Details

Accurately true or change a fingerboard's radius and level frets.
We make these hardwood blocks for use with Stikit Abrasives, to radius a fretboard quickly, accurately and without guesswork.

Shaping fingerboards: use 80 through 220-grit
Leveling frets: use 220 through 400-grit

When working on compound radius fretboards, simply change blocks as you progress along the neck.

Dimensions: 8" (203.20mm) long x 2-3/4" (69.85mm) wide

See our shorter blocks for spot leveling, and for use as clamping cauls when gluing frets.

What's your radius?
Quickly find the curvature of a fingerboard or bridge with a set of radius gauges. Use them frequently to check your work as you smooth or shape a fingerboard or frets: a quick visual check keeps you from accidentally altering the shape—a mistake that's easy to make and hard to fix.

I have a couple of these in different radius and they always work well on used instruments. Especially where the frets need some truing up or just to level them up quickly.

Fretboard Radius-sanding Block is carefuly made product, but wood is soft. I prefer made it from oak. more expenciwe but much better wood: hard and long lived.

Great price, good tool

Great for fret leveling and when used with a shooting board perfect for profiling a radius to a fingerboard blank from flat stock. I only wish they were about a half inch wider.
