Some dust created by power sanding, sawing, grinding, drilling,
and other construction activities contains chemicals known to the State of California
to cause cancer, birth defects or other reproductive harm. Some examples of these
chemicals are:
• lead from lead-based paints,
• crystalline silica from bricks and cement and other masonry products, and
• arsenic and chromium from chemically-treated lumber.
Your risk from these exposures varies, depending on how often you do this type of work.
To reduce your exposure to these chemicals: work in a well ventilated area, and work with
approved safety equipment, al ways wear NIOSH/OSHA approved, properly fit ting face mask
or res pi ra tor when us ing such tools.

To reduce the risk of injury, turn unit off and disconnect it from power
source before installing and removing accessories, before adjusting or when making
repairs. An accidental start-up can cause injury.
Since accessories other than those offered by Delta have not been tested with
this product, use of such accessories could be hazardous. For safest operation, only Delta
recommended accessories should be used with this product. Teknatool accessories offered
for its NOVA G3 chuck are also approved for this chuck.
To avoid serious personal injury, follow these rules:
• Be sure eye protection which complies with current ANSI standard Z87.1 is worn. We
recommend that a full face shield be used at all times.
• Be sure chuck is properly secured on lathe spindle. Follow mounting instructions for your
lathe for faceplates and other spindle fixtures.
• for safety, do not rotate chuck under power without wood being gripped.
• excessive speed is a serious lathe hazard. Always turn at the slowest speed possible.
• Speed will vary with wood blank size. The larger the blank the slower the speed. Always
follow proper speed guidelines.
• Do not attempt to use the chuck unless the lathe speeds are known, you must strictly
follow the maximum speed limits set out in the operating section of this manual. Do
not exceed them under any circumstances.
• eXAMINe WooD CARefULLy. Only mount wood that is sound, if any cracks, splits, or
weakness is found in wood - do not mount on chuck. Do not mount any wood that is likely to
break up during turning (e.g. rotten or spongy wood). Do not use poorly jointed or laminated
wood.
• Make sure wood is clamped firmly. Follow mounting instructions for different gripping
modes and jaw types. In the expansion mode do not use undue force or jaws may split the
wood.
• Do not exceed maximum guidelines in this manual for wood blank diameters or
lengths set out in this manual for different modes and jaw types.
• Do NoT USe WITH ANy CoPyTURNeR oPeRATIoNS.
• Check wood is securely held in chuck, before operation. Check grip by vigorously
wrenching wood blank back and forth. If any loosening occurs, re-examine holding area
for adequate grip (following mounting guidelines) and any damage to holding area. Rotate
manually to make sure of clearance before switching power on.
•
The jaw slides can extend about 1/4" (6.35 mm) beyond the body of the chuck to give a
wider range of expansion, if required. To reduce the risk of injury, always avoid bodily contact
with the chuck.
• Irregular or out of balance stock needs to be turned at the slowest possible speed
until it is in balance. For use in reverse rotation, make sure chuck is securely locked with
set screw before use. Use only hand held woodturning chisels to shape wood being held in
chuck.
• Use the right chisel for the job and do not force tools. Use safe and commonly approved
chisel techniques. Wherever possible stand to one side of the revolving wood.
• Wear proper clothing. Do not wear any loose clothing, neck ties, gloves, bracelets, rings
or other jewellery that could get caught in moving parts. Wear protective hair covering to
contain long hair.
• Do not operate chuck or lathe while under the influence of drugs, alcohol or any medi-
cation.
• Keep children and visitors away. All children and visitors should be kept a safe distance
from the work area. Make workshop childproof with padlocks, master switches, or by
removing starter keys.
NOTES: Before using the 46-461 Lathe Chuck, read and understand this instruction sheet
and the lathe owner's manual. If you do not have a manual, contact the supplier of your lathe
to obtain one before using the lathe and chuck. User must be professionally trained to use
this chuck. Vocational school courses recommended. As with other chucking methods, an
extremely cautious and sensible approach is necessary. With the 46-461 Lathe Chuck it is not
possible to give exact directions as to the amount of tightening pressure required for work-
holding. Closely follow strict guidelines in this manual for different jaw types on wood blank

