LITE G3 CHUCK
QUICK START
INSTRUCTION
MANUAL
Thank you for purchasing the NOVA LITE G3 Chuck –a new addition to our NOVA woodturning
chuck range with advanced features to enhance your chuck performance. It provides a
versatile and easy method for fast and secure work holding for all face turning –bowls,
egg cups, vases, boxes, goblets and an endless variety of similar projects.
OPENING AND CLOSING OF JAWS
MOUNTING THE LITE G3 CHUCK
ON THE LATHE
There are two configurations available for the LITE G3 chuck:
•Insert model: Requires an insert for chuck to be mounted on the lathe. See full manual
online for a list of lathe spindle thread inserts available.
•Direct Thread model: Threads directly on the spindle directly available in M33 and 1”8TPI.
1. If the chuck is an insert model,
ensure the insert is fully seated in
the chuck body before mounting
on the lathe.
2. For both Insert & Direct Thread
model: Thread the chuck on the
lathe spindle until the chuck comes
firmly in contact with the
bearing/spindle shoulder with no
gaps between.
3. Place the red thread protecting
fibre washer into the M6 threaded
hole. Then screw the 6mm grub
screw in position and tighten with
the provided 3mm Allen Key to
prevent the chuck from loosening
on lathe spindle.
*Using the ASR M33 Thread locking ring (Only applicable to ASR M33 model)
Step 1:
Tighten the ASR M33 chuck to the spindle on
the lathe, make sure the rings on the spindle
and chuck have been clamped.
Step 2:
Put the lower part of locking ring under the
clamped rings.
Step 3:
Put upper part of the locking ring to the
clamped rings as well.
Step 4:
Using the Allen key to tighten up two bolts on
the locking ring.
YOUR SAFETY
Keep these instructions in a safe place for future reference.
WARNING: This chuck is capable of contributing to serious injury (as with any other
power tool accessory) if this manual guidance is not followed or if it is used improperly
on the lathe. Read and understand 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
or other expert tuition is recommended.
As with other work holding methods, an extremely cautious and sensible approach is
necessary. With the LITE G3 Chuck it is not possible to give exact directions as to the
amount of tightening pressure required for adequate work holding or approved chisel
cutting techniques. Follow closely strict guidelines in this manual for different jaw
types on wood blank diameters and length, plus strictly follow recommended lathe
speeds.
Safe Operation:
Eye Protection: Woodturning operations can result in objects being thrown into your
eyes which can result in severe eye damage. Protective eye wear must be used at all
times. Everyday vision wear is not protective eye wear. We recommend a full-face shield.
Always wear eye protection which complies with current ANSI Standard Z87 (USA).
Noise Protection: Use ear plugs or ear defenders. Particularly if the noise exceeds 85dB.
Exposure to high levels of noise can lead to hearing problems.
Dust Protection: Use respiratory protective equipment (dust mask, portable respirator
device). Exposure to high levels of irritating dust when turning or sanding hardwoods,
soft woods and manufactured composite boards (MDF) can result in serious health
problems. In addition, adequate workshop dust extraction must be used.
Chuck is properly secured on lathe spindle: Follow mounting instructions for your lathe
for faceplates and other spindle fixtures. Do not rotate chuck under power unless
workpiece is firmly clamped.
WARNING: LATHE SPEED: Excessive speed is a serious lathe hazard. Always turn at the
slowest speed possible. Ideal 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 recommended lathe speeds to
size of wood blank are known. In addition, you must strictly follow the maximum speed
limits set out in the operating section of this manual. Do not exceed them under any
circumstances.
CHECK WORKPIECE: Examine wood blank carefully before mounting on chuck/lathe.
Only Mount Wood that has no cracks, splits, holes, or any other weaknesses (e.g. rotten
or spongy sections). Do not use poorly jointed or laminated wood. Irregular or out of
balance stock needs to be turned at the slowest possible speed until it is in balance.
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/length set
out in this manual for different modes and jaw types.
Check that the 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.
DUPLICATOR OR JIGS: Do not use chuck for work holding with a duplicator or jigs.
Safe Practice:
CHISEL USE: Use only handheld woodturning chisels to shape wood being held in chuck.
Use the recommended chisel for the job. Use safe and commonly approved techniques.
WARNING: Never attempt to place hands on a moving chuck on a lathe. Wait for the
chuck to come to a complete stop before hands are anywhere near the chuck. Trying to
grab at a moving chuck could result in SERIOUS INJURY. Jawslides: For safe operation do
not extend the jawslides beyond the chuck body under any circumstances.
Wherever possible stand to one side of the revolving wood.
WEAR SUITABLE 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.
DRUGS, ALCOHOL, MEDICATION: 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.
ATTACHING AND REMOVING JAWS FOR
LITE G3 CHUCK
The LITE G3 chuck comes included with a set of 50mm add-on jaws.
The jaws must be properly attached on the chuck to function as intended.
Before installation, ensure the jawslide top surfaces are clear of any dust or debris before
attaching the jaws on the chuck.
Follow the steps shown below to attach the jaws on the chuck:
Firmly tighten the NOVA Hex screws using
the included 4mm Allen Key.
To remove the jaws, loosen and remove the
NOVA hex screws from the chuck.
Tip: After removal, wipe down the jaws and
add rust protection before storing.
Always mount the jaws clockwise, using the
number indented on the underside of the
jaw for correct mounting sequence (1,2,3,4).
Loosely attach the jaw segments on the
jawslide with the NOVA hex head screw
included and firmly close the jaws to make
sure no light is visible between the jaw
segments.

