DANGER: THIS CHUCK IS CAPABLE OF CONTRIBUTING TO SERIOUS INJURY,AS WITH
ANY OTHER POWERTOOL ACCESSORY, IF USED IMPROPERLY ON THE LATHE.
Before using the Nova G3, read and understand this instruction manual and the lathe
owner’s manual. If you do not have a manual, contact the supplier of your lathe to obtain
one before using the lathe and Chuck.
User must be professionally trained to use this chuck. Vocational school courses
recommended. As with other chucking methods, an extremely cautious and sensible
approach is necessary. With the Nova G3 Chuck it is not possible to give exact directions as
to the amount of tightening pressure required for workholding. Follow closely strict
guidelines in this manual for different jaw types on wood blank diameters and length, plus
turning speed.

NOVAG3 CHUCK
INSTRUCTIONMANUAL FITTING CHUCK TO LATHE
Check that the chuck thread specification matches the lathe spindle thread you
have. This is important for accuracy. The chuck body must contact an accurate
register on lathe, either a shoulder on spindle or bearing face etc to ensure chuck
willrun true.If further modifications are needed (e.g. spacer)these arethe
responsibility of the user.Agood check is to see whether it screws home the same
as a faceplate or similar spindle fitting.
DONOTUSE UNLESSCHUCK ISPROPERLYFITTEDTOSPINDLE.
NB: SOME FORM OF LOCKING MUST BE USED IFTHE LATHE IS
CAPABLE OF REVERSE MODE.
CHUCK OPERATION
Adjustment: The Nova G3 chuck features a chuck key, which locates easily and quickly
intothe gearing mechanism.The high poweredgearing delivers outstandinggrip at little
effort.Moving in a clockwise direction will expand
thejaws outwards (expansion),and moving the key
in an anti-clockwise direction will contract the jaws
inwards(contraction). Forexample, move thehandle
in an anti-clockwise direction to move the jaws to
clamp a work piece inside the jaws, and then move
the handle in a clockwise direction to release the
work.
MOUNTING & DISMOUNTING OF JAWS
The Nova G3 chuck comes with no jaws attached. With the many jaws available it is
very easy to use your single chuck for a very wide range of applications.All jaws in
theTeknatool range for the Nova G3 are secured and attached the same way.
Attaching Jaws - To mount the jaws to the Nova G3 chuck is another easy
process. Firstly wipe clean all jaw slides, especially the contact surfaces. Repeat
this with all four jaws you wish to attach. Jaw slides are numbered one to four and
have a corresponding jaw - of the same number. This may be represented by dots if
numbers are not present, i.e. 3 dots = #3. Place a jaw on its correct jaw slide and
positioninto the groove (locationring out from thejaw into the groove of the jaw
slide). The first few times, you may need to GENTLY tap the jaws into the locater
slot with a block of wood or plastic mallet. Place M6X10 counter sunk screws in
jaws and screw them to finger tightness. When both screws are in nip them up and
back off half a turn. Repeat this to the remaining three jaws. Now using the Chuck
key, scroll all jaws towards middle until they all come together. Now with all jaws
touching and equal pressure on each, tighten all screws up. This will eliminate any
run out. Ensure that there are no gaps between the jaws. If a gap does appear, it will
probably be due to a jaw being placed on its wrong number (e.g. a #2 jaw on a
#3 jaw slide).
To Remove Jaws - Simply using the 4mmAllen key supplied, unscrew all M6
counter sunk screws (there are eight of them). The jaws will come away once their
screws are released. Sometimes due to dust particle build up (after heavy turning)
the jaws may need a very light tap with a plastic hammer to dislodge them. It is
important to keep them in their set so not to mix them up with other jaws of the
same type.
IMPORTANT NOTE:
Accessory Jaws: Although the Nova G3 is compatible with all the Teknatool Accessory Jaws, it is not
recommended that the larger accessory jaws be used, as they will hold work to larger capacities than is
recommended with the Nova G3. For instance, we do not recommend that the following accessory jaws
are used with the Nova G3: 130mm Jaw (JS130N),PowerGrips (PJSN), Titan PowerGrips (13029)
Moreover, it is not recommended that work exceed a diameter of 14” and a depth of 5” with this chuck.

