Benz Tschannen from Fallon, NV provides an update to a question he asked in AL#89 about “ossification” of guitar soundboards: I did some experimenting: Two pieces of spruce and two pieces of cedar, ≈2"×4"×.10", washed one each with a solution of sodium silicate, the other with water. Let dry, then coated with two coats of shellac each. After a year the result is inconclusive. Sometimes the silicate pieces seem higher pitched, sometimes the water washed ones do. The big change is in color: the silicate turns the spruce yellow and the cedar a darker brown. I don’t want to find out what it does to the colors of the rosette, so I am abandoning this quest for now. ◆

No, not that Woodstock, but a one-shop, no-houses Woodstock in North Queensland, Australia. At last the moment had arrived. It was a typical hot summer’s day and I was armed with the necessary tools. There was still that feeling of uncertainty in my mind that what I was to do was totally criminal. Sharing the shed with the ’dozers and tractors was an old upright Victor piano. Nobody wanted it anymore so I was able to carry out my plan. At home, our towns usually have a festival each year, and in that festival procession there is always an old car whereupon, for a fee, you may smash with a sledge hammer. Well, I wasn’t in that kind of mood, but I was still going to reduce this piano to an unrecognizable mess, but, I hope with a more dignified ending.

Posted on March 4, 2022May 28, 2025 by Dale Phillips Adirondack Spruce Growth Rates and Accessibility Adirondack Spruce Growth Rates and Accessibility by Ralph S. Charles III Originally published in American Lutherie #81, 2005 and Big Red Book of American Lutherie Volume Seven, 2015 With a day job in the forestry and logging industry, I know a little something about wood. After thirty years of selling saw logs and pulpwood for a living, I thought that a move into the tonewood business would be a natural transition into retirement. Membership in the GAL, however, has uncovered a realization that some luthiers may appreciate my perspective on tree growth rates in general, and Adirondack spruce in particular. The grading of wood for instrument tops takes into account at least the following considerations: evenness of grain, straightness of grain, tightness of grain, color or discoloration, location or lack of knots, figure, heavy grain lines, pitch pockets, foreign objects (bullets and barbed wire), closeness to quarter and runout, and stiffness. The following discussion is directed at the evenness and tightness of grain which are a direct result of the laying down of the annual growth ring.

Posted on December 21, 2021May 21, 2025 by Dale Phillips Early Engelmann Early Engelmann by Jan Callister Originally published in Guild of American Luthiers Quarterly Volume 10 #3, 1982, updated 1993 and Luthier Woods and Steel String Guitars, 1997 In 1975, while completing my third guitar, I became very interested in the interplay of the different woods and their significance in the construction of a guitar. Most beginning guitarmakers, I am sure, have had the same interest. However, I questioned the use of European spruce as the most esteemed tonewood. Why didn’t our own domestic spruce wood have the same qualities? I began researching the literature to gain information on our own domestic spruce and its use for musical instruments. I found some references concerning Sitka spruce, mainly short paragraphs relating to tonal characteristics of violins. I couldn’t help wondering if the Engelmann spruce from the forests on the mountains just east of my home near Salt Lake City might have possibilities for guitarmaking. My research revealed hints that Engelmann had been used successfully by a few violinmakers as far back as the 1900s. A local industrial arts professor noted for his knowledge of woods, however, told me that Engelmann had no merit as a tonewood. Undaunted, I continued my research and found positive confirmation of Engelmann’s tonal value from Peter Prier of the American Violin Making School in Salt Lake City, Sam Daniels from Jerome, Idaho, and some records of R. Peter Larsen who had built over 100 violins in the late 19th century and said Engelmann was “superior in tone to Italian wood.” Become A Member to Continue Reading This Article This article is part of our premium web content offered to Guild members.

Posted on September 22, 2021May 6, 2025 by Dale Phillips The Paul Schuback Story The Paul Schuback Story from his 1986 GAL Convention lecture Originally published in American Lutherie #9, 1987 and Big Red Book of American Lutherie Volume One, 2000 Paul Schuback was born in Barbados in the West Indies in 1946 and moved to the United States at the age of nine months. Through his experiences and training, he lived in thirty-three different homes before the age of twenty. His interest in musical instruments began when he was quite young, when he took up the violin at the age of seven. At the age of nine he began playing the cello, joining a youth symphony orchestra in Utah at the age of fifteen. Then, before graduating high school, he began his career as a luthier with a three-year apprenticeship to master Rene Morizot, in Mirecourt, France. Following this, he specialized in violin making in Mittenwald, Germany. He then became a graduate in bow making at the Morizot Freres again in Mirecourt, France. He continued his studies by researching historical instruments in France, Germany, Switzerland, and Italy. From 1968 to 1971 he worked as journeyman in the Peter Paul Prier violin shop in Salt Lake City, Utah, before moving to Portland, Oregon, where he established his own workshop and where he resides today.
