Aluminum Radius-sanding Beam

About This Item

Extended length for fast, precise shaping. Create a constant radius on an unfretted fingerboard, or level installed frets with this unique tool for the professional guitar shop.

The 18" long extruded aluminum block is comfortable to hold, and its stiffness and precisely machined radius assure accuracy that's not possible with a wooden block of the same length. We designed this tool for a lifetime of use in the busy shop.

Lifetime durability • Extended length
Fast, accurate fret leveling and fingerboard shaping


Dimensions: 18" long x 2-3/4" wide (457.2mm x 69.85mm)
Seven different radii are available, for popular fretboard shapes.

A great clamping caul for glue-in fret jobs!
"I use aluminum fretboard sanding blocks to hold and clamp the frets in place while the glue dries...A scrap of Neoprene on the bottom of the caul protects the frets from the texture of the machined surface, and serves as a cushion that conforms to the radius a little better, conforming to any slight variations in the fretboard."
Excerpt from Erick Coleman's book Fret Work Step-By-Step

Cut and stick!
3M Stikit Gold Paper Self-adhesive Abrasives are the right width for our leveling and radius sanding tools. Attach 80 through 220-grits for radiusing and leveling the fingerboard, and 220 through 400-grits for leveling the frets.

Works on stainless frets, too!
All of our tools are suitable for use on stainless-steel fretwire, with the exception of our Fret Tang Nippers. Modern stainless-steel fretwire is known to be harder than the traditional nickel-silver blends, but our own shop experience indicates the wire does not cause premature wear of files or sandpapers.

Quality issues

By
(Customer's Reviews)


The first one I received, all the corners were damaged, returned. The second unit had casting pits, returned. The third unit is good, but too expensive for the quality. For the price it shouldn't have any machining marks. I must say that Stewmac was very friendly and honored all the returns with ease, excellent customer service. Overall I just couldn't give anymore than 3 stars because of the quality, but 5 stars customer service!

Must have!

By

Bought my first one. Really impressed. I went with a 12" since that is a majority of the guitars I've been working with. Did one job with it so far. Results were great. I feel it sped up, and made the process of fret level more smooth.

Very well made, but expensive

These are really well made and precise, and you can get a very accutart fretboard radius with little work. I cut down a sanding belt and stick that to the block with double stick tape instead of using the expensive self-adhesive sandpaper.

Fret Leveling Made Easier!!

These heavy duty radiused levelers are excellent. They cost a lot, but you should definitely get many years of use out of the them without warping.

Precise tool

By
(Customer's Reviews)


I have been kicking around the idea of buying one of these for nearly 3 years now and just couldn't wrap my head around the price. But finally I tried it and bought one. The foot of this tool is cut spot on precise, with a perfect and consistent radius, the edges are straight and it does feel comfortable to hold. It's not as heavy as I thought it'd be based on other reviews but is definitely solidly built. As the saying goes, buy nice or buy twice... This is the nicest tool available on the US market today for guitar fretboard shaping. It will very likely last for decades if properly handled and not dropped and still be as straight as the day I received it. Only reason I gave it 4 stars is because there is an improvement I think could have been made. The bottom surface of the tool has fine grooves in it left over from the milling process, I could see that being problematic with buildup of gunk from sandpaper adhesive which would need to be cleaned regularly between changing sandpaper with naphtha or some other solvent. If the bottom were precision ground and polished as well it would be solid 5 star. Thats only a minor concern, this is still a great tool and will have its own place on the wall to hang in my shop. I am very happy with the purchase and will likely order another radius in the future.

Perfect tool, painful price

By
(Customer's Reviews)


They may be overpriced but these are still really nice. Use them for sanding radius, pressing frets, and gluing fretboards. But good grief, they are expensive.

Absolutely essential tool!!!

By
(Customer's Reviews)


I love this thing!!! I make fretboards, glue the fretboard on, level the frets and use it to remove fretboards on necks I'm not happy with! It is one heck of a workout to radius a fretboard with and if I ever find an easier way to do it that's just as accurate I'll do it but for now this thing does the job perfectly! Customers really appreciate the hard work that goes into making a fretboard with these things and it actually helps sales.

EXCELLENT PRODUCT

By

These make all the diff in the world when you are trying to get a perfectly flat fingerbrd before fretting. If you use Gold Evo or Stainless Steel fretwire, as I do, or evn if u don't, leveling and recrowning ruins a perfect crown u'll never get back. When u start w a flat fingerbrd and use good technique installing the frets U won't need to level and recrown every fret. I generally just have a few high spots on the frets. I dress these w 2K paper on a fret file. I never touch 90% of the frets since i got these. BUY NOW!!!!
