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.

This chuck replaces my other non Nova chuck. The Nova chuck runs true and the 3 sets of jaws fit all my mounting applications.
The dovetail feature on all of the jaw sets works extremely well in expansion mode. I would definitely recommend this chuck.

I first received the wrong chuck. I called and another was sent out. I had a little trouble explaining what happened to the CS person but he got it right. I had the chuck on the lathe soon after getting it and turned the first piece on it quite nicely. I'm a 50 year woodworker but new to turning.

Will this chuck work on my excelsior mini lathe?
Tim m on Apr 1, 2018
BEST ANSWER: if the spindle is 1x8tpi. there are no adapters. frankly I don't thing the excelsior mini goes in reverse. my brother has an excelsior MIDI and it doesn't reverse.
will this chuck take an insert adapter (3/4" x 16 tpi spindle)?
Darrell K on Apr 9, 2018
BEST ANSWER: this chuck doesn't receive adapters. it's a dedicated chuck for the nova comet 2 midi.
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

Will this fit my shopsmith mark v?
Dennis b 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.
As a new to bowl turning, what advantage is there for reversing a bowl while turning?
James M on May 11, 2018
BEST ANSWER: good question, son. being able to reverse the turn direction will allow you to do a better sanding job. when you sand, the fibers lay down. when you reverse the turn direction the fibers get sanded in the opposite direction, thus, shearing them off and providing a smoother finish.
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.
does this interchange with a nova 2?
tony s on May 5, 2018
BEST ANSWER: yes. that was the reason I got it. you won't have to get a spindle adapter either, the rev-g3 is a dedicated nova comet 2 midi chuck.
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.
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.
Looking for my 1st chuck. I have a new Jet 1221SP. I'm guessing this would be good for smaller stuff but not sure about a 12" bowl? Any suggestions appreciated.
Brad H on Jul 20, 2019
BEST ANSWER: This would be perfect I have used this on an 18" bowl and actually quite abit out of balance. Plenty of hold and the jaws in this set is a good starting point. I actually have 4 chucks now so that I can just do a quick swap of the whole chuck. when I started I did swap jaws but probably 80% of my turning was with the smaller set, very little with the pen jaws and I only use the larger for really big stuff. I hope this helps. Enjoy turning.
Will this chuck work on a full sized lathe?
Shane C on Oct 10, 2018

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.
I just got a Delta 46-460 and was wondering if I would need an adapter to use this chuck set. I'm brand new at lathe's .. this is my first one .. I've only turned it on to see if it works. It works! Now .. I need a chuck, right?
Gus G on Dec 5, 2019
You don't necessarily need a chuck just yet. The chuck is useful for turning pens and small items. You also use the chuck for turning bowls if you go with the mortise method. I am not sure if the chuck fits your lathe. I could not get enough info on the 46-460. Running the lathe backward would spin the chuck off the unit if it threads on.
is there a set of jaws to grip an inch to inch and a half round blank?
James B on Sep 19, 2019
BEST ANSWER: You could use the small pin set but I don’t think it would work real well. If you are wanting something to drill pen blanks Pen State has a nice four jaw chuck for that purpose.
Will this fit on Rockler’s Excelsior Mini Lathe?
Applewoodie on Feb 20, 2019
BEST ANSWER: As in the Rockler item description, "it can be used on any lathe with a 1" x 8 TPI thread". So yes, it will fit the Excelsior Mini Lathe. The Nova G3 Reversible Chuck is a great product... perfect for mini and midi lathes.
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.
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: well, there is no l/r threading. there is a set screw to lock it down, allowing it to go in reverse w/o giving you an upper cut to the chin. meaning it won't come loose.
Will the pen jaws hold a 3/4” dowel, allowing me to drill a hole through the center of the dowel, end to end?
Debbie H on Sep 8, 2018
BEST ANSWER: The short answer is yes, but the question is wrong. This Nova G3 set comes with 2 inch and 4 inch jaws, plus the pin jaws: Nova item JSPIN, Rockler item 47391. You asked about the pen jaws, which are sold separately and not included in this set. The pen jaws are Nova item 6034, Rockler items 48757 and 61849. The 61849 version is a limited edition, currently on sale. Both the pin jaws (included in this set) and the pen jaws (not included) will hold your 3/4 inch dowels for drilling. I own both, but prefer to use the add-on pen jaws for this type of drilling. I like the pen jaws because you can see when the drill pokes out the back of the dowel as long as you don't mount the dowel too flush to the back of the chuck. For a 3/4 inch dowel, that works fine.
Will this set work with a 'lower end' JET lathe? Is it threaded for use on this lathe?
ricswood on Jan 18, 2020
BEST ANSWER: Hey ricswood! I use it on my jet lathe, great chuck use it almost everyday and haven’t had any issues with it! Make sure you use compressed air to clean it out...
Is there a 75mm Jaw set to go with the Nova G3?
George G on Dec 15, 2019
BEST ANSWER: They make a 70 mm jaw set, Nova 70 mm (2.75'') Jaw Set Item #47450. Next size up is 100 mm. If the 70 mm is too small, depending on what you are turning, perhaps the Cole jaw set, Item #45174 might work.
does anyone make an adapter so this chuck will my 18/36 Laguna lathe ?
Rusty R on Oct 17, 2019
