    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…

    ALUMINUM RADIUS SANDING BEAM 20.5" (520MM) LENGTH

    Posted by Nick Burns on Sep 1, 2021

    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?

    Great value, fast shipping, much better option than competitors. I researched these for weeks and I am totally sold on the quality of these beams. I will be buying the whole set.

    Awesome

    Posted by Alex on Apr 16, 2021

    when i got my 15 inch aluminum sanding beam i checked the radius and it was a perfect 15 inch radius, then I got out my starrett straight edge and a half a thousand feeler gauge and couldn't slip it under the straight edge any where on the beam , needless to say I was extremely happy , then I got very sad and felt like I got ripped off cause I remembered that I paid about twice as much for the other sanding beam i got from stew mac and it's 2 1/2 INCH longer than theirs , and come to think of it Philadelphias rhynostick abrasive sandpaper is a little cheaper in price than stew mac but you get almost twice as much as stew mac and the quality is way better than there's , but i am not going to kick myself over this , but i am going to kill myself for spending my hard earned money with stew mac , i wish i knew about Philadelphia luthier tools and supplies sooner sincerely alex from spokane washington

    Excellent sanding beam

    Posted by k9taxi on Mar 26, 2021

    These sanding beams are longer and significantly cheaper than the comparable Beef Stew-Mac & cheese sanding beams. The quality is outstanding. I have the 7.25" 12" 14" beams and they are all excellent.