ASSeMBLy of MAIN CHUCK BoDy (fIg. 2-3)
The chuck is made to fit a lathe spindle with a 1"- 8 TPI.
NOTE: Check that the chuck thread specification matches the lathe spindle thread you have.
This is important for accuracy. The chuck body must contact an accurate register on lathe,
either a shoulder on a spindle or the bearing face to ensure the chuck will run true. If further
modifications are needed (e.g. spacer) these are the responsibility of the user. A good check is
to see whether it screws home the same as a faceplate or similar spindle fitting.
To assemble the chuck to your lathe:
1. Screw the chuck body (A) to the headstock (or spindle nose).
2. Lock chuck to headstock with set screw (B). Insert set screw at hole (I) and tighten securely.
ASSeMBLy of INCLUDeD 2" (50 mm) CHUCK JAWS (fIg. 1, 4)
Attaching Jaws
1. First, wipe clean all jaw slides (J), especially the contact surfaces.
2. Jaw slides are numbered one to four and have a corresponding jaw (D) of the same number.
This may be represented by dots if numbers are not present. (For example, three dots would
go with the number "3" etc.)
3. Place a jaw on its correct jaw slide and position it into the groove, matching the holes in the
jaw with the holes in the jaw slide. The first few times, you may need to geNTLy tap the jaws
into the locater slot with a block of wood or plastic mallet.
4. Place 6 mm countersunk screws (F) in jaws and screw them to finger tightness. When both
screws are in, tighten fully and then loosen half a turn.
5. Repeat this to the remaining three jaws. Next, using the chuck key (H), scroll all jaws to the
middle until they come together. With all jaws touching and with equal pressure on each, tighten
all screws. This will eliminate any run out.
6. Ensure that there are no gaps between the jaws. (If a gap does appear, it is probably because
a jaw is on its wrong number.)
Removing Jaws
1. Using the 4 mm Allen key supplied, unscrew all 6 mm countersunk screws (there are eight of
them). The jaws will come away once these screws are released.
2. Sometimes due to dust particle build up (after heavy turning) the jaws may need a very light
tap with a plastic hammer to dislodge them.
3. It is important to keep them in their set and not mixed up with other jaws of the same type.
CHUCK oPeRATIoN (fIg. 5)
To open and close jaws, insert chuck key (H) Fig. 5 into hole in chuck body and twist key
clockwise to open jaws and counter-clockwise to close. The jaw slides are equipped with an
auto-stop feature that prevents them from being removed.

ing operations.
Place the boss section (X) of the woodworm screw (G) into the center of the chuck and close
jaws into the slots. Before final tightening make sure that the front of the boss section of the
screw is seated behind and against the 2" (50mm) jaws (Y). This will prevent any tendency
for the boss section to creep forward when the screw is being used. Thread the pre-drilled
workpiece onto the woodworm screw until it is seated firmly against the jaws. Recommended
pre-drill size is 9/32" (7mm) for soft woods and 5/16" (8mm) for hard woods.
NOTE: In Fig. 7, the chuck is shown with one jaw slide removed for clarity only. Do not use
woodworm screw without all four slides in place and tightened securely.
The woodworm screw provides 39/64" (15.5 mm) of thread beyond the jaws. Irregular, rough tree
blanks (e.g. small sections of tree limbs) not exceeding the sizes below can be held quite firmly
but caution must be exercised. Check for adequate contact. Do not use the screw for very large
wood blanks. It is intended for small bowl and screw chucking work. The maximum capacity
which should be mounted on the screw is 10" (250 mm) diameter by 4" (100 mm) depth. Do not
exceed 600 rpm for this operation, and use tailstock with a live center for support.
DO NOT USE this chuck unless it is properly fitted to spindle.
Tighten set screw (B) securely before turning in reverse.
To avoid personal injury, do not use the woodworm screw (G) for reverse turn-
