Nova 30th Anniversary G3 Reversible Chuck Bundle with 3 Jaw Sets and Case

Offering solid construction, minimal vibration and ease-of-use, the Nova G3 has become a favorite chuck for small and mid-sized lathes. It is offered here in a value package with two extra sets of jaws—4'' jaws and pin jaws—in addition to the standard 2'' jaws. Though designed for the Nova Comet II Midi Lathe (#46457, sold separately), it can be used on any lathe with a 1'' x 8 TPI thread. When used on non-reversing lathes, the set screw must be removed. The G3 is a self-centering chuck, so all four jaws close at the same time by turning a single key. With only one hand needed to close the chuck, your other hand is free to align the stock. At just 1.79'' long, the compact G3 helps to maximize your distance between centers, and reduces stress on the spindle. This is not an insert style chuck. Cannot use an insert/adapter to change the threading.


  • Small, compact design minimizes load on small spindles and bearings
  • Dedicated 1'' x 8 TPI RH thread—no separate insert required
  • Designed for the Nova Comet II Midi Lathe, but can be used on any lathe with a 1'' x 8 TPI thread
  • Single-handed operation with included chuck key
  • Four jaw design firmly grips both round and square wood—geared action provides a powerful positive grip
  • Locking set screw allows it to be used for sanding in reverse mode when mounted on the Nova Comet II
  • Wide range of available accessory jaws (Note that although all Nova jaws will fit, not all are recommended for use with the G3)
  • Jaw slides made from high-tech copper fused steel for maximum hardness, wear, and self-lubricating properties
  • Auto safety stop feature—jaw slides can't protrude past the chuck body
  • Precision machined in one operation from a solid steel block for optimal accuracy
  • Polished finish to allow for closer tolerances and accuracy
  • Safe Lock™ Woodworm screw included for fast mounting of rough timbers
  • 6 Year warranty

Package includes two extra sets of jaws—ideal for bowl and spigot turnings—plus a storage case!

The included JS100N 4'' Jaw Set is designed for expanded dovetail or reverse dovetail use. Ideal for gripping footed bowls and mounting custom wooden jaws. The included PSPIN extended pin jaws expand into a pre-bored hole, especially useful for bowls with a free form edge. The long jaw length allows for a powerful spigot grip for work up to 6'' in length. Dovetail allows mounting small bowls up to 6'' in diameter. Both grip firmly in both contraction and expansion mode.

  • Only use authentic Nova accessories on your Nova chuck. Using non-genuine Nova accessories and copies of accessories could lead to operation and safety issues and will void the warranty. Nova accessories are designed for use only on Nova chucks. Do not use on any other chuck.

an excellent chuck
I have a variety of chuck sizes....honestly, I don't like changing the jaw sets (I'd rather be turning), but if you are limited in the number of chucks, this is a great single chuck or addition. The Nova G3 works very well with my Delta midi lathe and it is very solid.

A Great Chuck
I am new at lathe work, but I really like the Nova Chuck. I have watched videos on ways to use it. It took some time to find the right attachment for my Shop Smith. It secures the project much better than the old style center chucks. I made a box out of mulberry, and the Chuck was very helpful. I am now working on my lathe gouges.

Looking to purchase a chuck- this seems like a good deal for a full kit. Excited to try this out!!!
Jason C on Feb 1, 2019
Excellent value for the price. I compared to several other woodworking suppliers and found that Rockler had the best price. Of course, that was before I was charged $16 for shipping. Oh well, I just chalked it up to supporting smaller businesses.
G S on Jan 30, 2019
I already own a Nova G3 chuck with 2" jaws and find it to be a good quality chuck. I needed smaller and larger jaws and this seemed like a good deal. The two sets of jaws would of cost me over $100 alone. Plus with two chucks, I'll save a lot of set up time when I want to turn different sizes.

It’s a luxury to have a second chuck. But a necessity if you turn segmented bowls.

Have a G3 chuck with 50 mm jaws but need smaller and larger and the extra chuck will reduce my setup time when switching over.

Will this chuck work on my excelsior mini lathe?
Tim m on Apr 1, 2018
BEST ANSWER: Yes, this chuck and Excelsior lathe both have a 1" x 8 TPI thread.
will this chuck take an insert adapter (3/4" x 16 tpi spindle)?
Darrell K on Apr 9, 2018
BEST ANSWER: Yes, but Nova does not carry one. They are available from other sources.
Does this chuck set work and work well on a Jet 1221 VS lathe?
Glenn H on Apr 16, 2018
BEST ANSWER: it can be used with the Jet 1221 VS Lathe in forward, however the set screw that makes the chuck work in reversible mode will come down right on the top of a thread and may cause damage to the threads on the headstock
Rockwell lathe has a 7/8 X 13tpi spindle. Would an ifadapter be available to use the G3 chuck?

