EXPANDING 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. Specific sizes for each jaw type is stated in
that area. Please refer to your NOVA Chuck manual for information on how to form a recess.
When making a recess it is important to calculate the depth. The recess depth is an important
consideration for maximising the holding power of the jaws, guidelines under each jaw should
be followed closely. The depth of a recess can be varied according to the size and mass of the
workpiece. Larger bowls and softer woods require a deeper recess. Smaller lids and thin platters
generally require a shallower recess. Always use a recess depth in excess of what is required.
IF THERE IS ANY DOUBT INCREASE RECESS DEPTH.
SPIGOT (Tenon) OPERATION
Contraction of the jaws around a wooden spigot for grip. Mainly used for box, goblet and vase
turning, that is, endgrain items with a fair degree of overhang. Generally tailstock support is
minimal or cannot be used because of the need to hollow out the inside. This method seems to
be preferred by many bowl turners over the internal dovetail recess as the foot can later be
re-shaped or removed, if desired, to make a smooth outside bottom of the bowl.
This situation is one of the most difficult to provide secure holding no matter what fixing method
is used. EXTREME CAUTION WITH THIS OPERATION MUST BE EXERCISED. If used properly
however, Teknatool Chucks provide a very secure grip in this mode.Check for adequate contact
and grip of all four jaws into the wood when using this operation.
MAKE SURE YOU HAVE AN ADEQUATE GRIP BEFORE OPERATION by vigorously wrenching
the work piece mounted in the chuck.If any loosening occurs DO NOT PROCEED with operation.
Repeat tightening procedure and retest grip. Refer to your NOVA chuck manual for information on
forming a spigot.
FREE END TURNING
Turning where the work is not supported by the tailstock. Commonly used for all hollow form
work such as bowls, long hollow vases or boxes.
TROUBLESHOOTING GUIDE
PROBLEM
Add on jaws do not run true
POSSIBLE CAUSE AND SOLUTION
Check jaws are mounted correctly on jaw
slides. For method see Page 9. For accuracy
parameters see Page 2. When the jaws are
expanded beyond a 50mm circle they will
appear to be running out but in fact are
maintaining concentricity. Always evaluate
runout from turned wood clamped in jaws
PROBLEM
Accessory Jaws when Wound to
centre do not meet
POSSIBLE CAUSE AND SOLUTION
Slides have not engaged sequentially in
clockwise order with scroll - 1-2-3-4. Jaw Slides
could have been inserted out of order.

Explanation of
common chucking techniques
OPERATIONAL MODES
Refer to the tables over and please note that
sizes are a guide only, actual sizes may vary.
Expanding Dovetail Jaws
THIS METHOD MUST NOT BE USED FOR ANY
WORK LONGER (BOWL DEPTH) THAN 150MM
AS THERE WOULD BE GREAT DANGER OF
WOOD TEARING OUT OF THE CHUCK. DO
NOT EXCEED 700RPM IN THIS MODE. OUT
OF BALANCE STOCK MUST BE TURNED AT
THE SLOWEST SPEED POSSIBLE.
Any recess diameter can be turned between the
max and min Expansion limits of the particular
jaw as in the table above. The optimum turning
recess diameter (on the outside) is as close to
the minimum (detailed above) as possible. As
the recess diameter is increased above the
optimum, less jaw contact is made. Take care
not to make the
Reverse Dovetail (Contracting Action)
This method is used to grip bowls with a foot
mounting. The size of the foot being between
the min and max contracting sixe of the jaw as
in the table above. The optimum foot diameter
is about the minimum contracting foot size of
the jaw. Larger foot diameters can be used
but above the edges of the jaws can mark the
wood. It is suggested that masking tape is used
to protect the foot from jaw marks.
Spigot (Tenon) Mounting (Contracting
Action)
Wood should be pre-machined to a cylinder (to
optimize balance) with a diameter no greater
than max clamping diameter of the jaw. This
method can be used to grip pre-machined/pre-
turned spigots.
SPIGOT SIZE SHOULD BE WITHIN
CONTRACTING LIMITS AND USE FULL
SPIGOT LENGTH OF JAWS, AS
DETAILED IN TABLE OVER.
MOUNTING ADD-ON JAWS
1.Using the supplied Chuck Key, turn the
chuck pinion gear clockwise to open the jaws
to their outer most position (as in Figure 1).
IMPORTANT: Never leave the Chuck key in
the chuck when not in use!
2. Push in the Lock Push Pin on the back of the
Jaw Side Using the pin in the end of the Chuck
Key Handle to release the locking mechanism
(Figure 2).
3.With the Lock Push Pin fully depressed in,
position a desired jaw on the left side of a
free Jaw Slide and slide the Jaw clockwise in
a circular motion into place in the Jaw Slide.
Remove the Pin holding the lock push pin in
and ensure the jaw is securely locked in place.
(Figure 3).
Repeat for all remaining free Jaws.
2. With the jaws opened to their outermost
position, push in the Lock Push Pin on the back
of the Jaw Side using the pin in the end of the
Chuck Key Handle to release the locking mecha-
nism (Figure 4).
1. With the Lock Push Pin fully depressed
in, slide the Jaw anti-clockwise in a circular
motion Out of the Jaw Slide. Remove the Pin
holding the lock push pin. (Figure 5).Repeat for
all remaining Jaws.
MAINTENANCE
Before each use wipe clean the base of the
jaws and dovetail key to make make sure the
jaw gets proper surface contact when
mounting.
Clean jaws after use and spray with a light
Corrosion protectant product like WD40 or
CRC.
Additionally, for longer term storage, wrap in
an oil soaked cloth.
NOTE: if the collet is not coming out of the Chuck, check the Lock pin is fully depressed.
If it is and the jaw still can’t be removed, lightly tap the jaw anti-clockwise out of the Chuck.
