Posted on June 13, 2024May 6, 2025 by Dale Phillips Experimental Violin Acoustics Experimental Violin Acoustics by George Bissinger from his 1984 GAL Convention lecture Originally published in American Lutherie #7, 1986 and Big Red Book of American Lutherie Volume One, 2000 It was a pleasure to discuss the “secrets” of violins at the kind of meeting that would scarcely have seemed possible in the time of the legendary Cremonese luthiers. As a member of the Catgut Acoustical Society, which is devoted to all aspects of bowed string instruments from the raw materials (gut?) to the finished product (cat?) and its sound (meow?), I can only welcome this shared discussion. The Society has sponsored the construction of a family of eight violins covering the frequency range of 41Hz to 1318Hz (lowest to highest open string), and has a demonstrated interest in all violin matters whether they are purely practical, subjective, and aesthetic, or purely abstract, objective, and quantitative. The talk I gave at this GAL meeting covered a range of topics concerning violins in which I personally have been involved. These topics leaned rather more to the concrete aspects of violin making such as working with student instruments, testing plates of unassembled (or humidity disassembled) instruments, plate archings, bassbar tuning, and humidity effects, but also included discussion of coupling between enclosed air oscillations and plate vibrations in the assembled instrument.

Posted on June 6, 2024May 23, 2025 by Dale Phillips Questions: Bracing Reinforcement Questions: Bracing Reinforcement by Jeffrey R. Elliott Originally published in American Lutherie #91, 2007 François Leonard of Port-Louis, France, asks: I’m guitar maker in France and I’ve been following and reading articles in American Lutherie since many years. I had recently an order for a 10-string guitar and I’m asking myself how much I need to reinforce the design of the bracing. My bracing is not so different from the one Jeffrey Elliott uses and talks about in his AL#56 article “Shaping the Sound.” Jeffrey R. Elliott of Portland, Oregon, responds: My experience is more extensive with 8-string guitars, but I believe the same principles apply. I suggest the following: Select top wood that is more stiff than you would choose for a 6-string, one with all the characteristics you usually look for, but also with a somewhat extended tap-tone range toward the lower pitches.

Posted on June 6, 2024May 27, 2025 by Dale Phillips Letter to the Editor: Domino Guitar Article in AL#85 Letter to the Editor: Domino Guitar Article in AL#85 by Scott van Linge Originally published in American Lutherie #88, 2006 Hi Tim, I read with interest the article on resurrecting the ’30s Regal Le Domino guitar in AL#85. On p. 48, the second picture from the top shows the body with the back removed and the remaining two lower bout back braces still in place. What caught my eye is that they were — (drum roll) — parabolic both lengthwise and possibly in cross section, although that aspect is hard to discern. Similarly, the remaining upper transverse brace on the top is also parabolic, lengthwise. While rounded, it is not parabolic in cross section. The replacement back braces, are instead, fashioned after the heavy ones used by Martin in the ’50s, and appear noticeably taller than the original parabolic ones. From my viewpoint, they inevitably will dampen the back, preventing it from having the reinforcing capability that the original parabolic braces would have afforded. In addition to using parabolic braces on the back, Martin used some on the top, specifically the short side braces and the arms of the X brace, during their “golden era” — a fact that most luthiers and companies who copy what Martin did then (including Martin, now) seem to have missed. In fact, I have only revoiced one guitar (a Collings) that had side braces perfectly parabolic and balanced to the forces on them, so that I did not have to reshape them to bring out the highs. Apparently in lutherie, as in politics, certain lessons from the past are sometimes lost or deemed unimportant. ◆
Posted on March 2, 2024May 14, 2025 by Dale Phillips High School Dreams High School Dreams by Dave Schneider Originally published in American Lutherie #10, 1987 and Big Red Book of American Lutherie Volume One, 2000 Years ago, I wanted to do something different, something no one else was doing. I wanted to own my own business as a guitar maker. I’m living out my high school dreams. My father showed me the art of fine craftsmanship when I was a boy. My high school woodworking teacher was a luthier. As I was one of the more advanced students he asked me if I was interested in making a guitar. I looked at Irving Sloane’s Classical Guitar Construction and told him I thought it looked too difficult, but later I said I would try. I needed a good challenge because I wasn’t really interested in academic subjects.

Posted on April 12, 2021May 20, 2025 by Dale Phillips Making Lining Strips — One Making Lining Strips — One by Rolfe Gerhardt Originally published as Guild of American Luthiers Data Sheet #71, 1978 and in Lutherie Woods and Steel String Guitars, 1997 I used to make lining strips one at a time, a long, tedious process. Then I visited Charlie Hoffmann in Minneapolis and was inspired to work out this gang-saw setup. The saws are 6" plywood saws, very small kerf, and are spaced on the radial arm shaft with 1/4" spacers. Three blades fit comfortably on my radial arm saw. The holder is a board with a guide strip and two hold-down springs. This holder is clamped to the radial arm saw table. I hold the strip I am sawing with my other hand.