I have a 12" × 26" central machinery wood lathe with reversable head will the nova chuck work on this lathe?
ARLIE E on Apr 6, 2018
BEST ANSWER: Worked perfect on my central machinery. Zero issues here. So yes it will work. You should have 1"x 8 tpi same as mine. You will not regret buying this chuck set. If you do not have reverse you will have to remove the set screw.
Will it fit on my Ohio forge wood lathe?
Jeff S on Apr 12, 2018
BEST ANSWER: This chuck will fit a lathe that has a 1" 8TPI head stock thread.
does this interchange with a nova 2?
tony s on May 5, 2018
Do you still need to purchase a face plate? Or does this cover what a faveplace does as well?
Landon B on Feb 1, 2019
BEST ANSWER: The chuck will be very helpful for most situations, but if you are turning something very large, such as a wide platter or awkward size, a faceplate can be very helpful as it is more secure. Then as you shape one side, you can switch to the church after turning a tenon or recess. So the chuck does not replace the faceplate; they augment each other.
Will this chuck work on a full sized lathe?
Shane C on Oct 10, 2018
BEST ANSWER: I'm using it on an old Craftsman that is full size, although not industrial
Will this fit my shopsmith mark v?
Dennis on Apr 27, 2018
BEST ANSWER: This was a confusing issue for me, and took me a bit of time to research, so I hope this helps someone else who owns a Shopsmith.

The Shopsmith Mark V has a 5/8" non-threaded spindle that uses a set screw to lock tools in place. Therefore you need an adapter to use NOVA G3 chucks on your Shopsmith.

NOVA, confusingly, makes two different versions of it's G3 Chuck. (An explanation of the differences can be found in the FAW on the NOVA web site).

For the G3 Reversible Version Chuck (NOVA 48232) that comes in this 30th Anniversary G3 Kit you'll have to go to a 3rd party to get an adapter that connects the Shopsmith's 5/8" spindle to the chuck's 1" x 8 TPI threads. As Dennis mentioned above, Penn State makes just such an adapter, the PSI L5818. Hurricane Turning Tools also makes one. I don't think Rockler has an adapter such as this.

NOVA also makes another version of the G3, that is NOT available in a 30th Anniversary Kit. They call it the Insert Version G3 Chuck (NOVA 48202). This version of the chuck has 1 1/2" x 8 TPI threads. NOVA does make an adapter for the Insert G3 Chuck (NOVA ISNS 71029). Rocker carries an adapter like this (Nova Insert/Adapter, 5/8" Plain Bore, Rockler Item # 43743), but it will ONLY work with the Insert version of the G3 Chuck, NOT the Reversible G3 Chuck found in the 30th Anniversary Kit.
I have an old Craftsman lathe (model 113.228160). What adapter would I need for this Nova chuck to work?
David M on Jan 30, 2019
BEST ANSWER: Sorry I was incorrect about what you have on your lathe. It should be 3/4"-16tpi When you measure to verify. when you measure the pitch on the thread , top of one thread to the next. It will be 1/16th of an inch or .062. If that is what is on your lathe then you need Lathe Threaded Spindle Adapter Bushing 3/4-16 to 1-8 To Mount Chucks To Spindles. I could not find it on Rockler's site. It is available on other sites if you google the it.
How do I determine if my lathe has a 1" x 8 TPI thread?
Frank D on Nov 26, 2018
BEST ANSWER: It most owner/operator manuals it will state what the spindle nose is on your lathe. If you don't have the manual, Most of them can be found on line with the manufactures name and model number in a goggle search. Last you can go to your machine and measure the diameter of the spindle. Best done with a pair of calipers. Taking care to be on top of the threads. The 1 inch is a theoretical diameter. There are tolerances that allow that diameter to vary. It should fall between 0.9980 / 0.9830" Then to find the pitch on a thread that is 8 threads per inch, often designated TPI. Lay a rule across the top of the threads. The points or top of the threads will be .125 or 1/8 of an inch apart. For other TPI of imperial designated threads. You simply divide 1 by the number of threads. That will inform you of the distance each thread should be at the top of the thread. That distance needs to be measured on the center line of the thread for accuracy.
will this work on a 3240 WEN?
adam G on Sep 4, 2018
BEST ANSWER: Did you transpose the model number? do you have a 3420? The 3420 has a 1'-8tpi spindle. This chuck is also threaded for 1"-8tpi. if you do have a different model. refer to your owners manual. Iy will provide you with this type of inforamation. You will also want to check on the morse taper of both the tail stock and the head stock. When you buy live centers and drill chucks. Or any other accessory that slide into those areas. If you do have the 3420. It has Morse taper 1 designated often as just MT1.
As a new to bowl turning, what advantage is there for reversing a bowl while turning?
James M on May 11, 2018
BEST ANSWER: The only real advantage for me has been sanding and finishing, no real advantage during the turning process. Happy turning and be safe.
what country is it made?
wooddoc on Jan 25, 2019
BEST ANSWER: This item is made in China
will this fit my Central Machine 40"x14" wood turning lathe model 67690?
Richard A on Nov 8, 2018
BEST ANSWER: I believe that your lathe has a 1" x 8 TPI thread pattern, which this Chuck will fit.
Does the chuck actually have a dual Right Hand/Left Hand thread? I need a Left Hand thread for the outboard side of my lathe/spindle.
Travis F on Sep 30, 2018
BEST ANSWER: I don’t believe so. You can choose which one you are getting though. And then I had to buy an adapter for my lathe to work with this chuck.
Will the pen jaws hold a 3/4” dowel, allowing me to drill a hole through the center of the dowel, end to end?
