8" Radius Blocks

About This Item

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.

Radius Diversity

By

Verified Buyer


Bought the 12 to straighten out a poor fret job on a Les Paul, also found it vey handy in making a new bone saddle for a friends Epiphone. Worked great for shaping the saddle, and the nut.

very accurate radius

These radius blocks are great

By

Verified Buyer


I have now done 4 fret leveling jobs with these with great results, something I would not have tried but for the great tutorials and tools from StewMac. It would be great if they had different radii on each side to save room in the tool box.

It likely is a good tool, but I bought the wrong sized radius block.

By

Verified Buyer


I appears well made and useful for the intended task.

I've been a professional Luthier for over 25 years, I wish we had this tool back when I began my career!

The Stew Mac Radius Blocks make re-surfacing a fretboard fast and accurate! In fact, at the Guitar Services Workshop, we include a full set of Radius Blocks for every student! To do the job right, always start with the best tools!

If you can't afford the aluminum radius block this one is essential and perfect for clamping when gluing on your fret board.

Great in a pinch

By

Verified Buyer


I normally use my aluminium or steel radius blocks but i didn't have a 12" radius block so i bought this just for one custom build. It worked well and i will be keeping this on the shelf until i need it again
