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 tool

I love these things. I have one of every radius offered by Stew-Mac and use every one of them. I can now do fret level and re-crown jobs in 30 minutes! I would, however, like them to offer one in a 15 inch radius for all the Ibanez guitars I work on.

Appears to be made from hard maple. The block is precision cut. Worked perfectly.

Sanding block

They work good if you know how to use them. Just make sure you check that they're not warped before you start. Like anything made of wood, they can warp in different directions on a weekly basis due to temperature and humidity fluctuation. Just check before use and you're set.

Handy tool

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

not bad

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.

Works great

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.

As expected...

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.

16 radius block

I recently received my 16" block and just finalized my first fretboard planing. Perfect result. One very satisfied customer.

8" Radius Sanding Block

Worked perfectly, hard to imagine trying to get a perfect radius without it.
