Details

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.

8" Radius-sanding blocks

I Coated the fingerboard on my 2008 Fender fretless Jazz bass with slow drying epoxy. I tried to level the fingerboard with a regular flat block first. It worked, but it wasn't perfect by a long shot. I was ready to take my bass to my (excellent) luthier to finish the leveling job, when I read the reviews on the radius-ed blocks from StuMac. I'm really glad I decided to try it. I was able to do a much more professional leveling job with "the right tool". Now that I have a little experience with epoxy, and getting it leveled properly, I'll be able to do some of my other fretless basses, and also keep them re-coated, and/or touched up occasionally. I'm very pleased with the result. It seems like a lot of money for a piece of wood, but I promise you won't look back. I would definitely recommend these blocks to anyone pro, or amateur. The results are worth the price.

My first use was as a caul to set up a neck on the drill press to drill mounting holes. Looking forward to using it for fret leveling.

It works just like it should. After I level the frets with my leveler I lightly use these to get the frets uniform from end to end.

Great for leveling finger boards and frets. I even used it as a template for pre-bending my fret wire. Nice!

Worked for My First Guitar Build

By

I purchased this item for my first ever guitar build that I am still currently working on. Since I had a pre-cambered and slotted rosewood fretboard, I only used this to level and finish-sand it after gluing it to the neck. It matched the 12" radius of the fretboard and I was pleased with the result. My only concern is the long-term dimensional stability of this product given its wooden construction. I think it will still be good to level my frets, but then I may eventually invest in the aluminum beam for future projects.
