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.

If you can't afford the aluminum radius block this one is essential and perfect for clamping when gluing on your fret board.

I normally use my aluminium or steel radius blocks but i didn't have a 12" radius block so i bought this just for one custom build. It worked well and i will be keeping this on the shelf until i need it again

Excelente herramienta para trabajos de refret y leveling

By

Ideal para cambios de frets, deja el mango con el radio correspondiente para la inserción de los nuevos trastes, y también para nivelarlos luego de la instalación o simplemente en un proceso de rectificación.

Se puede utilizar con lijas sin necesidad de adherentes.

Totalmente recomendado.

great product, fair price

By

You might think this is an awfully high price for a piece of wood, but it is actually an entirely fair price for a great product. I bought one to try, but then built my own setup to make them. While I made myself a bunch of them in all different sizes, with the tooling, the time involved, and the cost of materials ( hard maple, ) I could not make them and sell them at this price. Add to that inventory and warehousing, and I am amazed StewMac can sell these at this price.

And they really do work very well. Doing a full radius job by sanding is a lot of work. Get some hard maple to practice on before you try an expensive piece of wood. It takes a few tries to get it to come out straight, especially the small radii. Re-radiusing and cleaning-up are much easier. You don't need the adhesive sandpaper, just wrap a 1/3 sheet around the block and hold it with your fingers.

If you want to try your hand at neck-building, this tool is essential. I would recommend the 8" length 12" radius - you can get a lot of mileage out of that, including re-radiusing StewMac's own pre-made fretboards.
