Comment from Charnwwood.

Should I choose the Viper3 or Nexus3 chuck?  The Viper chuck is our original model, it is more compact in size, yet has a larger range of jaw movement. It is compatible with several other brands of chucks and jaws.

The Nexus chuck was designed to give compatibility with another family of chucks which are popular in the UK. If you already have a chuck and some accessories from that family then the Nexus would be the better choice for you.

If you do not currently own a chuck then we consider the Viper to be the better choice.

4 Jaw Scroll Chuck.

Based on our best selling Viper range of chucks, we are now launching the Nexus3 which has a jaw mounting compatible with Supernova, G3 Nova and Robert Sorby Patriot Jaws. This will be of particular interest to any owners of those chucks looking for a second chuck and wanting to be able to continue using any jaws they already own.

A 4″ sized scroll chuck, with the jaws adjusted by a geared mechanism for simple one handed operation. Self centring, high precision design. The fully enclosed body of the chuck prevents dust and chips from getting inside and plugging up the teeth of the gear mechanism. Ideal for Midi sized lathes and upwards.

The standard dovetail jaws can grip the workpiece both internally or externally depending on the style and shape of the piece to be turned.
The chuck fits directly onto lathes with headstock thread size of M33 x 3.5tpi. For other thread sizes, an optional insert is required.

We also include a wood screw which clamps into the centre of the chuck for the initial mounting of bowl blanks.

Supplied with standard dovetail jaws, wood screw, T-bar for locking the jaws and T-handled hex key for swapping the jaws.

We have an extensive range of optional jaws and accessories available for the Nexus3 chuck.

Full range of optional jaws & accessories listed below.

Jaws for the Nexus3 are also compatible with the following chucks:

  • Supernova (Requires N3JS Screws)
