Posted on June 1, 2021March 6, 2024 by Dale Phillips Bubinga Bubinga by Roger Sperline Originally published as Guild of American Luthiers Data Sheet #268, 1984 and Lutherie Woods and Steel String Guitars, 1998 Bubinga is a hard, heavy wood which may be suitable for instrument backs and sides. It is as dense as Bolivian rosewood (Machaerium scleroxylon) and seems as hard. The piece I have has a beautiful mottle figure and a general tiger-eye sheen. I chose bubinga because it was available locally, relatively inexpensive, and very hard. I’d only made four classical guitars before trying it. All in all, I think I had good luck. Several woods are called bubinga, including Guibourtia demeusei, G. tessmannii, Didelotia africana, Copaifera spp., and Brachystegia spp. All are called African rosewood and are reddish-brown. I don’t know which one I have. Despite having many evenly-spaced coarse pores as red oak has, it has a specific gravity of 0.94. My piece was chosen from many, over half of which had evenly-spaced, generally straight growth rings. It is easy to obtain 8" widths for resawing into guitar backs. What makes a challenge is that the grain interlocks randomly, turning at times over 60° to the direction the tree grew, then turning back. In other words, though the growth rings are smooth and parallel, the runout changes severely from inch to inch. This gives a mottle pattern even in well-quartered slices, and causes some of the pores to penetrate a 3/32" plank. Shellac and varnish go right through some of them.

Our friendship grew from the time I first met him in 1940 until his death twenty-five years later. Aside from our warm personal relationship, he took a great interest in my own work and taught me many things from his own background of fifty years experience as a luthier. Many of these things I would have been years discovering for myself or may never have learned. Herman Weaver, like most luthiers I have known, was also a philosopher, and even this was reflected in his work. He was often unorthodox in his approach to many problems which confront the would-be luthier. While he was a strong supporter of proven traditions, he did not hesitate to experiment and to discard tradition if it was not supported by his own discoveries. Early in our friendship I started asking him about woods for musical instruments, especially violins. He answered my questions as I asked them, but one day he summed it all up in one paragraph when he said, “wood is something you can learn about, but it is almost impossible to teach anyone else except in generalities. The luthier must have an instinct about woods, he must be able to hold it in his hands and hear in his mind the tones it will produce in an instrument. He must sense the texture and the grain and the character of a piece of wood and I do not know how to teach anyone these things.” Become A Member to Continue Reading This Article This article is part of our premium web content offered to Guild members.

Posted on April 11, 2021March 6, 2024 by Dale Phillips African Rosewood African Rosewood by John Jordan Originally published in American Lutherie #9, 1987 and Big Red Book of American Lutherie, Volume One, 2000 See also, South American Rosewood by John Jordan It’s been over a year since my last installment of this series, “South American Rosewood,” and now it’s time to cover African rosewood. At the 1986 GAL convention, I talked to several wood dealers to clarify and verify some of the information presented here. Also, I talked to many luthiers about what important information they felt was missing or incomplete in the first installment. Requests came for more specific lutherie information: How well does it bend? How good a tonewood is it? Does anyone sell back and side sets? In preparing this article, I’ve tried to find people who have built with a particular variety to see how they feel about the wood. Also, in instances where I know of someone that sells back and side sets for guitar, I’ve mentioned them. I was pleasantly surprised to find a few guitars at the convention made from less common varieties of rosewoods, so I go on with some encouragement.

Posted on December 28, 2020March 6, 2024 by Dale Phillips Cutting Michigan Maple Cutting Michigan Maple by Elon Howe Originally published in American Lutherie #37, 1994 In 1983, I had the guts to try to repair my dad’s old fiddle. I reglued it, sanded it, sprayed on a varnish — it looked great. I was later advised that I had spoiled the fiddle by doing the wrong things. Later on, I bought a fiddle kit. It had the wood, a machine cut scroll, four ounces of varnish, and a half-pound of glue. About six months later I turned out my first fiddle and of course it sounded great. Dan Erlewine, who ran a shop north of us at that time, had to admit that it looked pretty fair. He later admitted he was afraid to see what I might turn out because he knew he would have to be honest. He seemed to be relieved that it didn’t look like a shoe box. At first, information was hard to come by. Finally, we found an address for Hammond Ashley. He recommended a book called The Techniques of Violin Making by Harry Wake. I got to meet Harry at the Arizona Violin Makers’ Association Competition in Tucson — he even bought some willow wood from me.

The system of binomial nomenclature is one of the best inventions. It is effective; it is beautiful in its simplicity. A luthier in New York may talk of trees and wood to a luthier in Faroffistan with precision and mutual understanding. Centuries are tied together between us and the many careful observers hundreds of years ago who left good records in aristocratic Latin, when the common vernacular language was considered not to be a sufficient medium for such learning. To know the names of the forms of life is one of the keenest satisfactions; it brings us into relationship with our materials in another facet of our fascinating occupation. Every binomial has meaning; it is uniquely significant. Consider... Become A Member to Continue Reading This Article This article is part of our premium web content offered to Guild members.
