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.

I like this product. It gives a good view of the fret heights from a radius view. We're ordering another radius.

This is the best thing since sandpaper! Got the radius done on two necks in the time it took me to do one with the shorter timber radius block! It sits in your hand perfectly and due to it's weight you don't have to put too much pressure to get the sand paper to do it's job. Another must have tool for the workshop!

I was looking at this tool for long time now. Finally I pulled the trigger, and bought the radius block. Is little pricey, but now my fretboards and frets are perfect.

16inch radius sanding beam

By

This is a quality piece of kit, and has a satisfyingly heavy/solid feel in your hand. The radiused wooden blocks give pretty decent results, but these are a marked improvement. As a previous reviewer quite rightly pointed out, these 18 inch beams are best used in a simple jig, to keep it absolutely parallel to the piece you are sanding. Done this way the results are faultless.

Amazing Tool

By

Makes fretting and leveling a joy. I glue in the fretboard and then progress from 80 grit through 320 grit until I get the perfect radius and thickness. I drill the shallow holes for the pearl dots and glue them in. I level them with the radius block with 220 and 320 grits. I press in SM fret wire with a SM Jaws 2 fret pressing system. I sight down the fretboard and make any adjustments needed with a few hammer taps. I level with the 18ö block with 320 grit until the frets are perfectly level and if IÆve done my job with a good wood sanding and good pressing, the adjustment is minimal. I recrown where needed with a SM diamond crowning fileà400-1000 grit paper and steel wool until the frets and fretboard are buttery smooth and thatÆs it. About 2 hours start to finish and much less opportunity for screw ups. Great solutions from this company.

IN MY TOP TEN

From the looks of the other reviews there's not really much else to be said. Get one (I mean three). Definitely one of the top ten best tools in the Stewmac catalog or anywhere else for that matter. I used one for the first time to radius a hand made one-pc. maple electric guitar neck and level frets. Simply, and perfectly marvelous. Due to the tool's length you don't have to worry, when leveling frets, about sanding too much or too hard in one spot. Just move it back and forth and let the tools own weight do the work. I agree that, as mentioned in another review, that a temporary jig/straightedge can be beneficial to keep tool from moving unevenly side to side - but not totally necessary if your the least bit careful.

Finally bit the bullet and bought the 12 inch radius beam. Although pricey, I will say that it is an outstanding tool and extremely well made. Another example to show that even if expensive, it will be inexpensive in the long run and makes my guitar making easier and more precise.

Really OK!

The sanding beam is a heavy tool thats doing his job. Unfortunately there was a little transport damage. Nothing big, but I think the packing is a little unstable for overseas-shipping for such a delicate instrument.

I've bought some tools now from Stewmac. The overall quality is good but not ecxellent. You get a better quality when you buy in a german DIY store. Honestly, what really wins are the great tool ideas, but the quality aspect is holding me back to buy some other stuff, that I don't need right know.