SCREW CHUCK - WOODWORM SCREW
The woodworm screw (sold separately) provides a convenient method for holding a bowl blank
to cut a recess to mount on the LITE G3 50mm (2in) jaws. Jaws must be mounted on the chuck
before the woodworm screw –See diagram. (Some models Woodworm sold separately, order
SKU 10006).
Open the jawslide and insert the
woodworm screw in the centre hole of
the chuck.
Position the woodworm screw as shown
in illustration.
Note: All 4 flat sides of the woodworm
screw should be in contact with the flat
end of the jawslides.
The woodworm screw is used to secure the wood to cut
either a recess or spigot on the open ‘face’ end.
Pre-drill a hole of size 8mm (5/16in) diameter with
19mm (3/4in) depth to mount the blank using the
woodworm screw. The wood must be seated firmly and
flat against the top surface of the mounted jaws. For
first stage rounding of bowl blanks, extra support can
be used with live centre support from the lathe
tailstock. See full manual online for more details.
DO NOT USE WOOD BLANKS LARGER THAN 250mm
DIAMETER X 100mm DEPTH (10inx4in)
DO NOT EXCEED 600RPM
TURNING ON A MORTISE OR TENON
Tenon is where the jaw contracts onto the workpiece to grip.
This is mainly for box, goblet and vase turning (End grain items
with a fair degree of overhang).
EXTREME CAUTION WITH THIS OPERATION MUST BE
EXERCISED. DO NOT EXCEED 850 RPM FOR THIS OPERATION.

Using a NOVA Dovetail Chisel SKU 6008 (or any
other suitable tool), cut into the wood, rest the
flat side of the chisel on the bottom surface of
the recess to form a dovetail profile of between
75~80deg with 10mm (25/64in) depth.
Using a suitable chisel, turn the outer
diameter of the wood to form the tenon.
The length of the tenon should be 3mm less
than the internal height of the jaws.

ACCURACY
The LITE G3 Chucks are sample tested from each batch and
are made to run within the following tolerance limits on the
50mm (2in) jaws:
-Maximum Face/Axial Runout: 0.08mm (0.0031 in)
-Maximum Radial Runout: 0.15mm (0.0060 in)
However, wood is a flexible material with varying densities
and liable to warp while turning.
Under these circumstances pursuing accuracies as above,
measured on the wood project clamped in the chuck, can be
very difficult to achieve. For most wood turning projects
there is usually little requirement to achieve such tolerances.
