8" Radius Blocks

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.

Great product. Gets used a lot. Adhesive backed sandpaper goes on and comes off effortlessly.

work pretty good, just wish they would bevel the ends so when you hit a high fret it wouldn't rip the sandpaper

StewMac ALWAYS has the part, quality and a wide assortment of things I need. I needed the 9.5 radius sander and they had it. Worked perfect.

No complaints - a big precisely curved chunk of wood. I haven't seen a need to get the fancy sticky sandpaper - regular stuff and normal sanding block techniques work just fine.

I've purchased a few of these for use during setup jobs. They work like a charm with the self adhesive sand paper and are high quality hard wood.

The 8 inch sanding block made quick work of re-radiusing my own bass neck. Could not be happier with it.
