All the NOVA jaws are specially designed to provide maximum grip expanding into a
mortis/recess or contracting around wood tenons/spigots of varying sizes and
shapes. NOVA chucks can instantly swap from the expansion mode to the contracting
mode, with no adjustments or extra fittings being necessary. Any mortis/recess or
tenon/spigot size can be selected between the minimum and maximum range of the
jaws. The jaw slides (accessory jaws removed) can be used to grip small
tenons/spigots.
ACCURACY: The PRO-TEK SUPERNOVA2Chucks are sample tested from each batch
and are made to run within the following tolerance limits measured on the 50mm
(2”).
PRO-TEK Jaws:
Face/Axial Runout (X Axis) Maximum: 0.08mm (0.0031 inch)
Radial Runout (Y Axis) Maximum: 0.15mm (0.0060 inch)
Testing is performed with the chuck mounted with a standard NOVA threaded insert.
However, it is well to note that wood is a plastic material – with different densities
even in the same piece, and liable to warp out of place while turning. This is a part of
the beauty and appeal of working with wood. However, under these circumstances
pursuing accuracies (as above) with mounted wood can be difficult to achieve. For
most woodturning situations (with some expectations) there is little need to achieve
such tolerances.

General Health and Safety Guidance
ATTENTION: Please carefully read and understand the instructions in this manual
before assembly, installation and use of your PRO-TEK SUPERNOVA2Chuck.
Keep these instructions in a safe place for future reference.
WARNING: This chuck can contribute 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. NOVA also recommends joining a woodturning
club.
As with other work holding methods, an extremely cautious and sensible approach
is necessary. With the PRO-TEK SUPERNOVA2chuck 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 always be
used. Everyday spectacles are 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

7
unless workpiece is firmly clamped.
WARNING LATHE SPEED: 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 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 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.
As above 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 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.
JAW SLIDES: For safe operation do not extend the jaw slides beyond the chuck body
under any circumstances.
Wherever possible stand to one side of the revolving wood.

8
WEAR SUITABLE CLOTHING. Do not wear any loose clothing, neck ties, gloves,
bracelets, rings, or other jewelry 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, or have machines fitted with a Striatech drive system using the password lock
feature

Operation of the chuck
Main functionality of the chuck is to grab and secure the workpiece by expanding or
contracting its jaw slides. The jaw slides of the chuck can be operated by using the
provided t-handle.
The image below illustrates how the chuck can be operated:
Mounting the jaws onto the chuck
The PRO-TEK SUPERNOVA2chuck is supplied with a set of Pro-Tek 50mm jaws
(#6075). The jaws must be securely fastened for the chuck to serve its function
correctly. Mounting procedure of the jaw applies to all NOVA accessory jaws.
Please follow the steps below when mounting the jaws onto the chuck:
1. Ensure there are no dusts or debris
on the bottom surface of the jaw
and top surface of the jaw slides.
2.
Each jaw segment has a number
indented on the jaw edge to
indicate its correct mounting
position for
minimal runout.
Loosely screw the jaw segment
onto the jaw slide with the number
matching the jaw slide. The
Open
Close

14
numbering should be 1,2,3,4 in a
clockwise direction.
Note:
The jaw segments should slightly
rattle by hand at this point.
3.
Tightly close the jaw
slides until all
side surfaces of the jaw segments
meet
one another and no lights can
be seen between the jaw segments
4.
Fully tighten all
the jaw segment
mounting screws by using
NOVA
Star Head T-bar handle supplied.
Removing jaws from the chuck
Simply remove the jaw mounting screws by using the supplied NOVA Star head
wrench to dismount the jaw segments from its jaw slides.
Tip:
There may be occasions where the jaw segment seizes on the jaw slide which poses
difficulties when attempting to remove the jaw slides by hand. Use a soft hammer
(mallet) to gently tap either side of the jaw segment to dislodge it out from the jaw
slide.