The woodworm screw is made complete with the boss section in one piece. The
woodworm screw is to be used with the jaws remaining on the chuck. This facility is
very convinent for remounting work directly onto the jaws after the screw is removed.

USING THE WOODWORM SCREW (contd.)
To convert to this operation , place the boss section into the centre of the chuck and close
jaws into the slots. BEFORE FINALTIGHTENING MAKE SURE THATTHE FRONT OF THE
BOSS SECTION OF THE SCREW IS SEATED BEHIND AND AGAINST THE 50mm (2
INCHES) JAWS. This will prevent any tendency for the boss section to creep forward when
the screw is being used. NB: Recommended pre-drill size is 9/32” (7mm) for soft woods
and 5/16” (8mm) for hard woods.
The front face of the jaws have been machined to provide an accurate backing surface.
This is quite an advantage, providing a much tighter fit and wider tolerance for irregularly
faced 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 to be put straight onto the jaws
(the screw is first removed) after the recess has been formed.
The woodworm screws provides 15mm -1/2mm OR 39/64” (0.609”) of thread beyond the
jaws. 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. DO NOT USE THE SCREW FOR VERY LARGE WOOD BLANKS. Its intended for
small bowl and screw chucking work. The maximum capacity which should be mounted
on the screw is 250mm (10 inches) diamter X100mm (4 inches). DO NOT EXCEED 600
RPM FOR THIS OPERATION, and use tailstock with a live centre for support.
SPIGOT OPERATION
This is where the jaws contact 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.
EXTREMECAUTIONWITHTHIS OPERATIONMUSTBEEXERCISED. DONOTEXCEED850 RPM
FOR THIS OPERATION. If used properly, the Nova G3 Chuck provides a very powerful and secure
grip in this mode.
Instructions below apply to the standard 50mm (2 inches) 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 standard set of
50mm (2 inches) jaws a maximum size woodblank of 100mm (4 inches) diameter (NOT spigot
size) by 150mm (6 inches) length can be turned. Square timber of same length and between
40mm (1.5 inches) to 50mm (2 inches) and grip of all four jaws into wood. MAKE SURE YOU HAVE
ANADEQUATE 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:
Standard Jaws will grip a round spigot between 45mm (1 49/64inches) to 65mm (2 5/16 inches)
approx. Square timber between 40mm (1 37/64inches) to 50mm (2 inches) square approx.
Jaw slides only - With the 50mm (2 inches) add-on jaws removed, the jaw slides will grip either
round or square timber down to 8mm (5/16inch). Length limits are the 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 850 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
ONLYAREAFOR GRIP. IFANYWEAKNESS ISFOUND,DO NOTPROCEED.Mount woodbetween
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. The
50mm (2 inches) standard jaw has a thin lip (or shoulder at the front face) which is designed to
bite into the timber as the jaws are tightened. DO NOT CUTARECESS FOR THE LIP TO FIT INTO,
AS THIS WILL REDUCE GRIPPING POWER.
FORMING RECESS
The jaw dovetail has been designed for use with a standard skew scraper. This chisel will make
arecess to theangle required. FORSAFETYREASONS WESTRONGLYADVISEAGAINSTUSING
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 toolrest. Then revolve blank by hand
thus creating a pencilled circle. However, as specified above, any recess
diameter can be made between 50mm (2 inches) - 75mm (3 inches) 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 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
BOWLIS NOTINCORRECTLYRIDING ONTHE FLATSHOULDERSECTION OFTHE JAWS BEHIND
THE DOVETAIL. THIS COULD LEAD TO THE BOWLDISLODGING FROM CHUCK. LOOSEN JAWS
ANDREMOUNT 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 give an extra nip up. Refer to Chuck Operation. Refer again to safety
before operation.
