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.

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!

Excellent!

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

Spend $16! It's worth it!

All of the trouble and work to make my own radius block that only gave me ok results. This block is worth saving time and energy making your own. Good shop investment. Will buy more as different radii are needed. Feels comfortable in your hand as well.

Indespensable!

Perfect for leveling fretboards, changing the radius of a fretboard, or creating a radius from a flat fretboard blank. These can even be used to clamp frets down while fretting.

Must have

This is a must have in your shop. In combination with the 3M stikit, You know your fretboard will have the right radius throughout

Pressing blocks

By Tiunov (22) from Moscow, Russia
(Customer's Reviews) Monday, January 23, 2012


Although I never used them for sanding (I prefer straight block), these blocks are perfect tools for installing frets with epoxy. Just use some padding (i make it from thick sheet of polyethylene), and press frets with radius blocks. All my necks are slightly multi-radius, so i can use, for example, 12-14-16 blocks to press all frets simultaneously. But if, for some reason, i need to use constant radius, i'm just waiting a little longer with three separate pressings. I will order similar aluminum beams soon.

nice job
