We’ve
been making Woodturning equipment for over 27 years, and were the first company
to introduce one of the biggest innovations for woodturners; the 4 jaw self
centering chuck, with the
NOVA
chuck back in 1988. This chuck
revolutionised how work was held in Woodturning. We continue this proud
tradition of innovation, quality and best value in modern
NOVA
chucks today.
Today, we have 4 chucks in the
NOVA
Chuck Family:
The
G3,
SuperNova2 and Titan Chucks
are a key operated, 4 jaw self centering scroll chuck.
The Precision Midi chuck is a lever operated, four jaw self centering
scroll chuck.
All
accessories are interchangeable between our chuck models.
NOVA
are the only chuck manufacturers to
offer this flexible and money saving feature – you can confidently invest in
chuck accessories to further adapt your chuck product to suit your needs,
whilst knowing that if you ever wanted to upgrade your chuck options, your
accessories won’t have to be changed, too.
All of our
chucks are the result of many, many hours of input from woodturners, engineers
and mechanical specialists, not to mention over 27 years of chuck manufacturing
experience.
At
Teknatool International, we firmly believe in, and try to adopt best value in
every product, including the chucks. This means finding the best possible mix
between quality, features and price for you, the user of our products.

FEATURES
COMMON TO
ALL
OUR
NOVA
CHUCKS
Original
NOVA
Self Centering Design
All
our NOVA
chucks are four jaw, self centering
scroll chucks. This means that you don’t need to be exact in your
measurements for holding, and this design feature allows you flexibility in
both the expanding and contracting modes. The
four jaw design firmly grips both round and square wood.
NOVA
was the first company to bring this user
friendly design to Woodturners back in 1980, a design that has since been
copied and adopted by other chuck manufacturers - precisely because it is so
user friendly!
Auto
Safety Stop Feature
All of our
chucks are designed with an automatic safety stop built into the jaw slide,
preventing jaws from protruding beyond the chuck body, providing safe turning
conditions.
Common
Accessory Jaw Fixing Profile
NOVA
Smart Design. All
NOVA
Chucks use the same Jaw fixing profile,
which means that all appropriate accessory jaws can be fitted across the range
to any
NOVA
chuck. Only
NOVA
has this unique interchangeability.
You don’t have to change your accessories if you upgrade or change
your
NOVA
chuck. You only need to invest in one
set of accessories, saving you money.
Special
Woodturning Dovetail Profile on Jaws
 NOVA
Chuck jaws feature a special woodturning dovetail
profile proven over 27 years and many, many thousands of chuck users.
All
NOVA
Jaws will cut into
the wood fibres, gripping firmly and provide high tear out strength.
Some chucks use an engineering
profile, designed to hold hard material like steel.
 Others use a rounded profile, which will just crush the wood fibres
without digging in and holding securely. They just don’t understand the
nature of holding a flexible material like wood.
There are a number of
schools of thought as to what is the best profile.
It’s a bit like making furniture - some people appreciate the
craftsmanship of dovetail joints and equally people make furniture with MDF and
screw fastenings. The arguments about profiles for gripping wood for turning is
similar.
For the purest in woodworking
the perfection of the dovetail is only way to joint wood
- we use this principle in the dovetail jaw profile. The dovetail joint
was devised as the strongest joint to work in harmony with the nature of Wood.
Equally, the
NOVA
Dovetail Jaw profile works in harmony with the
work piece and provides the highest gripping performance, without damaging the
wood.
Nova
have a large number of styles of the Dovetail Profile,
providing from light non marking grip to the
very powerful PowerGrip™ series. The choice
is dependant on the type of turning and hardness of the wood.
Insert/Adaptor
System
 Every
NOVA
chuck takes our insert/adaptor for
fitting your NOVA
chuck to your lathe spindle. We can fit
to over 100 different lathes, so there is bound to be one to fit your lathe!
For thread sizes, see HERE. This
flexible system means that if you ever purchase a new lathe, or want to put
your chuck onto a different lathe, it’s as easy as buying a new cost
effective insert/adaptor.
We also have some dedicated threaded chucks for special large thread sizes.
The
insert/adaptor is precision machined from high strength K1045 medium tensile
carbon steel, and features a wide mounting face and accurate diameter register
for minimising run out.
Manufactured
in a single operation, with spigot location to give excellent accuracy.
Safe
Lock™Woodworm
Screw
All NOVA
Chucks are supplied with a Safe Lock™
Woodworm screw. The form of the screw has a deep fine
blade which is machined right to the end of the screw. This allows an
easy lead into the wood. The Safe Lock™ Woodworm Screw features a square
shank and a locating groove so it can lock positively into the
NOVA
chuck body.
NOVA
were the first to introduce the Woodworm™ Screw concept
for Woodturning Chucks, back in 1988 when it was released as a standard item
with the Original
NOVA
chuck.
Precision
Machining and Quality Materials using 21st Century Manufacturing
Techniques
High
Tech Composite Jaw Slides
 Made
with high tech copper fused steel for maximum hardness, wear, and
self-lubricating properties. The slides feature a strong and large section
guideways, with a strong 6mm tongue. The large surface area provides long term
load bearing surface wear and resitance.
NOVA
branded for genuine quality. The only
high tech jaw slide available in chucks on the market. This precision provides
exact and controlled tolerances which are required for Woodturning chucks. All NOVA
jaws have identical fixing method,
giving you ultimate flexibility – all accessory jaws will fit all chucks (of
course, only those accessory jaws that are appropriate for that particular
chucks’ range are recommended to be used) For more on the jaw slides,
download the fact sheet HERE.
Scroll
Precision
investment cast in high tensile carbon steel and hardened to exact tolerance
after heat treatment, to ensure long life and better wear resistance.
For the chucks where gearing is a feature (all except the
NOVA
Precision Midi) the special Tuff Lock™
gearing profile is designed with a wide, open formed tooth that gives a fast,
smooth action and unshakeable grip. This
extra holding strength and stability decreases any vibration – you can extend
much longer, through to small delicate stems through to large rugged pieces.
Body
 Precision
machined in one operation from a solid steel block for high accuracy. Made from
high quality K1045 medium tensile machine steel for optimum strength and wear. After
some years of using Nickel plating, we have rejected this as old, outdated
technology. We use a polished self
metal finish to allow for closer tolerances and accuracy.
