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.

Perfect tool for the task.

Makes neck preparation much easier!

Nice blocks. Please make a 15" for most Taylors

By

Verified Buyer


Most Taylor guitars have a 15" radius so it would be great if there was a 15" radius block available here. Still, most common sizes are available and in multiple lengths, so that's great.

These work well. I only have 1 but now I'm going to buy more while they are on sale 20% off.

Easier leveling

By

Verified Buyer


I first bought a set of these awhile back and used one to level a Squier I own.Being my first attempt at leveling,these blocks gave me a the confidence to tackle the job where I was really hesitant to attempt it with a beam,given my inexperience.I recently added the 14" to my set as I have 4 guitars with this radius that all need new frets and I'm getting ready to dive into that.Being that I live in the middle of nowhere,at least 3 hours from the nearest Luthier,I decided to start learning to do my own work,then discovered how much enjoyment I'm getting from that.Stewmac tools and the advice I have gotten from the techs at Stewmac have made this journey go easier,with fewer mistakes.Completely happy with everything I've purchased,as well as with the service.

Needed this for a new guitar

Previously purchased and have used the 12", 14", and 16" diameter blocks and they worked very well, just as expected. They're simple and effective.

The only problem, I should have purchased the longer one!

Not quite 12” radius

By

Verified Buyer


I’m not sure if the guys fabricating these take into account the thickness of sandpaper because the radius is tighter than 12”. This causes the pre-radiused to stick up on the ends. Slightly frustrating.

Always useful

I added a few more essential items to my tool box. Already had a few others but needed this exact radius for a neck rehab project.
