FOR YOUR SAFETY

PLEASE READ & UNDERSTAND THIS INFORMATION BEFORE USING YOUR NOVA G3 CHUCK

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.

BEFORE USING THE NOVA G3 CHUCK MAKE SURE THAT -

• EYE PROTECTION WHICH COMPLIES WITH CURRENT ANSI STANDARD Z87.1 (USA) IS

WORN. WE RECOMMEND THAT A FULL FACE SHIELD BE USED AT ALL TIMES.

• Chuck is properly secured on lathe spindle. Follow mounting instructions for your lathe for

faceplates and other spindle fixtures.

• For safety, DO NOT ROTATE CHUCK UNDER POWER WITHOUT WOOD BEING GRIPPED.

• WARNING: EXCESSIVE SPEED IS A SERIOUS LATHE HAZARD. ALWAYS TURN AT THE

SLOWEST SPEED POSSIBLE.

• Speed will vary with wood blank size. The larger the blank the slower the speed. Consult

your lathe manual or lathe information plate for speed guidelines.

• DO NOT ATTEMPT TO USE THE CHUCK UNLESS THE LATHE SPEEDS ARE KNOWN,

YOU MUST STRICTLY FOLLOW THE MAXIMUM SPEED LIMITS SET OUT IN THE

OPERATING SECTION OF THIS MANUAL.

DO NOT EXCEED THEM UNDER ANY CIRCUMSTANCES.

• EXAMINE WOOD CAREFULLY. ONLY MOUNT WOOD THAT IS SOUND, If any cracks, splits,

or weakness is found in wood - DO NOT MOUNT ON CHUCK. DO NOT MOUNT ANY

WOOD THAT IS LIKELY TO BREAK UP DURING TURNING (E.G. ROTTEN OR SPONGY

WOOD). DO NOT USE POORLY JOINTED or LAMINATED WOOD.

• Make sure wood is clamped firmly. Follow mounting instructions for different gripping

modes and jaw types. In the expansion mode do not use undue force or jaws may split

the wood.

• Do not exceed maximum guidelines in this manual for wood blank diameters or lengths

set out in this manual for different modes and jaw types.

DO NOT USE WITH ANY COPYTURNER OPERATIONS.

• Check wood is securely held in chuck, before operation. Check grip by vigorously

wrenching wood blank back and forth. If any loosening occurs, re-examine holding area

for adequate grip (Following mounting guidelines) and any damage to holding area.

Rotate manually to make sure of clearance before switching power on.

• WARNING: FOR SAFE OPERATION

IT IS RECOMMENDED THAT TURNING BE CARRIED OUT WITH JAW SLIDES

NOT EXTENDING BEYONG THE CHUCK BODY. HOWEVER THE JAW SLIDES

CAN EXTEND ABOUT 6.35MM (1/4”) BEYOND THE BODY OF THE CHUCK TO

GIVE A WIDER RANGE OF EXPANSION, IF REQUIRED. EXTRA CAUTION MUST

BE EXERCISED WHEN TURNING WITH JAW SLIDES EXTENDING BEYOND

THE BODY OF THE CHUCK.

• Irregular or out of balance stock needs to be turned at the slowest possible speed until it

is in balance. For use on outboard/left-hand rotation - MAKE SURE INSERT IS SECURELY

LOCKED WITH GRUBSCREW BEFORE USE. Use only hand held woodturning chisels to

shape wood being held in chuck.

• USE THE RIGHT CHISEL FOR THE JOB AND DO NOT FORCE TOOLS. Use safe and

commonly approved chisel techniques. Wherever possible stand to one side of the

revolving wood.

• WEAR PROPER CLOTHING. Do not wear any loose clothing, neck ties, gloves, bracelets,

rings or other jewellery that could get caught in moving parts. Wear protective hair covering

to contain long hair.

• Do NOT operate chuck or lathe while under the influence of DRUGS, ALCOHOL or any

MEDICATION.

• KEEP CHILDREN AND VISITORS AWAY. All children and visitors should be kept safe

distance from the work area.

Make workshop childproof with padlocks, master switches, or by removing starter keys.

Thank you for purchasing your Nova G3 Chuck - the latest addition to our Woodturning Chuck

range. We are confident that it will be a great aid towards fast workholding and enhance your

woodturning capablity. The Nova G3 is designed for a range of woodholding modes while being

quick and easy to use.

NOVA G3 CHUCK

INSTRUCTION MANUAL

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

will run true. If further modifications are needed (e.g. spacer) these are the

responsibility of the user. A good check is to see whether it screws home the same

as a faceplate or similar spindle fitting.

DO NOT USE UNLESS CHUCK IS PROPERLY FITTED TO SPINDLE.

NB: SOME FORM OF LOCKING MUST BE USED IF THE LATHE IS

CAPABLE OF REVERSE MODE.

CHUCK OPERATION

Adjustment: The Nova G3 chuck features a chuck key, which locates easily and quickly

into the gearing mechanism. The high powered gearing delivers outstanding grip at little

effort. Moving in a clockwise direction will expand

the jaws outwards (expansion), and moving the key

in an anti-clockwise direction will contract the jaws

inwards (contraction). For example, move the handle

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

the Teknatool 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

position into the groove (location ring out from the jaw 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 4mm Allen 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.

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 100mm (4 inches).

Characteristically these items have a parallel wood grain. IT MUST NOT BE USED FOR

ANY LONG WORK (OVER 100mm or 4 inches) AS THERE WOULD BE GREAT DANGER

OF WOOD TEARING OUT AND DISLODGING FROM CHUCK.

Instructions below apply to the standard 50mm (2 inches) 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 standard 50mm (2 inches) jaws, you can turn bowls

up to 350mm (14 inches) in diameter. DO NOT EXCEED 600RPM WITH THIS OPERATION.

OUT OF BALANCE STOCK MUST BE TURNED AT THE SLOWEST SPEED POSSIBLE.

50mm jaws - Any recess can be turned between 50mm (2 inches) and 70mm (2

3/4”

inches)

diameter. For smaller lids and thin platters (not exceeding 150mm or 6 inches diameter) only

a shallow recess of around 3mm (1/8 inch) is necessary. It will be matter of gaining

experience as to what combinations and sizes will best suit.

Publication Number: 110-0706-001

AUTO STOP FEATURE

The Nova G3 has an in built safety feature which

prevents the jaws slides from becoming disloged

from the chuck. The auto stop feature is first in the

industry doing away with shearing screws.

PARTS LIST & EXPLODED DRAWING

USING THE WOODWORM SCREW

The woodworm screw supplied with the Nova G3 chuck 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 fibers. They grip better than screws 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 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.

NB: Direct threaded chucks #9 & #10 not used

(with the exception of the 4-threaded direct chuck)
