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.

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. 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/preturned spigots. SPIGOT SIZE SHOULD BE WITHIN CONTRACTING LIMITS AND USE FULL SPIGOT LENGTH OF JAWS, AS DETAILED IN TABLE OVER. 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 FIG 1 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! 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. FIG 2 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). FIG 3 UN-MOUNTING ADD-ON 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. FIG 5 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. FIG 4 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 mechanism (Figure 4). 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.

Follow mounting instructions for your lathe for faceplates and other spindle fixtures. 18.MAKE SURE CHUCK JAWS ARE SECURELY ATTACHED to the chuck by vigorously wrenching each of the four jaws to check they are firmly in place. 19.DO NOT ROTATE CHUCK UNDER POWER WITHOUT WOOD BEING GRIPPED. 20.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. Consult your lathe manual or lathe information plate for speed guidelines. 21.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. 22.DO NOT TURN IN REVERSE. Do not use this chuck for reverse turning operations. Light reverse operations i.e. sanding, polishing are allowed, do not exceed 2000rpm in reverse. 23.EXAMINE WOOD CAREFULLY. ONLY MOUNT WOOD THAT IS SOUND, if any cracks, splits, or weakness is found in wood - DO NOT MOUNT ON CHUCK. 24.DO NOT MOUNT ANY WOOD THAT IS LIKELY TO BREAK UP DURING TURNING (E.G. ROTTEN OR SPONGY WOOD). DO NOT USE POORLY JOINTED/LAMINATED WOOD. 25.IRREGULAR OR OUT OF BALANCE STOCK needs to be turned at the slowest possible speed until it is in balance. 26.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. 27.DO NOT EXCEED MAXIMUM guidelines in this manual for wood blank diameters/length set out in this manual for different modes and jaw types. 28.DO NOT USE WITH ANY COPYTURNER OPERATIONS 29.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. 30.WARNING FOR SAFE OPERATION.
