    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.

    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

    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.

    Excellent product, Excellent Quality, Affordable price

    I bought this radius beam with a 14" radius. It is as it is described. Fully aluminum and the radius was precisely machined and matched my radius gauges. The length is 20.5" and the width is 70.05 mm (2.75"). The height will vary depending on the radius, the center is 30.1mm (1.18") and the edge was closer to 30.7 mm (1.21")

    The finish is not smooth on the radius face but it helps to maintain grip on the sandpaper. I use the 3M sticky paper and it fits just right. Packaging was great and well protected. Overall, excellent value, excellent product, I highly recommend!
