    9.5" Aluminum Radius Beam

    Posted by John Dopita on Jun 5, 2024

    As projects require, I pick up a specific radius beam. Just received the 9.5"R beam. I honestly think the quality is getting better on these beams. The older beams are great, no issue, but the new 9.5 beam seems to have a better finish overall. I'll order another beam as a different radius project comes along.

    Excellent Radius Sanding Beam

    Posted by Dael Bartlett on Jan 2, 2022

    I have two of these, 9.5" and 12" radius, They are a must for prepping fingerboards for re-fret, leveling inlays or binding. I plan to get a 16" next and that will cover most of the guitars I regularly work on. The last re-fret I did using the 12" beam, required very little work on the final frets, in fact (a first) I did not have to level and re-crown the Jesco Gold frets. Totally worth the money.

    Alu Sanding Beam

    I love these sanding beams. Extremely accurate radius and perfectly flat lengthwise, and a couple inches longer than the other guy's sanding beam...which is really great. Better price too.

    Great buy

    I’ve gotten the 10” and 15” radius of these. Both absolutely perfect. If you have to radius a fretboard by hand these are the ones you want. Weight and length makes it go much faster and the radius is as accurate as you can get. Big plus is the are much cheaper than those other guys…

    Very happy with my purchase. An excellent product with a substantial weight that allowed me to sand a radius onto the fingerboard more consistently and in less time. Also, half the price of the bigger named competitor. What's not to love?
