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

By duwhtsrite from Grand Jct., CO
(Customer's Reviews) Wednesday, June 15, 2011


I check each with a straightedge along the string line & they have been pretty much always dead-on. Price is reasonable too!

Good but need the option of a longer version

By Todd from Winnipeg Manitoba
(Customer's Reviews) Friday, June 03, 2011


These are great but could have been made longer. If twisting seems to be a concern a couple of reinforcement rods could be inserted. I just can't justify paying for the aluminum version that is 18" long. Being shorter doesn't seem to give you the warm and fuzzy feeling that the whole neck is uniformly covered. going over it again with my ground flat bottom bar that runs the whole length of the neck (added step) seems redundant. Overall good

Wood Radius Block

Great tool - I used this along with self stick sand paper to radius a flat fret board. Took it right down. Really easy to control and gave a nice radius up and down the board. I also used it to clamp the neck down after resetting it. Highly recommended and worked super for me.

Radiused sanding block

(Customer's Reviews) Wednesday, May 11, 2011


I used this block and a 12" radiused blaock to true up my fretboard on my own guitar. This is a great tool, and is a big help when sanding and radiusing the fretboard.

Awesome!!

Wow how did I live without radius sanding blocks before I found this! makes super fast work of leveling frets and fretboards!! Slap on the Stikit Gold paper, which fits perfectly, and you have a combination that can't be beat! Thanks again for an Excellent time saving tool!!

Great tool

(Customer's Reviews) Saturday, April 23, 2011


I love these things. I have one of every radius offered by Stew-Mac and use every one of them. I can now do fret level and re-crown jobs in 30 minutes! I would, however, like them to offer one in a 15 inch radius for all the Ibanez guitars I work on.

Sanding block

(Customer's Reviews) Wednesday, April 13, 2011


They work good if you know how to use them. Just make sure you check that they're not warped before you start. Like anything made of wood, they can warp in different directions on a weekly basis due to temperature and humidity fluctuation. Just check before use and you're set.

Handy tool

Great product. Gets used a lot. Adhesive backed sandpaper goes on and comes off effortlessly.
