Posted on January 15, 2026January 15, 2026 by Dale Phillips Evolving the Dished Workboard Evolving the Dished Workboard by John Calkin Originally published in American Lutherie #65, 2001 and Big Red Book of American Lutherie, Volume Six, 2013 For my money, the dished workboard is one of the most important lutherie inventions ever, making it possible for even rookies to build guitars that are precisely and tightly put together. I’d like to suggest ways to make them more useful. First, though, let’s make it clear what the heck we’re talking about. Guitars were initially built with flat tops. Classical guitars (and not a few steel strings) were built on a flat workboard that more resembled a tabletop than a piece of movable gear, since it was the size of the entire instrument, neck included. The construction method using the Spanish foot required this size, since the neck became a structural part of the body. Mechanical joints such as the dovetail or bolts freed the luthier to build the body and neck as separate units, and the workboard was reduced to a laminated rectangle the size of the body, and was often dispensed with altogether when the body was built inside a mold. In 1975 David Russell Young published The Steel String Guitar, the first guitar construction book recommending domed tops. Young, however, made no mention of the dished workboard, but used more primitive methods to achieve the domed top. It wasn’t until the late ’80s that the spherically domed guitar top began to catch on. (Forgive me if I simply call them SDTs.) The easiest way to build SDTs was on top of a spherically dished workboard, which came on the market about that time. (Let’s not call them SDWs; I’ll explain why in a bit.) The merits of SDTs are not at all obvious to musicians, nor are all luthiers convinced that they are the way to go, but an important thing happened here. Guitar backs have always been arched, and fitting an arched back to a set of bent sides equipped with lining and end blocks has always been one of the bugaboos of lutherie. It’s not easy to do in a professional manner. But with one simple step, it became possible to fit perfectly arched braces to a perfectly arched back, and then to fit the entire assembly to perfectly shaped ribs.

Posted on January 15, 2026January 15, 2026 by Dale Phillips Slotting Fretboards Slotting Fretboards by John Calkin Originally published in American Lutherie #70, 2002 and Big Red Book of American Lutherie, Volume Six, 2013 Many luthiers skip the tedious chore of slotting their own fretboards, and with good reason. Preslotted boards are readily available in most of the common scale lengths, and I’ve never used a prepared board that wasn’t accurately made. However, if you wish to escape the use of ebony or rosewood, or if a strange scale length is calling your name, you may have no choice but to slot your own fretboards. Accuracy and neatness are the attributes of a properly slotted board. Completing the job efficiently while keeping your temper under control requires a few basic tools. Be warned, however, that the frustration factor is harder to control than the necessary accuracy. Fretboard wood is usually the hardest and most abrasion resistant that can be found, and it doesn’t give in to slotting politely. It’s possible to buy your way out of this situation. It’s ironic that the cost of machine slotting is hardly more than a dedicated miter box, and can be a lot cheaper than a deluxe miter box. Assuming, that is, that you haven’t invested in a table saw just to cut fret slots.

Posted on October 10, 2025October 10, 2025 by Dale Phillips Hearing Voices: A Recipe for Voicing the Steel String Guitar Hearing Voices: A Recipe for Voicing the Steel String Guitar by John Greven from his 2011 GAL Convention workshop Originally published in American Lutherie #114, 2013 Let’s discuss a vocabulary for tone. These are the words I use when I talk to my customers. Power. We’re talking about headroom, the ability to get louder when you play harder. Responsiveness. I want a top that will respond easily to a light touch, but it will also sustain under a heavy one. The finished guitar will have a full voice played lightly or heavily or anywhere in between. A lot of guitars require a heavy touch; as playing pressure diminishes, the voice gets thin and loses its full substance. Projection. How far away can you hear it? I want the guitar to throw its voice as far as possible. When I was at Gruhn’s, a 1937 D-28 came in, all original. The top was the thinnest we’d seen on a herringbone, about .090", but it was really stiff. The sound of that guitar was painful, but you could hear it for miles. For a bluegrasser trying to play lead over six banjos, that’s the guitar.

Posted on October 10, 2025October 10, 2025 by Dale Phillips A Summary of John Greven’s Voicing Method A Summary of John Greven’s Voicing Method by Mike Doolin Originally published in American Lutherie #114, 2013 John Greven has been building guitars for fifty years, and has single-handedly built over 2200 guitars in that time. Doing the math, that means he averages close to a guitar a week. Given that kind of efficiency, it’s not surprising that his methods for controlling the sound of his guitars are simple and direct. He’s distilled the huge number of variables down to the handful that he believes are most important, and has evolved testing methods that take only seconds and require no measurement tools. While John is a trained scientist, and does speak of the scientific aspects of guitars and wood, he’s quick to point out that his methods are not scientific, but intuitive and experiential. This is a major problem in documenting his methods: in a sense, you have to be John Greven to fully understand them. They rely on John’s vast experience in building thousands of guitars, and playing those guitars and thousands of guitars by other builders, and on his “photographic” memory for sound, and the database of sounds that his experience and memory have created in his head. Moreover, sound is not accurately describable in words, and tactile sense is not accurately quantifiable.

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.
