Home Why a NOVA Chuck?
Why a NOVA Chuck?
We were the first company to introduce one of the biggest innovations for woodturners, the 4 jaw self centering
chuck in 1988. This chuck revolutionized how work was held in woodturning. We continue this proud tradition
of innovation, quality and best value.
The G3, SuperNOVA2 and Titan III Chucks are key operated, 4 Jaw Self Centering Scroll Chucks. The Precision Midi
is a lever operated, four jaw self centering scroll chuck. All accessories are interchangeable between our standard chucks.
NOVA is the only chuck manufacturer to offer this flexible and money saving feature. We offer the best quality,
features and price. You can purchase chuck accessories in confidence knowing that if you wanted to upgrade your
chuck options that your accessories haven’t changed.
The following factors should be considered when choosing which NOVA chuck best suits your needs:
– Ease of use and power of clamping
– Size of wood/project
– Spindle Size Required
COMMON FEATURES OF OUR CHUCKS
Original NOVA Self Centering Design
All of 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.
Auto Safety Stop Feature
Our chucks are designed with an automatic safety stop built into the jaw slide. This prevents the jaws from
protruding beyond the chuck body, providing safe turning conditions.
Common Accessory Jaw Fixing Profile
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. 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. Only NOVA has this unique interchangeability.
Special Woodturning Dovetail Profile on Jaws
NOVA Chuck jaws feature a special woodturning dovetail profile. Some chucks use an engineering profile,
designed to hold hard material like steel. Other chucks use a rounded profile which will crush the wood fibers
without digging in and holding securely. There are a number of schools of thought as to what is the best profile.
The Nova Dovetail Jaw profile works in harmony with the wood and provides the highest gripping performance
without damaging the wood. We have a large number of styles of the Dovetail Profile, providing light non marking
grip to the very powerful PowerGrip™ series. The style choice is dependent on the type of turning and hardness
of the wood.
Insert/Adaptor System for NOVA Insert/Adaptor chucks (not compatible with the Direct Threaded chucks)
We can fit to over 100 different lathes, so there is bound to be one to fit your lathe. For thread sizes, see here. If you
purchase a new lathe or want to put your chuck on a different lathe, this flexible system makes it as easy as buying a
new insert/adaptor. Chucks that come pre-threaded (Direct Threaded) into the chuck body cannot take an Insert/Adaptor system.
We also have some Direct 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 minimizing run out. It is manufactured in a single operation with spigot location to give excellent accuracy.
Safe Lock™ Woodworm Screw
Nova was the first to introduce the Woodworm™ Screw when it was released with the original NOVA chuck in 1988.
All Nova Chucks are supplied with a Safe Lock™ Woodworm screw. The form of the screw has a deep fine blade
machined to the end of the screw. This allows an easy lead into wood. It features a square shank and a locating
groove so it can lock positively into the Nova chuck body.
Precision Machining and Quality Materials using 21st Century Manufacturing Techniques
High Tech Composite Jaw Slides
Jaw slides are made with high tech copper fused steel for maximum hardness, wear and self-lubricating properties.
The slides feature strong and large section guideways with a 6mm tongue. The large surface area provides long term
load bearing surface wear and resistance. This is 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 chuck’s range are recommended.
Composite Indexing Backing Plate (SuperNOVA2)
Made from ultra tough Duracon™ composite reinforced with stranded glass fibers for long life in tough conditions.
Self lubricating properties and unique built in indexing function.
Precision investment cast in high tensile carbon steel and hardened to exact tolerance after heat treatment. Ensures
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
unshakable grip. This extra holding strength and stability decreases any vibration. You can extend much longer from
small delicate stems up to large rugged pieces.
Precision Machining and High Quality Materials
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. We use a polished self metal finish to allow for closer tolerances
and accuracy. Nickel plating is an old, outdated technology that we no longer use.
