SUPERNOVA2 CHUCK EXPLODED DRAWING & PARTS LIST ITEM NO. QTY. PART NO.
CHUCK OPERATION Adjustment: A handled chuck pinion key is provided for adjustment of chuck action. Please refer to the exploded drawing on page 6 for location of the two key positions. TO OPERATE JAWS: 2 Insert the Allen key into one of the two 22mm guide holes in the SuperNova body. Ensure the Allen key is sitting firmly into the slot - if not engaged properly tightening power will be reduced and could result in damage to gear teeth.
MOUNTING CHUCK ON LATHE There are two versions of the SuperNova2Chuck: an insert version for all threads up to 27mm (1 1/8”) and threaded versions for dedicated threads up to 38mm (1 1/2”). CORRECT MOUNTING OF CHUCK TO INSERT (WITH INSERT VERSION) AND LATHE SPINDLE IS VERY IMPORTANT TO ACHIEVE ACCURACY. INSERT VERSION: Check that the correct insert has been supplied to match your lathe spindle thread.
damage) and screw in insert using the optional accessory spanner or a 1 1/2” AF spanner. Care needs to be taken that the outer male insert thread is engaged properly at the start with the female body thread. Screw insert fully into body recess. This is important to ensure running. Refer to FIGURE 2. CHUCK INSERT SPANNER: An optional, accessory insert spanner can be purchased to help wind the inserts into the chuck to remove from the lathe spindle. (Code 23014). See back of manual for further information.
MOUNTING JAWS The standard SuperNova2Chuck is provided with either 50mm or 75mm add-on jaws. They need to be located and screwed on to the jaw slides of the chuck. The same procedure outlined below must be followed for all accessory jaws as well. IT IS IMPORTANT TO LOCATE JAWS PROPERLY IN THE JAW SLIDES FOR THE CHUCK TO FUNCTION ACCURATELY. Refer to FIGURE Follow the method set out below 1. You will notice that the back of the jaws have a stepped location ring.
shanks are aligned to the jaw slides and close jaws around it. BEFORE FINAL TIGHTENING MAKE SURE THAT THE FRONT OF THE BOSS SECTION OF THE SCREW IS SEATED BEHIND AND AGAINST THE 50mm JAWS. This will prevent any tendency for the boss section to creep forward when the screw is being used. The front face of the 50mm jaws has been machined to provide an accurate backing surface. This is quite an advantage, providing a much tighter fit and better tolerance for irregular face stock.
For smaller lids and thin platters (not exceeding 150mm diameter) only a shallow recess of around 3mm (1/8 inch) is necessary. It will be a matter of gaining experience as to what combinations and sizes will suit best. FORMING RECESS The jaw dovetail has been designed for use with a standard skew scraper. This chisel will make a recess to the angle required. FOR SAFETY REASONS WE STRONGLY ADVISE AGAINST USING ANY OTHER TOOL. A profile of this chisel is shown opposite.
SPIGOT OPERATION This is where the jaws contract around a wooden spigot for grip. This function is mainly for box, goblet and vase turning, that is, end grain items with a fair degree of overhang. 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. DO NOT EXCEED 850 RPM FOR THIS OPERATION. If used properly the Nova chuck however, provides a very secure grip in this mode.
TROUBLE SHOOTING GUIDE FAULT 1. Insert jams when partially threaded into body REMEDY Check insert thread and chuck body thread are free from damage. Check insert has engaged with chuck body thread correctly. See ‘Fitting to Chuck’ Page 6. Make sure grubscrew has not been SCREWED IN. 2. Chuck body appears not to run true Check insert is property home in chuck body. Check that the insert is correctly screwed onto lathe spindle. Insert must back against accurate face/register or bearing on lathe spindle.
10. Wooden spigot shifts during turning Check that the spigot area is made correctly for jaws to grip. Check that the spigot is not oversize. See spigot operation instructions Page 11. Use careful chisel techniques that do not exert too much pressure Irregular rough wood blanks need to be checked to see whether there is enough jaw contact. 11. Wood blank does not seat properly in internal dovetail mounting Check the angle of the dovetail recess made is the same angle as the jaws.
SuperNova2 Chuck Maintanence This guide covers all steps, beginning from when your chuck is on the lathe; you may wish to skip several steps in order to advance to where you are currently at.
Using a 1½” spanner (like accessory 23014 pictured) undo the insert from the wood lathe.
Screw in any Teknatool insert in the chuck thread. Engage the thread partially and tap on the back of insert with a mallet. You will see that the backing plate starts to come off. Remove the backing plate Now using two flat head screw drivers gently push together to lift both sides of the plastic backing plate evenly. Do not try to force the backing plate out as this may damage the plastic plate. Remove the plastic backing plate completely thus exposing the pinions and back of the scroll ring.
Re-grease the scroll ring and pinions; be very generous with grease application. (Normal multi purpose grease is sufficient) If possible before re-assembling chuck blow out all parts with an air gun, if you do not have this carefully check that all parts are free of particles or debris. 2 Re-assembling the Supernova chuck Jaw slides forming a square in the center Push all jaw slides to meet in center forming a square. Make sure the No.
Showing circlip snapped closed Place the circlip back on using the circlip pliers, you’ll see that once the circlip is in its groove the two ends will snap together, see the above picture, you will notice that there in now only a small space between the two eye pieces of the circlip. YOU MUST WEAR SAFTEY GLASSES WHILE PERFORMING THIS OPERATION AS CIRCLIP MAY FLY UPWARDS OFF PLIERS Using 11/2" spanner to re-attach insert.
