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/LH 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
  • 2-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.

Excellent choice
My first nova purchase and it’s a good one. I didn’t know the quality I was getting and this item shows why it’s most popular. Easy install and set up, no matter what jaws your using. Solid grip that leaves you sure and positive about the wood holding while turning. Excellent choice and I highly recommend it.

Nova chuck bundle special
Used it several times and very pleased. Used both the small jaws and larger ones.
Stock insertion and jaw tightness are critical for properly balanced turning.

Incidentally, been a woodworker for 60 years, but new to turning.

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.
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.
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?
