its use is intended for small bowl and screw chucking work.
The maximum capacity which should be mounted on the screw -
250mm (10 inches) diameter x 100mm (4 inches). DO NOT EXCEED
600 RPM FOR THIS OPERATION. Use tailstock support.
PREPARATION: The 10.5mm thread requires a drilled hole about
8mm (5/16”) in diameter. The screw has considerable holding power
and it is sometimes difficult to unscrew, so wax or oil the thread before
mounting the wood. CARE: The threads are fine and can be damaged
by mishandling. DON’T hammer into wood! DO screw into a pre-
drilled hole. Any nicks on the threads can be removed by carefully
filing.
EXPANDING DOVETAIL OPERATION
Expansion of the jaws into a recess. This function is for bowl and
platter turning where the projection (depth) of the wood blank is not too
great i.e. up to 150mm (6 inches). Characteristically these items have
a parallel wood grain. IT MUST NOT BE USED FOR ANY LONG
WORK (OVER 150MM) AS THERE WOULD BE GREAT DANGER OF
WOOD TEARING OUT AND DISLODGING FROM CHUCK.
Instructions below apply to the Powergrip jaws but the general
technique is the same with other accessory jaws. However, the
maximum size of wood blank that can be mounted, the maximum
turning speed and recess size varies with the different accessory jaws.
Consult specific instructions included for each jaw set.
This strong holding method, using the power grip jaws, bowls up to
400mm (16 inches) in diameter can be turned. DO NOT EXCEED
700RPM WITH THIS OPERATION. OUT OF BALANCE STOCK
MUST BE TURNED AT THE SLOWEST SPEED POSSIBLE.

105-0717-006 13
PowerGrip jaws: Any recess can be turned between 96mm (3.8”) and
120mm (4.7”) diameter. EUROPE/UK: Maximum recess size is 8mm
(0.30"). Choose the diameter that suits your bowl design. However, the
optimum turning recess diameter (on the outside) is 99mm (3 57/64”).
As the recess diameter is increased above 99mm, less jaw contact is
made. This needs to be kept in mind when considering the recess
depth and size of wood blank being mounted. Increase the recess
depth to maximum if a recess diameter in excess of 99mm is used.
The dovetail angle is 15 degrees.
Forming a Recess
The jaw dovetail has been designed for use with a standard skew
scraper. This chisel will make a recess to the angle required. FOR
SAFETY REASONS WE STRONGLY ADVISE AGAINST USING ANY
OTHER TOOL. A profile of this chisel is shown below. It is best to
work with a tool, which is already ground, to the correct angle. All that
is necessary then is to keep the leading edge of the chisel flat on the
wood, moving forward and out to form the recess to the required
diameter and depth.
Mount bowl blank on screw as described in previous section. It may
be convenient to first mark out with a pencil, a circle on the bowl blank.
To mark out the recess diameter with pencil, hold pencil point to
desired radius, supported on the tool rest. Then revolve blank by hand
thus creating a pencilled circle. However, as specified above, any
recess diameter can be made between 96mm (3.8”) 120mm (4.7”) so
exact sizing of the recess is unnecessary.
Before scraping out the recess, slightly hollow out the centre of the
bowl blank with a bowl gouge or round nose scraper. The purpose is

