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 blocks

I like them. Two things; Rock maple and sell me the length I want. I used them as clamping cauls and they did work although I was not happy that I made a series of dents in the wood. rock maple would be better for clamping. I would like to see them in 12", 16" or any length I need.

Quality & accurate radius blocks. I'm become more confident doing fretting works.

precise radius

The radius blocks are very precise, to make all the radius on the fingerboard, I can make any compound radius I want to. They are also effective as much for the frets as for the fingerboard.

Excellent  sanding blocks

I bought the 9.5 and 12 radius 8" long and I must say that I am surprise how good they are.Very easy to use with the Stikit Gold Paper Self-adhesive Abrasives.

Dual Purpose & Works Great For Both

By Creative Acoustics from Halifax

These are exactly the right tool for the job when you need to level frets or a fretboard. I bought one for that, and it worked beautifully. I bought a second one (same 16" radius) for use in clamping the fretboard to the neck. No configuration of wood blocks will provide the same even clamping pressure. Do yourself a favour. Buy a couple of these and save a lot of headaches in your next glue-up.

I paint mine in different finishes, for easy identification. I also place .020 ABS plastic on the bottoms. This helps to keep them clean and true.
