Posted on January 11, 2010March 7, 2024 by Dale Phillips Review: Acoustics of Wood by Voichita Buchur Review: Acoustics of Wood by Voichita Buchur reviewed by Nicholas Von Robison Originally published in American Lutherie #57, 1999 and Big Red Book of American Lutherie Volume Five, 2008 Acoustics of Wood Voichita Buchur CRC Press, 1995 ISBN 0849348013 Voichita Buchur’s book Acoustics of Wood is a synthesis of over fifty years of work by the scientific community into the physics of how this complex material responds to vibrational wave stimuli. With almost 800 references into the literature and about ten years from inception to its being published in 1995, it is a tremendous resource for the luthier’s understanding of his/her main material. I don’t get the feel from the text that the author is a maker herself, even though she is a member of the Catgut Acoustical Society. The book is heavily weighted towards violin family instruments, but this doesn’t make the book any less valuable to guitar makers. After a short, well written, general discussion on the anatomical structure of wood (macro, micro, and molecular), a brief outline is presented dividing the book into three major sections. Part One explores the physical phenomena associated with the effects of acoustic waves in forests (windbreaks to attenuate noise) and architectural acoustics (concert halls, office buildings, restaurants) with wood being used as a construction material and insulator in conjunction with other nonwood materials. A survey of six European concert halls and their geometrical, acoustical, and construction data is pretty interesting.

Posted on January 11, 2010February 7, 2024 by Dale Phillips In Memoriam: Nicholas Von Robison In Memoriam: Nicholas Von Robison Passed June, 2000 by Tim Olsen Originally published in American Lutherie #63, 2000 and Big Red Book of American Lutherie Volume Six, 2013 How well I remember the first letter we got from Nick. He told of being introduced at a party as a “Master Craftsman.” At first he was flattered, but was quickly brought back to reality when the local birdhouse tinkerer was also identified as a “Master Craftsman.” That was in 1982. Nick and I kept up a lively and voluminous correspondence for the next eighteen years. Nick was a GAL member for twenty-three years. As a kid, Nick was in a rock band with his big brother called The Hatfields, and they actually put out a single in the ’60s. He also did a stint in a hippie combo modeled along the lines of Captain Beefheart’s Magic Band. His later musical taste ran to playing Japanese flutes. He worked as an amateur luthier, and then began the enormous project of singlehandedly building a good-sized wooden sailboat. He had completed a lot of the fittings and had a good start on the hull when a fire at the space he was renting deferred his dream. He often wrote of his plan to sail to Bora Bora and Tahiti. But he did get around. He spent a summer hiking the Pacific Crest Trail, and recently he had discovered sea kayaking. He was an avid fly fisherman and had some articles published in fishing magazines. And remember the big hoo-ha about the Mojave Phone Booth a year or two ago? Nick was the discoverer of the Mojave Phone Booth. It’s a long story, but a well-documented one. Photo by Dale Blindheim. Nick was a GAL True Believer. We published many of his articles over the years, and he served for a time as an Associate Editor of American Lutherie. His academic and practical knowledge of botany and wood anatomy was particularly valuable. He was our go-to guy for all wood identification questions and was the major contributor to our book Lutherie Woods and Steel String Guitars. He had a special commitment to the Guild’s benefit auction, spending hours tending the preview at conventions, as well as donating many items and paying ridiculous prices for others. The Guild owes Nick a particular debt of gratitude for talking me into getting e-mail, then hounding me into agreeing to try out a web page for the Guild. Back in the primitive 14.4k days of 1995, he developed the page, got it up on the web, and proceeded to maintain and improve it for another couple years, all as a volunteer. To date we have had more than 170,000 hits on our page, and half our annual income flows through it. I only saw Nick a few times, at GAL Conventions and once when he came through town on a vacation. Still, he was a close friend. Our correspondence covered everything from God and Man to rock ’n’ roll. They tell me Nick took his own life in the first days of June. I really can’t believe it. It just does not fit with the rest of the story. It seems a lot more like he’s finally off on that long journey to Bora Bora, and some day he’ll tell me all about it. I’m going to think of it that way.

Bruce Hoadley Review: Identifying Wood: Accurate Results With Simple Tools by R. Bruce Hoadley Reviewed by Nicholas Von Robison Originally published in American Lutherie #29, 1992 and Big Red Book of American Lutherie Volume Three, 2004 Identifying Wood: Accurate Results With Simple Tools R. Bruce Hoadley Taunton Press, 1991. 224 pp. ISBN 0-942391-04-7 Can’t tell the difference between... uh... spruce and Shineola? Hope that batch of Picea excelsa you paid a small fortune for really isn’t Pinus attenuata or something similar? In times past, wood identification has been the weak spot in most luthier’s knowledge simply because the ID methods available have not been user-friendly. Dr. Hoadley has made a valiant effort to remedy this problem and I think has succeeded very well in his hybrid approach to wood identification. Of the old methods, one approach involves trying to match an unknown wood with a photograph or a veneer sample. The futility of this approach is obvious unless you are a rank amateur trying to determine whether a sample is walnut or zebrawood. The other method, usually presented in texts for professionals, involves a thorough understanding of wood structure, formation, chemistry, and so on. The ID process is accomplished by the use of dichotomous keys — this type of key presenting a series of choices, each choice involving only two possibilities. While this method can be highly accurate if you know your wood stuff, making a wrong choice or misinterpretation anywhere during the keying process can throw you wildly off the track.
