This chuck should not be confused with the sea of far eastern copies of more expensive chucks. this is a high-tech, precision engineered chuck designed specifically as an accurate & powerful work holding system for small & intermediate lathes up to about 15” capacity. The light, compact design minimises loads on smaller spindles & bearings & the standardised jaw & insert interface take the same accessory range as the other nova chucks, to deliver you maximum versatility (though some of the larger jaws are recommended for supernova 2 body). Precision machined on cnc machinery, the g 3 is very accurate, with a fast, precise & powerful geared action. built to the same exacting standards as the supernova 2 it also shares many features found on more expensive chucks, such as auto jaw stop, copper composite jaw slides, a newly designed woodworm screw & versatile 50mm jaws as standard. With a one handed, geared handle it is easy & efficient to mount pieces & the 4 jaw system is very forgiving of spigot & recess tolerances, making mounting much easier even for new turners. This version has a threaded body which takes an insert to suit the threads of virtually all lathes on the market so is particularly useful if you have an uncommon thread configuration, or several machines with different threads or may want to upgrade to a machine with different threads at a later date. in this case all that will need changing is the insert.
