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/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.

ARLIE E on Apr 6, 2018

Will this fit my shopsmith mark v?
Dennis on Apr 27, 2018
BEST ANSWER: To the best of my knowledge, Shopsmiths do not have a threaded spindle. The Nova insert model would be better suited as the carry an insert with a 5/8" bore designed for Shopsmith. There is an adapter available from Penn State to convert Shopsmith spindles.
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?
