8" Radius Blocks

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.

Great for fret leveling and when used with a shooting board perfect for profiling a radius to a fingerboard blank from flat stock. I only wish they were about a half inch wider.

These are great for leveling and touching up spots. If you want absolute accuracy, go for the aluminum blocks

Multitool!

It's great for nearly anything that's radius related. Use it for leveling frets, as a template for making radius gauges, to hold necks tightly when clamped. Overall great product!

Have you got an annoying problem with those ridiculous Jumbo Frets? Bing boom not anymore you don't. Its just that easy. Pick the correct radius, place your guitar on a level stable surface and support the neck and grind away until those railroad ties are down to a manageable level. Then mask off the board, and polish with steel wool. At least that's what i did with a guitar i got on clearance which had, quite literally, NO - NONE - NADA - 0 fret work at all. I'm not exaggerating. They pressed the frets into the neck and then shipped it out. The ends were like barbed wire and the tops of the frets must have been 3/16" off the board. Now its fine. I'm going to buy every single radius block Stew Mac sells plus all the 4 inch ones too.
