FRET CROWNING / FRET DRESSING TOOL

An easy to use fret dressing tool that is suitable for most sizes of fret wire.

DRESSING THE FRETS

After levelling, the frets should be dressed to reduce the width of the flat/levelled surface over each fret crown. This is essential for good intonation. Our Fret Crowning Tool achieves this by restoring roundness to the frets.

The tool features a unique design that protects the tops of the levelled frets - a precision machined concave profile matches the fret crown and a gap in the tool ensures that pressure on the abrasive is applied to the fret shoulders only.

 

During use, only the shoulders of the fret are rounded. The tool can be rolled to the side when moving back and forth to dress wider frets and heavy levelled areas.

FRET CROWNING ABRASIVE

Emery is the preferred abrasive for finishing and polishing of special metals by engineers and jewellery makers.

A strip of the emery is folded and inserted through the gap in the tool. The abrasive can be trimmed off leaving a neat edge by cutting along the bottom of the tool with some light shears (not included). A small shim is supplied to spread the abrasive.

 

As the abrasive wears, new emery is fed through the tool as required. As a general rule, each new abrasive portion will dress a single fret and two strips of abrasive will be required to complete a guitar.

The tool is suitable for the majority of applications where moderate levelling has been performed. For hard/wide frets some local filing may be necessary before using the tool.

The frets should be levelled before crowning. The photograph below shows crowned frets at the right. The tool makes easy work of rounding the fret ends also.

POLISHING THE FRETS

As the emery becomes smoother the abrasive will polish the fret.

When using the tool, always ensure the fretboard protector is used. This is made from malleable stainless steel and can be easily shaped to the radius of the board. The elastic band can be hooked underneath the end notches so as not to restrict the tool movement.
