Chalk-fitting Guitar Braces

First, have a plan. Know what you’re making. It seems like an obvious thing, but sometimes people start a guitar without a good idea of what the brace layout will be. When I design a new model, I’ll often get a piece of aluminum flashing and lay out a bracing template. If you’re building an historical model, you can transfer the blueprint to a template of aluminum or plexiglas. This gives you a clear idea of what your braces are supposed to be doing, and it lets you be sure that the braces end up where they were designed to go. Photo 1 is a closeup of one of my bracing templates. I use the little holes to make pencil marks on the soundboard.

On a classical guitar, a lot of builders push the big harmonic bars down into the solera, or dished workboard. But that can cause distortion of the top. Even on a Spanish guitar, I take the time to chalk-fit the brace. That gives a better structure with less stress. I highly recommend it.

Low-Stress Archtop Guitar Design

Low-Stress Archtop Guitar Design

by Steve Grimes

from his 2008 GAL Convention workshop

Originally published in American Lutherie #101, 2010



Before I was a luthier I worked as a draftsman for Boeing. I’d rest my head in my hand and hold my pencil, and I could log in a half-hour or 45-minute nap.

In 1972 I realized that if I didn’t change professions, I might as well commit suicide. The first instrument I made was a flattop Martin-style mandolin, and later that year I started building archtop mandolins. I had a preference tonally and visually for oval-hole mandolins, and I’m still addicted to oval-hole instruments.

In ’74 I wandered into McCabe’s Music Store in L.A. and saw a great-looking guitar on the wall. The store was noisy, so I didn’t really get a chance to evaluate the sound, but it sounded good. It was made by Lloyd Baggs, before he started making transducer piezo pickups. That guitar influenced me a lot, and it was similar to this guitar which I just finished. It didn’t have the light sunburst, and it wasn’t made out of curly koa like this one, but they both had flat backs. I immediately went home to Seattle and made my first archtop guitar, with an oval soundhole and a flat back.

Grading on the Curves

Grading on the Curves: Fitting Bars and Bridges on Archtop Guitars

by Steve Andersen

from his 2006 GAL Convention workshop

Originally published in American Lutherie #91, 2007



The first thing I’ll show you today is how I fit tone bars to the top. Then I’ll talk about fitting the base of a bridge to a top, first with this router jig that indexes off the top and gets me really close to the final shape, then moving on to the final fitting. I brought some extra materials if anyone wants to try hand-fitting an ebony bridge or a tone bar.

I use the term tone bar, because I think of braces as being structural. If you built a flattop guitar without braces, it would just fold up. An archtop could be built without braces and it would hold up fine. The archtop’s bars are not so much for structure, so I call them tone bars.

One thing that helps me in the fitting process is that my arching is very consistent from guitar to guitar. The arching templates for my guitars started out based on a D’Angelico New Yorker, and have evolved over the years to what I’m using today. So while I have several body sizes, they have similarities based on what I’ve found works well for my sound.

Letter: NMM Opens Gudelsky Gallery

Letter: NMM Opens Gudelsky Gallery

by The National Music Museum

Originally published in American Lutherie #82, 2005



GAL members —

The National Music Museum on the campus of The University of South Dakota in Vermillion, South Dakota, will celebrate the 500th birthday of Andrea Amati, in whose workshop in Cremona, Italy, the form of the instruments of the violin family as we know them today first crystallized, by hosting an international conference — The Secrets, Lives, and Violins of the Great Cremona Makers 1505–1744, Friday–Monday, July 1–4, 2005. The program brings together individuals who have been at the forefront of archival research in Cremona, amidst some of the earliest, best preserved, and historically most important instruments known to survive. Presenters include Carlo Chiesa, John Dilworth, Andrew Dipper, Roger Hargrave, and Duane Rosengard.

The event is being coordinated by Claire Givens (Minneapolis), a NMM Trustee. Major underwriting is being provided by four prominent American violin dealers: Chris Reuning (Boston), Jim Warren (Chicago), Bob Bein and Geoffrey Fushi (Chicago), and David Kerr (Portland). Registration forms and housing information are available on the NMM website.

A Survey of Guitar Making Books

A Survey of Guitar Making Books

by Graham McDonald

Originally published in American Lutherie #98, 2009



Over the years, I have accumulated quite a few books on building guitars and other stringed instruments, as I’m sure many other instrument builders have. While many of the newer publications get reviewed in American Lutherie and other specialist magazines soon after release, others fly pretty much under the radar and never get much attention or noticed at all.

This is a comparative look at most of the books that have been published (at least in English) as instructional manuals over the past fifty years or so. Most have remained in publication over the years and even the ones that are out of print are usually pretty easy to find, especially through such online retailers like AbeBooks (abebooks.com) or Amazon.