105-0717-006 14
to relieve the centre so that when the recess is scraped out only half
the chisel edge needs to be used. We recommend this to reduce
tearing of the wood by scraping action; and to make the recess a little
more finished to give a better effect to the overall bowl. Extra
embellishments can also be made to the recess to enhance the bowl.
After the recess is finished and the outside of the bowl is turned to
shape, wind bowl back off screw. Bowl blank is now ready to be
reversed into the jaws. Expand the jaws into the recess. When the
jaws are expanded out into the recess, screw the wood blank gently
back and forth to make sure it is seated properly on the bottom face of
the jaws. WARNING: MAKE SURE THE JAWS ARE SEATED
PROPERLY IN THE RECESS AND THAT THE BOWL IS NOT
INCORRECTLY RIDING ON THE FLAT SHOULDER SECTION OF
THE JAWS BEHIND THE DOVETAIL. THIS COULD LEAD TO THE
BOWL DISLODGING FROM CHUCK. LOOSEN JAWS AND
REMOUNT CORRECTLY.
Now give a few gentle raps with the end of a chisel handle or wooden
mallet around centre of bowl. Use pinion handle to give an extra nip
up. Refer to chuck operation Page 4. Refer again to safety before
operation.
SPIGOT OPERATION
This is where the jaws contract around a wooden spigot for grip. This
function is mainly for box, goblet and vase turning, that is, end grain
items with a fair degree of overhang. This situation is one of the most
difficult to provide secure holding no matter what fixing method is used.
EXTREME CAUTION WITH THIS OPERATION MUST BE
EXERCISED. DO NOT EXCEED 700 RPM FOR THIS OPERATION. If
used properly the Nova Titan Chuck however, provides a very powerful
and secure grip in this mode. Instructions below apply to the Power
grip jaws but the general spigot technique is the same for other jaw
types. However, maximum turning speed and recess size varies with
different jaw types. Consult accessory jaw manual or instruction
sheets. With the power grip jaws a maximum size wood blank of
200mm (8 inches) diameter (NOT spigot size) by 310mm (12 inches)
length can be turned. Square timber of same length and between
60mm (2 23/64 inches) to 80mm (3 9/64inches) and grip of all four

105-0717-006 15
jaws into wood. MAKE SURE YOU HAVE AN ADEQUATE GRIP
BEFORE OPERATION by vigorously wrenching the limb mounted on
chuck. If any loosening occurs DO NOT PROCEED with operation.
Repeat tightening procedure and re-test grip.
SPIGOT SIZE:
PowerGrip jaws will grip a round spigot between 107mm (4.28 inches)
to 126mm (4.96 inches) approx. Square timber between 90mm (3.5
inches) to 110mm(4.33 inches) square approx. (Note: EUROPE/UK:
Maximum size is 6mm (1/4") less). Jaw slides only: With the add-on
jaws removed, the jaw slides will grip either round or square timber
down to 8mm (5/16inch). Length limits same for spigot work. Small
work not greater than this diameter can be turned at a speed NOT
EXCEEDING 1800 RPM. Larger work held in the jaw slides should not
exceed 700 RPM.
FORMING SPIGOT:
When selecting wood make sure it is sound without splits or weakness
- especially around the area where the spigot is to be formed.
REMEMBER WITH FREE END TURNING, THIS IS THE ONLY AREA
GRIP. IF ANY WEAKNESS IS FOUND, DO NOT PROCEED. Mount
wood between centres and turn the spigot area. Make the spigot as
parallel as possible to maximise the efficiency of the clamping action.
Only approximate sizing of the spigot is necessary, as the jaws will
accommodate a wide range of spigot diameters within the spigot limits
stated above.
FREE END TURNING
Turning where the work is not supported by the tailstock.
Check for adequate contact and grip of all four jaws into the wood
when using this operation. MAKE SURE YOU HAVE AN ADEQUATE
GRIP BEFORE OPERATION by vigorously wrenching the work piece
mounted in the chuck. If any loosening occurs DO NOT PROCEED
with this operation. Repeat tightening procedure and retest grip.

Maintaining the Titan III Chuck
General Maintenance
CLEANING CHUCK: The Nova Titan Chuck is perfectly enclosed from
behind which makes the gearing mechanism maintenance free over a
long period of time. However, the chuck needs to be inspected
periodically for build up of wood dust in the jaw slide area on the front
side. Wood dust build up can make the jaws difficult to move. To clean
out the wood dust build up, the following method can be used. Remove
Jaw Slides. (First removing stop screw as explained in previous
section) then using a piece of wood (matchstick size) insert in the
bottom of scroll and rotate scroll ring. This will scrape out the
accumulated wood dust.
To disassemble chuck: Over a long period of usage there could be
some accumulation of very fine dust in the gearing area behind which
may require dismantling of chuck for a full clean. Following are steps
(Refer to exploded chuck diagram, Page 5) Using expanding pliers
remove the circlip securing the backing plate. This should give enough
access to clean the gears without further dismantling of the chuck. If
you want to dismantle further, follow these instructions. Remove the
two M6 fastening screws. Next hold the chuck with the jaw slide
surface facing up. Wiggle the pinions with the help of 8mm Hexagon
Wrench till the two dowel pins have fallen down. Next remove the
pinions. Remove the second circlip securing the scroll ring. The scroll
ring can be removed now. After you have cleaned the chuck assemble
the chuck back in the same order. Re-insert the jaw slides. Remember,
after you have re-assembled the gears, apply any general grease all
around the gear area!!
Remember to replace jaw travel stop screw!!

