Posted on October 10, 2025October 10, 2025 by Dale Phillips Production Techniques for the Custom Luthier Production Techniques for the Custom Luthier by Charles Fox from his 2011 GAL Convention workshop Originally published in American Lutherie #110, 2012 Tim Olsen: It’s my pleasure to introduce Charles Fox, America’s lutherie teacher number one. Charles, didn’t you used to teach in yurts? (laughter) There weren’t many lutherie teachers in America during the early ’70s. Charles has a lot of credits, but to me, the credit that beats all others is that this is the guy who taught Fred Carlson. That means a lot to me. So please welcome Charles Fox. (applause) Charles Fox: Yes, I am proud of Fred. In fact, I’m proud of so many people who have been through my classes. How many here have spent time with me? Wow, look at that. You’ve gotten so old. (laughter) I arrived late yesterday, and John Greven was just finishing his talk. I went up in the back and looked down, and all I saw was bald and gray. (laughter) We’ve got to do something to get more young people into the field. The way guitar making is evolving suggests a glorious future, but if a new group of people doesn’t come along to take it over, it might have just been a moment in history. Today I’m going to discuss and demonstrate some practical approaches to being more prolific luthiers. Many processes that make guitar making relatively easy, efficient, accurate, and consistent in a production situation can be adapted to the needs of the creative custom builder. Having been in both worlds, I can tell you that there’s a lot you can do to become more efficient without compromising quality.

Posted on June 30, 2024May 14, 2025 by Dale Phillips Mechanical Compliance for Soundboard Optimization Mechanical Compliance for Soundboard Optimization by David Hurd from his 2006 GAL Convention workshop Originally published in American Lutherie #90, 2007 People say, “You’ve got to make fifty or a hundred guitars before you get it right.” That makes me crazy. I feel that if you can do the carpentry of putting an instrument together and have idea of what it should look like, you can get 80% or 90% of the way there in terms of top optimization with a mechanical compliance approach. I build many sizes of guitars and ukuleles using different top woods. I have developed an easy method of testing the compliance of a top, that is, how far it flexes under a given force, with a simple fixture. Being able to measure and compare the compliance values has proved to be a very useful thing in optimizing these soundboards for the best sound and stability when I graduate the edges of the tops and carve the braces. After building and measuring many instruments, I have developed a mathematical model that does a very good job of estimating what the target compliance measurements should be for a given instrument size and string tension. I have integrated the model into a spreadsheet which you can use by plugging in just a few simple measurements.

Posted on June 30, 2024May 14, 2025 by Dale Phillips Construction of the Colombian Tiple Construction of the Colombian Tiple by Anamaria Paredes Garcia and R.M. Mottola Originally published in American Lutherie #90, 2007, Big Red Book of American Lutherie Volume Three, 2004 American Lutherie #82 featured an article and plan for the Colombian tiple by Bogotá luthier Alberto Paredes. This is a companion article to that one, featuring a detailed description of how the tiple is constructed in Sr. Paredes’ shop. The design of the tiple is heavily influenced by that of the classical guitar, but as it was not directly descended from the classical, this instrument has unique characteristics. With its multiple courses of steel strings, the construction of the tiple has to be able to withstand much higher static string tension than a classical guitar. The top is cut from bookmatched spruce, nominally 3MM thick. The two halves are generally cut out on the bandsaw at the same time, as shown in Photo 1. The center seam edges are jointed, first on the jointer (Photo 2). Following machine jointing the top halves are finished up on the shooting board using a hand plane. Note that the halves are simply pressed by hand to hold them down on the board during shooting (Photo 3). Glue is applied to the center seam surfaces (Photo 4) which are then clamped using simple cauls to a flat, waxed gluing board (Photo 5). Once the glue is dry the squeeze-out is stripped off the back side of the top.

Posted on June 30, 2024May 14, 2025 by Dale Phillips The MacRostie Mandolin Deflection Jig The MacRostie Mandolin Deflection Jig by Don MacRostie from his 2004 GAL Convention workshop Originally published in American Lutherie #94, 2008 The mandolin world is small enough that if you’re even thinking about building one, you probably already know who Don MacRostie is. Don is an inventor, and he’s done more for Stewart-MacDonald than we will ever hear about. He’s been making Red Diamond mandolins for two decades now. At the 2004 GAL Convention Don discussed one of his research tools and told us how he applies it to his construction process to make the sound of his finished instruments more consistent and predictable. — John Calkin At the GAL Convention in 2001, Charles Fox floated the idea of teaching a mandolin building class at his American School of Lutherie. As a result, I taught a two week class, building A-style mandolins from scratch. The only thing we started with was thickly precarved oversize tops and backs. Everything else we made totally from scratch. It was a great experience. Peggy Stuart, a student in the class, documented the experience in a series of American Lutherie articles (AL#75–AL#79). Tim Olsen asked me to demonstrate and explain the plate-deflection machine we used in the class at this convention, so that’s why we’re all here.

Posted on June 30, 2024May 14, 2025 by Dale Phillips Electric Guitar Setup Electric Guitar Setup by Erick Coleman and Elliot John-Conry from their 2006 GAL Convention workshop Originally published in American Lutherie #98, 2009 Guitar companies can only set up their guitars to a certain level and still be cost effective. So even a lot of brand new guitars are brought to our shop to be super set up. Since Erick works for Stewart-MacDonald and we both work in Dan Erlewine’s shop, most of the tools and materials we’re going to mention today are available from Stew-Mac. We do all the neck work on the neck jig. This jig simulates the guitar under string tension. If you simply remove the strings, set the guitar on your bench, tweak the truss rod until everything looks level, then proceed to level the frets, you may find that once it is strung again your leveling job has gone to hell. You haven’t accounted for the abnormalities that string tension usually puts in the neck, and neither have you accounted for the effects of gravity differences between the guitar lying flat on your bench and the guitar in playing position. So we not only use the jig to simulate string tension, we tilt the guitar into playing position before the jig is adjusted. We use about a 70° angle to simulate playing position, since few of the guitar players we know have a stomach flat enough to hold the guitar at a 90° angle to the planet.
