"Hello, I just wanted to shoot you a message and tell you how amazed I am by the product. I own a vintage repair shop and can cut a "good" nut with my eyes closed. This product allows me to do it faster and more accurate even than when using calipers. GREAT PRODUCT!. I don't know how long it took to produce this entire set up but let me say thank you for your time and effort" Ben L. Brooklyn, USA.

“When I got the jig, the quality of the product had already awed me and the feeling only got way better when I used it. Truly, an epitome of the Japanese word "pokayoke" which means mistake-proofing! " Jonathan B. The Philippines.

UNI-JIG GUITAR NUT PROFILING /STRING SPACING SYSTEM

The system comprises of 5 main components.

1) UNI-JIG Guitar Nut & Saddle Vice.

2) Nut Top Profile Template.

3) String Action Template.

4) Proportional String Spacing Guide.

5) Wire Gauges for Fine Adjustment.

A unique feature of this system is its ability to replicate the exact fingerboard nut slot depth and fingerboard radius. This allows nut shaping, string spacing and nut filing to be accurately performed off the instrument. Anybody struggling with close vision problems or neck ache as a result of poor posture will certainly benefit from using this tool!.

UNI-JIG GUITAR NUT & SADDLE VICE

The central component of the jig is the UNI-JIG Guitar Nut & Saddle Vice (shown below). This is a useful tool in its own right and is also available for purchase separately.

JIG OPTIONS

Three jig versions dependent on fingerboard radii required are available in this listing:

1) 7.25", 9.5", 10", 12", 14", 16", 17", 20", Flat.
2) 9.5", 12", 15".
3) 7.25", 9.5", 10", 12", 14", 16".

GAUGING THE NUT SLOT DEPTH

The jig incorporates two sliding reference plates. The plates are used to make a comparison of the instrument by gauging the bottom of the nut slot (similar to using a vernier depth gauge). This creates a step in the jig identical to the guitars nut slot depth.

The plates are then locked together when the comparison has been made.

NUT TOP PROFILE TEMPLATE SET UP

The Nut Top Profile Template is used as a guide to shaping the top face of the nut. Spacing washers (included) are fitted at the lower stud to keep the profile plate parallel in the jig.

For thicker nuts the clamp jaw can be fitted over the profile plate for extra rigidity.

SHAPING THE TOP PROFILE

The top of the nut is shaped to the template profile.

The nut profile template is designed to leave approx 0.5mm (0.020") stock material for nut filing at the treble side, and 1.0mm (0.040") at the bass side. (See photo below - Fitting the String Action Template).

This leaves a minimal amount for nut filing and improves string spacing accuracy as there is less tendency for the files to wander.

As can be seen, the shaped profile is accurate & uniform.

MARKING THE STRING SLOT POSITIONS

The semi-finished nut should be placed on the instrument and the outer string positions marked on the top.

FITTING THE STRING ACTION TEMPLATE

The Nut Profile Template is removed from the vice and the string action template fitted.

Note - the top face of the nut (shaped when using the Nut Profile Template) which increases in height from 0.5mm at the RH side (Treble) to 1.0mm at the LH side (Bass).

PROPORTIONAL STRING SPACING GUIDE

The Proportional String Spacing Guide ensures precise string positioning and optimised spacing.

The slots are proportionally spaced allowing for a progressive increase in adjacent string gauges from treble to bass.

The guide slots are numbered and diagrams are provided for easy reference.

The String Spacing Guide is fitted and adjusted left or right until the desired string spacing is found.

The string positions should be marked on the nut using the saw provided. The String Spacing Guide is designed with an arc/radius of movement. This is to aid contact of the marking saw with the top of the curved nut i.e. to avoid cutting at a slant and to keep the saw central in the slot.

Note the slight progressive increase in adjacent string positions for a 6-string Bass Guitar with 42.1mm overall string centres - from highest to lowest indicated by the rule in the photo below.

Moving the string spacing guide 1-pitch to the right in the photo would reduce the overall centres to 41.4mm, and moving 1-pitch to the left would increase this to 42.9 centres.

(Graduated rule not included).

The string spacing guide is removed after marking the string positions.

FILING THE STRING SLOTS

Each slot can now be filed with the correct size nut file to the top of the string action template.

Relief & action can all be fine tuned in the jig with occasional reference to the instrument.

The nominal action achieved using the jig before any final adjustment on the guitar will be approx 0.5mm (0.020"). This is dependent on several factors including the fret thickness, string gauge and also the bend radius of the strings over the nut).

FINE ADJUSTMENT OF STRING HEIGHT:

This is achieved by raising the height of the nut in the jig, whereby the slots can be accurately filed to an increased depth - see procedure below.

(Fine adjustment can still be made to each slot with the nut fitted on the instrument if this is preferred).

PROCEDURE FOR FINE ADJUSTMENT OF STRING HEIGHT USING THE JIG:

1) With the nut placed on the instrument, tension the strings and measure the action at the 1st fret.

2) Determine the adjustment amount and corresponding wire gauge value.

3) Re-fit the nut to the jig - (with the wire gauge inserted underneath as per photo) - and adjust the slots to the new depth.

Four colour coded wire gauges are included. These are spaced in 0.004” / 0.1mm increments:

0.012” / 0.3mm

0.016” / 0.4mm

0.020” / 0.5mm

0.024” / 0.6mm

STRING CENTRES OBTAINABLE:

6-String Guitar: 34.6 to 44.4mm (15 increments)
Important! This version of the jig is designed for the majority of 6 string guitars. Please check that the centre distances will be suitable for your instrument. An extended version of the spacing guide is available for instruments outside the ranges above - please enquire for further details.

12 STRING INSTRUMENTS

12 string slot configurations can be achieved by allowing approx 2.5mm extra for the outer string position at the bass side when marking out. After marking the 1st group of six slots, the guide is then moved along to the next pitch (increased overall 'E' to 'E' on the guide) and positioned to mark the 2^ndgroup of six with an initial spacing of 2mm at high 'E'. Each paired spacing width will then increase proportionally up to low 'E'. (Approx 2.0mm to 2.5mm).

Dependent on range selected and gauge of strings used, some minor adjustment of individual positions may be necessary.

“My very first attempt at making a nut came out perfect and it was for a 12-string so there was lots of room for error but the jig worked perfectly”. Heath J., Utah USA.

“AWESOME TOOL!!! “Dmitriy O., Irkutsk, Russian Federation.

"I read the instructions, did a practice run, and then made the actual nut. The string spacing was perfect, no guesswork, no measuring involved. It was such a simple task to undertake. Thank you for perfecting such a fantastic Jig". Wayne T, New South Wales, Australia.