15
Mounting the chuck onto a lathe
There are two configurations available for the PRO-TEK SUPERNOVA2Chuck:
•Insert model-Requires an insert adapter for chuck to be mounted on the lathe.
See full list in this manual of the NOVA (lathe spindle thread) insert adaptors
available.
•Direct Thread model: M33 ASR Eurolock
Both configurations will require identical procedures to be correctly mounted onto
the lathe however the insert version will require an insert adapter to be screwed into
chuck and then mounted onto the lathe.
The image below illustrates an insert version chuck mounting procedure on the lathe
however, identical procedures will apply for the direct threaded version:
1. If the chuck is an insert model,
ensure the insert is bottomed out
on the chuck body before mounting
on the lathe.
2.
F
or both Insert & Direct Thread
model: Wind the chuck on the lathe
spindle until the chuck comes firmly
in contact with the bearing/ spindle
shoulder with no gaps in between.
Note:
Make sure there is no grub
screw threaded onto the chuck
body or insert bef
ore threading
onto the lathe spindle.
Important:
Left hand thread inserts
must be locked to chuck body or
chuck body could unwind from
insert.
3.
Firmly tighten the chuck body/
insert using a chuck spanner
(Sold separately; SKU 23079)

4.
Place the red thread protector
washer into the M6 threaded
hole indicated in the image. Then
wind the M6 grub screw in
position and
tighten with 3mm
Hex head wrench (provided)
which prevents the chuck from
loosening from the lathe spindle.

17
Mounting the chuck using the ASR Eurolock locking ring
The M33 version NOVA lathes and chucks have a special locking coupler to prevent
the chucks from coming loose and detaching from the lathe spindle. The ASR Eurolock
locking ring is exclusive to the M33 version lathes and chucks.
Note:
The locking ring is not compatible with lathes and chucks that are not the M33 ASR
Eurolock model.
Below are the steps on how to attach the EU
locking ring:
Step 1:
Tighten the EU 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 Hex key to tighten up two bolts on
the locking ring.

18
Screw chuck – Safe Lock Woodworm Screw
The Safe Lock woodworm screw (screw chuck) provides a convenient method for
holding a bowl blank to cut a recess or spigot to mount on an accessory jaw.
The accessory jaw segments must be properly mounted beforehand to use the
woodworm screw. The woodworm screw is to be mounted inside the centre hole of
the chuck as shown below:
Open the jaw slides and insert the
Safe Lock Woodworm screw in
the center hole of the chuck.
Position the Safe Lock
Woodworm screw as shown as
the image.
Note:
All 4 flat sides of the
Safe
Lock
W
oodworm screw should be
in contact with the flat end of the
jaw slides.
Make sure this flat face of the
Safe Lock Woodworm screw
comes
in contact with the flat
surface
of the jaw slide

19
To use the Safe Lock Woodworm screw on a workpiece
1. Ensure the workpiece surface facing
the jaw segments that is flat as
possible.
2.
Drill an 8mm(.31”)
diameter hole at
approximately 19mm(0.74”)
deep
into the work piece
3.
Firmly press the
Safe Lock
Woodworm screw into the pre
-
drilled hole on the workpiece and
thread the workpiece onto the wood
worm screw until the workpiece
makes good contact with the
mounted jaws on the chucks.
Caution – Maximum capacity and speed of Safe Lock Woodworm screw:
DO NOT USE THE SCREW FOR VERY LARGE WOOD BLANKS. The Safe Lock
Woodworm screw 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 whenever
possible.

Forming a Mortis/Recess or Tenon/Spigot
There are two main types of technique used to hold a workpiece onto the chuck:
Tenon (Spigot) and Mortis (Recess).
In either case, to form a dovetail in the mortis/recess or on a tenon/spigot, the
workpiece must be securely mounted on the lathe with a woodworm screw (Or
equivalent such as a faceplate or between centres).
Note: There are two main types of technique used to hold a workpiece onto the
chuck: Mortis/Recess and Tenon/Spigot.
In either case the forming of a proper dovetail will ensure that the jaws will perform
to their maximum ability.
Note:
The procedures below show the general formation and uses of both the
mortis/recess and tenon/spigot. However, it is up to the user’s experience to
determine the ideal size of the recess and spigot size based on the jaws they are using.
Safety Concerns when turning
IT IS RECOMMENDED TO USE THE TAILSTOCK FOR ADDITIONAL SUPPORT
WHENEVER POSSIBLE. BY NOT CHUCKING UP YOUR PIECE PROPERLY, YOU RISK
YOUR PIECE DISLODGING FROM THE CHUCK
