SCREW CHUCK - WOODWORM SCREW
The woodworm screw (screw chuck) provides a convenient method for holding a bowl blank
to cut a recess to mount on the 50mm (2in) jaws.
Jaws must be mounted on the chuck before the wood worm screw – See diagram
Open the jaw slide and insert the wood
worm screw in the centre hole of the
chuck.
Position the woodworm screw as shown
in illustration.
Note: All 4 flat sides of the wood worm
screw should be in contact with the flat
end of the jaw slides.
The wood worm 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 A SPIGOT OR DOVETAIL
Spigot is where the jaw contracts onto the workpiece shaped to
a cylinder. 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.
Spigot Diameter (For P RO -T EK 50mm (2in) Jaws)
Min Diameter Max Diameter
Cylinder 45mm (1 3/4in) 65mm (2 9/16in)
Square 40mm (1 9/16in) 50mm (2in)
Dovetail is where the jaw expands into a recess of a workpiece
to grip. This operation is mainly for bowls and platters (Items
with parallel wood grain).
IT MUST NOT BE USED FOR ANY LONG WORK (OVER 100mm or
4 inches). DO NOT EXCEED 600RPM WITH THIS OPERATION.
OUT OF BALANCE STOCK MUST BE TURNED AT THE SLOWEST
SPEED POSSIBLE.

Min Max
50mm (2in) 70mm (2 3/4in)
FORMING A SPIGOT OR RECESS
Recess Spigot
Using a Nova Dovetail Chisel #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 profile of between
75~80deg with 10mm (25/64 in.) depth.
Using a suitable chisel, turn the outer
diameter of the wood to form the spigot.
The length of the spigot should match the
internal height of the jaws.

ACCURACY
The P R O - T E K S UPERNOVA 2 Chucks are sample
tested from each batch and are made to run within
the following tolerance limits on the P RO -T EK 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.
