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.

Verified Buyer


I have been purchasing a number of tools to make my hobby of fixing old instruments a bit easier. I have learned that if you are looking for quality results buy quality tools! These sanding blocks are one more example of quality and precision! I love the educational videos too. They have helped me tremendously! Thank you Stewmac for the wonderful tools.

Very handy

Short blocks for quick strokes on the typical smaller number of proud or worn frets. A very handy tool indeed.

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.
