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.

The results with this method have been uniform hair tension, long-term retention, and reduction in rehairing time. The jig was fabricated from pine and oak. I used oak on all blocks. Item 4 makes a great carving back for ferrule wedges. I average ten bows a month and this method and jig has cut my time in half and increased the quality. On my sketch, items 2A, 2E, 2D, and 2F are the new additions to an old jig. I have made a few small changes. For the lack of a name, I will call this a “hair holder.” Item 2A swings aside to place hair over sponge rubber. The half of a 1/8" dowel holds the hair in place when the wing nuts are tightened.

Posted on April 12, 2021March 6, 2024 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.

For those who have not had the pleasure of her acquaintance, Carleen is one of the founders of the Catgut Acoustical Society and its permanent secretary. She is an able scientist, a great teacher, a fine luthier, and a self-confessed mediocre violist. While working with physicist Frederick Saunders almost thirty years ago she helped rediscover and update the old Chladni method of visualizing the vibrations of plates. Her subsequent research, using Chladni patterns as a window into the differences between good and poor violins earned her a silver medal from the Acoustical Society of America. Violin makers have traditionally used some variant of “tap tone” tuning to guide them in working out the final graduations of the top and back plates. Although the technique seems simple and organic on the face of it, it is in fact very complex. It takes a long time, as well as a good ear and a lot of talent, to learn to tune plates by tap tone. Even those who are good at it don’t always succeed. Felix Savart, back in the 19th century, tried to adapt Chladni’s method to research on violin acoustics, but the technology wasn’t there. Now we have the means, and as we gain more understanding of how the instruments work, we also gain more control over the sound. And it doesn’t only work on violins. Fred Dickens, Graham Caldersmith, and Gila Eban have all done major work in applying the principles of violin acoustics to guitar construction. Of course, there are differences and it takes time and effort to sort them out, but physics is physics, or, as a friend of mine said, “it all comes down to F=mA in the end.” I have found these techniques to be useful, and sharing useful techniques is what the Guild is all about.

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.
