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.

Lots of uses

I have a collection of these in 4" and 8" lengths in many of the popular radi'. Can't live without them.

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.

Fast and accurate

I think that these ones are the easiest way to fix a uniform radius with great accuracy. I find it a little difficult to achieve a uniform radius from plane wood. I didn't used any of them for compound radius. I wish only that the aluminum beams were cheaper.

As an amateur guitar builder I can't think in a easiest and more precise way to give the curvature to a neck. really nice!

Nicely made

I decided to get one of these as they were cheaper than one of the 16" flat fret leveling bars. The block worked well, I attached double sided tape and cut a piece of wet and dry to the right size. (However in retrospect I should have gotten the flat bar as I now have 2 guitars of different radii that need leveling. My fault, not the products.) For their purpose, these work well.
