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.

I use it to level my frets. Best decision for fret leveling

By

I use the 12 inch radius block for all my fret leveling needs. Pair it with some sandpaper and it'll level your frets pretty well. Check with a fret rocker to make sure the frets are all leveled after some passes on the frets.

The right tool for the right job!

20" Radius Block had an accurate radius. Using the radius block, refinishing my fretless Warwick Thumb was a piece of cake and easy as pie. The Tigerstripe Ebony fingerboard had very deep grooves from round wound strings from the previous owner. Starting with 120 grit, I sanded just until there were very small divots from the strings. Moved sequentially up in grit to 220, 320, 400, 800, 1000, 1500 and 2000.

Finish came out in a mirror polish and sighting down the neck, there were no waves or signs of the previous round wound wear. I put some lemon oil on the fingerboard, let it sit for an hour and wiped off the excess. Sanding time was ~30 minutes, bass was back in service in less than 2 hours.

This is a terrific tool that I highly recommend - even for do it yourselfers!

This radius tool made my job easier. I'm sure I will buy other radius tools in the future, for other projects.

These radius blocks along with a diamond fret file allow this non-professional person/me to do professional quality fret jobs on my own guitars which I have a few. I also use the straight edge with the grooves in it to start with a straight neck before I begin--I am surprised at the results I have been getting, and proud of my own work--it is very satisfying with right tools. Stew Mac is great. Will answer any questions always.
