FULL GUITAR NUT MAKING JIG - For all fretboard radii and guitar types

A repeatable luthier tool system that simplifies guitar nut making.
 
The unique feature of the jig is the gauging of the nut slot depth. This enables accurate work to be performed away from the guitar using an exact comparison of the instrument. Nut filing and adding string slot relief can be undertaken without restriction from the guitar making string slot adjustments for intonation easier.

COMPENSATED STRING SPACING:
With uniform/equal string spacing, the space in between the strings decreases towards the bass side. This can be quite significant for adjacent roundwound and heavy gauge strings.
 
With compensated spacing, the string spacing is incrementally increased so that the space in-between adjacent strings is similar across the fretboard.
 
To get the best spacing for your guitar, we recommend setting the overall string spacing to the maximum that the guitar will allow. A small increase without encroaching on the fret chamfers is often achievable.
 
This system is accurate and repeatable. The spacing guides and marking saw ensure the strings are accurately positioned along the nut. This avoids any discrepancies with individual hand marking out of each slot and all of the slots are cut in the same setup.
 
STRING SPACING GUIDES & CHARTS
The spacing guides slots are sequentially numbered for easy identification and charts are provided for cross referencing the string spacings available.
 
GUITAR NUT & SADDLE JIG (Included)
The comparison of the guitar is achieved by a simple arrangement similar to using a vernier depth gauge. Two sliding plates are used to gauge the depth of the slot relative to the surface.

After gauging the guitar, the plates are locked together. The top of the jaws provide the reference for the crown and the step is the reference for the nut seating. This setup allows the nut to be removed for checks on the guitar and replaced accurately back onto the jig without fiddling to adjust the height or squareness.

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

Vice Specification:
Jaw Width 75mm
Maximum Nut Thickness 10mm
Minimum Nut Thickness 2.5mm
