SAFETY GUIDELINE – DEFINITIONS

It is important for you to read and understand this manual. The information it contains relates to protecting YOUR SAFETY and PREVENTING PROBLEMS. The symbols below are used to help you recognize this information.
DANGER: Indicates an imminently hazardous situation which, if not avoided, will result in death or serious injury.
WARNING: Indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury.
CAUTION: Indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate injury.
CAUTION: Used without the safety alert symbol indicates potentially hazardous situation which, if not avoided, may result in property damage.
WARNING: Dust created by power sanding, sawing, grinding, drilling, and other construction activities may contain chemicals known to the state of California to cause cancer, birth defects or other reproductive harm. Some examples are:

• Lead from lead-based paints
• Crystalline silica from bricks and cement and other masonry products
• Asbestos dust
• 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, such as dust masks that are specifically designed to filter out microscopic particles. Avoid prolonged contact with dust from power sanding, sawing, grinding, drilling, and other construction activities. Wear protective clothing and wash exposed areas with soap and water.

SPECIFIC SAFETY RULES

WARNING: 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.
WARNING: Since accessories other than those offered by DELTA® have no 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 NOVAG 3 chuck are also approved for this chuck.
WARNING: To avoid serious personal injury, follow these rules:

• Be sure eye protection which complies with current ANSI standard Z87.1 is worn. Werecommend 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.
• When turning in reverse, care should be taken not to stall the workpiece. If a stall should occur, verify that the chuck is fully seated and both set screws are tight before continuing.
• 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 medication.
• 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 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 workholding. Closely follow strict guidelines in this manual for different jaw types on wood blank diameters and length, plus turning speed.

CONTENTS (FIG. 1)

A. Chuck body
B. M6 x 1 set screws (2)
C. T-handle hex wrench (for set screws)
D. 2″ (50 mm) chuck jaws (4)
E. 4 mm hex wrench (for countersunk screws)
F. 6mm countersunk screws (8)
G. Woodworm screw
H. Chuck key
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.
WARNING: DO NOT USE this chuck unless it is properly fitted to spindle.
WARNING: Tighten both set screws (B) securely before turning in reverse.
To assemble the chuck to your lathe:

1. Screw the chuck body (A) to the headstock (or spindle nose).
2. The last 1 to 2 turns, spin the chuck sharply so that it jams firmly against the spindle shoulder.
3. Lock chuck to headstock with two set screws (B). Insert one set screw at hole (I) and tightensecurely. Insert the second set screw in hole (not shown) 180 degrees from hole (I).

ASSEMBLY OF INCLUDED 2″ (50MM) 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 4mm Allen key supplied, unscrew all 6mm 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 counter-clockwise to open and clockwise to close. The jaw slides are equipped with an auto-stop feature that prevents them from being removed.
USING THE WOOD WORM SCREW (FIG. 6, 7)
To avoid personal injury, do not use the woodworm screw (G) for reverse turning 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. A28570 – 09-12-08![DELTA Reversible Woodturning Chuck

• fig 2](https://manuals.plus/wp-content/uploads/2023/02/DELTA-Reversible- Woodturning-Chuck-fig-2.png)The woodworm screw provides 39/64″ (15.5mm) of thread beyond the jaws. Irregular,roughtree 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″ (250mm) diameter by 4″ (100mm) depth. Do not exceed 600 rpm for this operation, and use tail stock with a live center for support.

DOVETAIL OPERATION

(EXPANSION OF JAWS INTO A RECESS)
WARNING: Make sure the jaws are fully seated in the workpiece recess. If the workpiece is not riding correctly, it could dislodge from the chuck. Loosen jaws and remount correctly.
This function is for bowl and platter turning where the projection (depth) of the wood blank is less than 4″ (100mm). If used on longer wood, there is a great danger of wood tearing out and dislodging from chuck.
Using the standard 2″ (50mm) jaws can help turn bowls up to 12″ (310mm) in diameter. (Consult specific instructions included for any other jaw set.) Do not exceed 600 RPM with this operation. Out of balance stock must be turned at the slowest speed possible.
Any recess can be turned between 2″ (50mm) and 2-3/4″ (70mm) in diameter. For smaller lids and thin platters (not exceeding 6″ (150mm) in diameter) only a shallow recess of around 1/8″ (3mm) is necessary. It will be a matter of gaining experience as to what combinations and sizes will best suit this operation.

SPIGOT OPERATION

(CONTRACTION OF JAWS AROUND A WOODEN SPIGOT)

WARNING: TO AVOID INJURY, Do not exceed 850 RPM for this operation.
This function is useful for box, goblet and vase turning, that is, end grain items with a fair degree of overhang. The instructions here apply to the supplied 2″ (50mm) jaws but the general spigot technique is the same for other jaw types.
NOTE: Maximum turning speed and spigot size varies with different jaw types. Consult accessory jaw manual or instruction sheets. USE ONLY JAW SETS approved for use with this chuck.
With the supplied set of 2″ (50mm) jaws a maximum workpiece size of 4″ (100mm) diameter (NOT spigot size) by 6″ (150mm) length can be turned. Also, square timber can be turned of the same length and between 1-1/2″ (40mm) to 2″ (50mm) with the grip of all four jaws into the wood. MAKE SURE you have an adequate grip before operation by vigorously wrenching the workpiece mounted on the chuck. If any loosening occurs, DO NOT PROCEED with operation. Repeat tightening procedure and re-test grip.
SPIGOT SIZE: The supplied jaws will grip a round spigot between 1-13/16″ (45mm) to 2-5/16″ (65mm) in diameter or square timber between 1-5/8″ (40mm) to 2″ (50mm) square.
OPERATION WITH JAW SLIDES ONLY (FIG. 8)
With the 2″ (50mm) add-on jaws removed, the jaw slides will grip either round or square timber down to 3/16″ (4.8mm) and up to 1″ (25.4mm) round or 11/16″ (17mm) square. The length should not exceed 6″ (150mm). Small work not greater than 5/16″ (8mm) diameter can be turned at speeds up to 1800 RPM. Larger work (up to the diameter capacities just mentioned) held in the jaw slides should NOT EXCEED 850 RPM.
