I arrived in Saigon, age eighteen years plus one week. I had joined the Army on my seventeenth birthday after dreaming of it for two years. I felt lucky when the Vietnam War started to get serious, because it was my chance to be a hero. But the rule was that you had to be eighteen years old to go. OK, I was the classic stupid kid. I ended up doing two tours of duty in Vietnam, by my own choice. I don’t know why, but I loved that place from the first day. That has never changed for me. I did become disenchanted with what we were doing there. These were the “light at the end of the tunnel” days, and those of us on the ground were already starting to realize that this was the first war we would not win. But even when things were rough, there was no other place I wanted to be. Become A Member to Continue Reading This Article This article is part of our premium web content offered to Guild members.

Posted on July 1, 2022May 28, 2025 by Dale Phillips The Right CAD Curve The Right CAD Curve Bezier Curves, Not Splines, Are Truly Smooth Curves by David Golber Originally published in American Lutherie #72, 2002 and Big Red Book of American Lutherie Volume Six, 2013 Bezier curves, as opposed to splines, have been known since the 1970s. They are supported by AutoCAD and AutoCAD LT, but not by many other popular CAD packages. What are they, and why do we care? It’s easiest to start with an example. Fig. 1 shows the outline of a harpsichord. Look at the curved side. The coordinates of the points are from Kielklaviere,1 which describes the curved side of the instrument by listing the coordinates of points along the side. The curve in Fig. 1 is the ordinary spline through those points. Fig. 2 shows that one of the points is erroneous enough that it clearly makes the curve bumpy.

Posted on July 1, 2022May 9, 2025 by Dale Phillips An Experimental Tenor Violin An Experimental Tenor Violin by Frederick C. Lyman, Jr. Originally published in American Lutherie #18, 1989 Building a musical instrument always involves making decisions. Even if the instrument is a familiar model that has been built many times before, the actual pieces of wood are unique, and require unique treatment. Obtaining predictable results, even such as might appear to be instances of mere routine uniformity, usually requires a surprising degree of conscious, intelligent control. In respect to quality of sound, the more an instrument is produced by an invariable automated process, the more variable and inconsistent may be the result. That is because we are dealing with subtle differences which add up. The more intelligence that can be applied to the many decisions that have to be made, the better the cumulative result can be. Of course, wrong decisions can also be made. This can happen easily when the project being undertaken is one-of-a-kind, where the lessons of past mistakes cannot be applied to the problems.

Posted on July 1, 2022May 27, 2025 by Dale Phillips A Different Way of Defining Body Shapes A Different Way of Defining Body Shapes by Mark French Originally published in American Lutherie #88, 2006 As I look through American Lutherie, I am struck by the advances in the tools some of us use to make our instruments. While there will always be the traditionalists who do most of their work by hand, more of us are using computer-controlled machines to make jigs or parts. Even the musical instrument lab here at Purdue (www.metalsound.org) has its own CNC router. Large manufacturers like Taylor Guitars use CNC equipment for the majority of their building operations. An obvious advantage of all this cool stuff is that parts can be made much more precisely. However, the parts can only be as precise as the instructions that are driving the machines. Look through your favorite book on guitar making and find the section on laying out the body shape. Even the best books, like Making an Archtop Guitar by Benedetto and Guitarmaking: Tradition and Technology by Cumpiano and Natelson, offer only the most basic description of the shape. It’s pretty common for the instructions to start with something like “draw a straight line on a sheet of brown wrapping paper to use as a centerline.” Become A Member to Continue Reading This Article This article is part of our premium web content offered to Guild members.

Posted on July 1, 2022May 23, 2025 by Dale Phillips Questions: Fingerboard of Orpharion Questions: Fingerboard of Orpharion by Chris Goodwin Originally published in American Lutherie #93, 2008 Wayne S. from the Internet asks: Can someone tell me what the idea behind the layout of the fingerboard of the orpharion is? Chris Goodwin from the Internet responds: The explanation lies in the limitations of metallurgy in the Renaissance. The basic problem of lute family instruments is that you are looking for strings which are all the same length to make a musical sound with open tunings ranging over two octaves. If you have a reasonably fine bass string that makes a good musical note and provides reasonable intonation when fretted, then the top string has to be very thin and under very high tension to sound two octaves higher. They couldn’t make wires strong enough in those days. Orpharion, copy after Francis Palmer, made by Peter Forrester. Photo by Peter Forrester. The sloping frets partially resolve this problem by making the bass strings longer than the treble. The treble string could be shorter, and so didn’t have to be at such high tension to sound at a high note, and the bass strings didn’t have to be fat and chunky (and produce a dull unmusical thud, instead of a clear note) because they were longer. This is explained very well by Ian Harwood in an (English) Lute Society booklet on the Helmingham bandora. Purchase the booklet from the Lute Society: Lutesoc@aol.com.
