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 (T30590, 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.
