  • Shape a new top nut.

  • Make an acoustic or classical guitar saddle.


The key feature of the vice is its unique comparison of the fretboard crown and nut slot depth. This enables precision work to be performed off the instrument whilst having an accurate reference to work from. For example, the nut files can be used without risk that the headstock will be accidently marked. If extra slot relief is required then this is easier to achieve with no limitations on the filing direction.


The comparison is achieved by a simple arrangement using two sliding plates that are used to gauge the depth of the nut slot relative to the fretboard crown (similar to using a vernier depth gauge). After gauging, the plates are locked together creating the datum comparison. The top of the vice jaws simulate the position of the fretboard crown and the nut seating plate provides the reference for the nut slot depth.


The setup allows the nut to be removed for checks on the guitar then replaced in exactly the same position in the vice every time. The nut is always seated on its underside (datum) and there is no fiddling to adjust the height in the vice.


The nut seating plate has two different ends which can be easily swapped around - a flat end for standard nuts and a curved end for fender style curved bottom nuts.


The vice jaws are narrow providing good access for shaping and filing slots. The tool is designed for use in a bench vice for comfortable working height.
