FRET LEVELLING TOOLS & NOTCHED STRAIGHT EDGES
A versatile precision Fret Leveling Tool with more than one use!.
The tool utilises Emery Corundum - less aggressive than diamond - which has excellent polishing characteristics.
Genuine Emery Corundum is made from crushed Emery Stone - Rich in Blue Corundum/Blue Sapphire. Its composition enables a highly polished finish to be achieved.
Please note that standard Aluminium Oxide Abrasives (often misquoted as emery) will not produce the same lustre of finish as Emery.
Our Fret Levelling Tool has an ergonomic shaped handle with a recess for the thumb at the leading end and an angled back for good control with 2-handed use.
FRET LEVELLING ACCURACY
Tools are 100% inspected for straightness using a precision granite surface table & dial indicator.
PREPARATION & USE
The guitar neck should be set straight before levelling the frets. It is recommended to utilise a Notched Straight Edge for this purpose as this will reference the fretboard surface itself and ensure consistency of the finished fret profiles and playing feel along the board.
The frets should ideally be fully masked to ensure the fingerboard wood is completely protected. Controls and hardware should be protected from dust also. If the guitar has a natural finish or is open grained then extra care should also be taken. All dust should be thoroughly cleaned before removing any masking.
What Fret Levelling Abrasive should I use?
The starting fret levelling abrasive grade will be dependent on the degree of fret wear.
Coarse, Smooth & Fine grades are supplied with the Fret Leveller making it suitable for heavier wear and guitar shop use.
Smooth Abrasive then Fine is recommended for guitarists performing their own guitar setups.
After levelling, the frets will require crowning to achieve a satisfactory playing feel and to optimise intonation.
Replacement fret levelling abrasive can be purchased from the webstore in convenient pre-cut strips. The fret leveller will also accept 25mm standard width roll.
The tool is also useful for detail sanding/flat sanding of wood by incorporating a suitable abrasive.
(Emery itself should not be used directly on wood).
NOTCHED STRAIGHT EDGES
The Guitar Notched Straight Edge accurately checks the neck straightness & fretboard flatness independent of the frets.
The original design ensures that multiple scales are catered for with a single tool.
A removable steady prevents the tool from toppling over, allowing it to remain safely positioned on the neck during setup and adjustments. (The steady can be used with or without strings fitted).
The design of the tool is based on checking the length of the fretboard that is capable of being deflected. The very highest frets are omitted since these are well beyond the heel/neck join and won't be affected by truss rod adjustment or string tension.
The tool has 18 notches and a double dot mark for position reference is provided. The positioning on the neck will vary depending on the scale of the instrument:
The dots are nominally positioned at the 12th fret.
For shorter scales, the dots are placed at the 11th fret and for longer scales the dots are placed at the 13th fret.
There are 4-versions of universal notched straight edge available from the webstore:
Multiple guitar scales accommodated.
Freestanding use (with steady) and conventional use.
SPOT LEVELLING KIT
This set is suitable for local spot levelling when a complete fret level is not essential.
Set comprises of:
2 Precision Spot Levellers 115mm & 70mm long.
Silicon Carbide Abrasive – 6 Grades.
Fret Level Checker.
Slim design permitting single string dressing without affecting adjacent strings.
The strings can remain on the instrument.
Fit the spot leveller underneath the string at the mid position where there is maximum stretch available.
The choice of starting abrasive will be dependent on degree of wear but it is essential to use each stage after this, as skipping any grades will leave abrasions that will be difficult to remove with the finer abrasives.
Finish by using finer abrasive grades and successively longer strokes of the tool as this will erase any marks that have been carried along onto the adjacent frets.
(It is not necessary to raise the strings when working).
There is a small working overlap when moved to an adjacent string ensuring all of the fingerboard is accessible. The leveller sizes have been designed for standard abrasive sheets (280mm x 230mm) to be equally cut without waste.
6 Grades of abrasive paper : Coarse – Ultra Fine, are included with the kit. The rectangular template can be used to divide the sheet up equally and the abrasive will fit either spot leveller depending on which way it is fitted.
A useful Fret Level Checker is included to help identify problem frets.
The levellers are also suitable for fret dressing with the strings removed.
Use the 115mm long tool for the wider fret spacings (up to 12th fret approx) - and the 70mm tool for the remainder.
