4" Radius Blocks

About This Item

Radius wood blocks for spot-leveling frets and fingerboards, just add sandpaper. Short length is great for working on compound radii. They make great fret-gluing cauls, too!

Create an accurate radius quickly and without guesswork.
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.

These 4" blocks are used for spot leveling, and can also be used as a radiused clamping caul when gluing frets. The longer 8" blocks are better for consistent, full-fingerboard radius leveling.

Dimensions: 4" (101.60mm) long x 2-3/4" (69.85mm) wide

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.

Not as good as originals

By

Verified Buyer


I've been buying Stewmac radius blocks since they first offered them. The current versions are not as high quality as the originals, which were perfect. The ones I've purchased recently are smaller in width, have rough radius surfaces with irregular surface blems and are a much lower quality of wood. Even the ends were not cut square. However, I must point out that Stewmac has the best customer service there is, and when I've received a block that just couldn't be used, they hand picked the best block they could find and sent me a replacement free of charge. I just wish their manufacturing was as good.

I use this block to take down the upper frets.."fall off". From 21-24 I have three different radius blocks . This is my fourth... I couldn't do my fret leveling and compund radius leveling without them.

Indispensible Tool

Sometimes you just need a tool that you can't do without. This is one of them. Once I determined that the frets on my guitar kit needed adjustment (and that my fingerboard radius was 12"), I ordered the 4" sanding block. I also ordered the 8" version at the same time. There was no other way for me to "trim" my frets (with a consistent radius) without these blocks. I'm extremely happy with my purchase.

This radius block worked great to get my bridge radius the same as my fretboard radius. Made a big difference.
