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.

turned my bass into a fretless with ease

By

Verified Buyer


I wanted to turn my 5 string bass into a fretless but was afraid of the possibilities of messing up the neck during the sanding process. I found one of your radius sanding blocks to be the perfect fit for my bass' neck. I removed the frets, filled the small imperfections with superglue (which took on the color of the fretboard), then filled the slots with epoxy and sanded it down using various grits from 220 to 600 and it looks phenomenal and plays great. I wouldn't have attempted it if I hadn't found your sanding blocks. Thanks, Dan

Much better

Than the ones from other suppliers. I would pay the few bucks extra and get these. They are the perfect width and feel nice in your hand. The radius is perfect. great for clamping also with a thin piece of plexiglass between the frets and the block.

Such a simple tool that makes life so much easier! Half an hours work and I had the perfect radius on my scratch built neck. Yet again, StewMac supplies the right tool at the right price.

God Bless StewMac!!

I bought 3 imported guitars. They are beautiful wood and paint but the fret boards and pick ups really really suck!! They were all flat necks with no radius. I bought the (12" Radius) 8" sanding block with 120 and 300 sticky paper. Also the medium and wide fret file. All together it cost me a little over a hundred. My guitars all have new pick ups and they have the nicest playing necks I have ever played. They are better than my other guitars with absolutely no buzz and amazing never ending sustain thanks to StewMac. I love playing again! I have to go in my room every couple hours and play them like a little kid with a new Xmas present. I am 49 and Gosh I wish I had known about this 30 years ago! Again Thanks Guys! I feel the 4" block might be very handy too for ramping down from 15th fret to the heel! Cheers!

Robust block of wood with accurate radius. I used it for fret board shaping and fret levelling. Works likes a charm.
