Teknatool LITE SUPERNOVA2, Instruction Manual

Page: 2 / 2

SCREW CHUCK - WOODWORM SCREW
The woodworm screw provides a convenient method for holding a bowl blank to cut a recess
to mount on the LITE SUPERNOVA2 50mm (2in) jaws. Jaws must be mounted on the chuck
before the woodworm screw
– See diagram. (Some models Woodworm sold separately) .
Open the jawslide and insert the
woodworm screw in the centre hole of the
chuck.
Position the woodworm screw as shown
in illustration.
Note: All 4 flat sides of the woodworm
screw should be in contact with the flat
end of the jawslides.
The woodworm screw is used to secure the wood to
cut either a mortise or tenon
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 600-700RPM
for 6” and larger, or
heavy work pieces
TURNING ON A MORTISE OR TENON
Tenon is where the jaw contracts onto the workpiece to grip. 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 700 RPM FOR THIS OPERATION.
Tenon Diameter (For 50mm Jaws)
Min Diameter Max Diameter
Cylinder 45mm (1 3/4in) 65mm (2 9/16in)
Square 40mm (1 9/16in) 50mm (2in)
Mortise is where the jaw expands into a recess of a workpiece to
grip. This operation is mainly for bowl and platter (Items with
parallel wood grain).
MUST NOT BE USED FOR ANY LONG WORK (OVER 100mm or 4
inches). DO NOT EXCEED 700RPM WITH THIS OPERATION. OUT OF
BALANCE STOCK MUST BE TURNED AT THE SLOWEST SPEED
POSSIBLE.
Recess Mortise Diameter (For 50mm Jaws)
Min Max
50mm (2in) 70mm (2 3/4in)
FORMING A MORTISE OR TENON
Mortise Tenon
Using a NOVA Dovetail Chisel SKU 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 dovetail profile of between
75~80deg with 10mm (25/64in) depth. Using a suitable chisel, turn the outer
diameter of the wood to form the tenon.
The length of the tenon should be 3mm
less than the internal height of the jaws.

ACCURACY
The LITE SUPERNOVA2 Chucks are sample tested from each
batch and are made to run within the following tolerance
limits on the 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.
See trouble shooting guide for detailed guide on accuracy in
the full manual online at
