The Viper3 chuck is the best selling size from the Charnwood Viper range. A 4″ sized scroll chuck, with the jaws adjusted by a geared mechanism for simple one handed operation. Self centring, high precision design. Ideal for Midi sized lathes and upwards. The fully enclosed design prevents the build up of chips and dust inside the gear mechanism.
The chuck fits directly onto lathes with headstock thread size M33x3.5tpi. for all other sizes an optional insert is required.
For lathes with reverse direction, locking screws allow the chuck to be locked onto the lathe spindle, providing the lathe conforms to DIN800 or T38 design. Reverse direction should only be used when the chuck is mounted directly onto an M33 x 3.5 spindle thread. It should not be used in reverse when using a thread adapter.
The standard dovetail jaws can grip the work piece both internally or externally depending on the style and shape of the piece to be turned.
Pin jaws allow smaller pieces to held than the standard jaws. The inside is smooth and parallel, the outside is serrated for maximum grip.
The Stepped jaws have a serrated edge both internally and externally. They give great flexibility by combining standard sized jaws and pin jaws.
The Wide jaws have a serrated edge both internally and externally and can grip much larger pieces than the standard jaws.
The Face Plate ring has a 75mm outside diameter and has a dovetail shaped inside which can be gripped by using the standard Viper3 jaws.
The Drive Centre allows spindles to be turned without removing your chuck from the lathe.
We also include a wood screw which clamps into the centre of the chuck for the initial mounting of bowl blanks.
T-Handle square drive for locking the jaws.
T-handled hex key for swapping the jaws.
The storage case has a foam liner to keep your chuck and all the accessories safe and ready to use.
