The sanding tool plates are 75mm wide x 150mm long with rounded ends to match the abrasive disc. When attaching new abrasive, the overlaps at the tool sides can be trimmed at the edges or folded back. The folded sections can be later utilised by rotating the abrasive around.

UNIVERSAL USE - Sand any radius between 7.25" & 20".
To sand a fretboard radius that doesn't correspond to a particular tool plate, a larger radius plate should be selected. The final radius can be achieved by applying extra pressure at each side of the fretboard and comparing progress with a radius gauge.The kit is supplied with 5 interchangeable tool plates for 7.25", 9.5", 12", 15" & 20" radius.

 

In addition to the specified sizes, the spacing of the tool plates - see photo of plates stacked - also allows the kit to create any radius between the range of 7.25” and 20”. 

 

To sand a fretboard radius that doesn't correspond to a plate, the next size tool should be selected. The desired radius is achieved by alternating the pressure at each the side of the fretboard and checking the progress with a radius gauge.