105-0717-006 17
Stop on JAW Travel
Stop screw is located at the end of the number 2 slideway, and number
4. The screw prevents jaw slides being unwound from the chuck. Do
not exert pressure against the screw with pinion action. If screw is
removed for disassembly it must be replaced before use. Refer
exploded view diagram on page 5 of the manual, and to drawing
accompanying insertion of jaw slides below.
Caution: Do not close jaw slides to a diameter less than 8mm (5/16”)
for work holding. Do not close jaw slides to fully closed position
because jaw slides could over travel on scroll and become
disengaged.
Insertion of jaw slides
Jaw slides are numbered 1 - 4 (numbering on end of slide). (Note:
Travel stop screws need to be removed. Refer to previous jaw slide
travel lock section). When the jaws are removed from the body they
need to be reset in sequence. To reset jaws in chuck body, rotate with
pinion gear until the lead of the scroll (like a thin wedge) appears in the
opening of the slide way # 2.
CAUTION: IT IS IMPORTANT TO ROTATE THE LEADING EDGE OF
THE SCROLL BACK SLIGHTLY TO CLEAR THE SLIDEWAY
BEFORE SLIDE CAN BE INSERTED. FAILURE TO ROTATE THE
SCROLL BACK COULD RESULT IN DAMAGE TO SCROLL.
Now insert No.2 slide into slideway and rotate scroll in a clockwise
direction (chuck facing you) until the lead of the scroll appears at the
next slideway. Now engage No.3 scroll in the same manner as No.2.
Proceed in the same way in a clock-wise sequence with No.4 and No.1
slides. Refer to the diagram.

105-0717-006 18
Troubleshooting Guide
Problem
Possible Cause and Solution
1. Chuck jams
when partially
threaded onto
spindle.
Check chuck body threads are free from damage.
Check spindle has engaged with chuck body
thread correctly. See 'Fitting to Chuck' Page 7.
Make sure the grub screw has not been
SCREWED IN.
2. Chuck body
appears not to
be true
Check insert is properly home in chuck body.
Check that the insert is correctly screwed onto
lathe spindle. Insert must back against accurate
face/register or bearing on lathe spindle. See Page
7.
3. Add on jaws
do not run true
Check jaws are mounted correctly on jaw slides.
For method see Page 9. For accuracy parameters
see Page 2. When the jaws are expanded beyond
a 50mm circle they will appear to be running out
but in fact are maintaining concentricity. Always
evaluate runout from turned wood clamped in jaws
4. Jaw Slides
closed to centre
and No. 1 slide
stays in centre
when jaws are
expanded again
Jaw Slide(s) have over travelled from scroll. It will
be necessary to tap back No 1 jaw slide until it has
re-engaged. See page 8 for 'insertion of jaw slide'.
5. Chuck very
stiff to operate or
jammed
Wood dust and shavings can clog the chuck in use.
The chuck should be cleaned. Follow instruction
Page 7
6. Jaw Slides
when Wound to
centre do not
meet
Slides have not engaged sequentially in clockwise
order with scroll - 1-2-3-4. Jaw Slides could have
been inserted out of order. Check insertion
procedure Page 8.
7. When chuck is
being removed
from spindle the
body unwinds
from insert
Either lock insert in body using grub screw and
fibre washer provided or use spanner on the insert
to wind chuck off lathe.

105-0717-006 19
8. Chuck jams on
lathe spindle
This is a common problem with fixtures on a lathe.
Use piece of wood & knock against base of pinion
gear in anticlockwise direction to jar loose from
spindle. To help prevent it try a plastic or fibre
washer between insert/chuck and spigot shoulder
of a spindle. Use of washer could affect accuracy.
9. Woodworm
screw creeps
forward or is not
seated properly
in chuck
Make sure woodworm screw boss is placed
correctly between jaw slides and behind jaws. See
Page 9
10. Wooden
spigot shifts
during turning
Check that the spigot area is made correctly for
jaws to grip. Check that the spigot is not oversize.
