2024
AL#151 p.24               
Tobias Braun                                                                                           

▪ How do you explain that the glue squeeze-out in some fine old guitars by Spanish masters drips the wrong way? Seems like that could only happen if the top was glued last, face-up. The key to the mystery may be an unusual century-old workboard from the shop of Santos Hernández. Tune in for the rest of the story. Mentions Jose Romanillos, Marian Harris Winspear, Jeffrey Elliott, Richard Brune, Alberto Martínez, Domingo Esteso, Enrique Garcia, Francisco Simplicio, Miguel Simplicio, Marcelo Barbero, Marcelo Barbero (Hijo), Arcangel Fernández Léonard Plattner, Faustino Conde, Mariano Conde, Julio Conde, Felipe Conde, Felipe Conde Crespo, Modesto Borreguero, Hernández y Aguado, José Ramírez III, Julián Gómez Ramírez, Manuel Ramírez, Antonio Torres, Robert Bouchet.

▪ A cheap mail-order gizmo for measuring tire tread wear; a pair of nippers; a scrap of plexi; a bottle of superglue. Put them all together and you’ve got a sweet tool like the cool kids use. Mentions Chris Alsop.

Denny’s Jigs, Part Two

2023
AL#150 p.32               
January Williams                                                                                           

▪ Author Williams bought the lutherie estate of the late Denny Stevens several years ago. He has taken an archeological approach to it, pondering over the nicely crafted gizmos he has discovered, and reporting them to us as he figures out the function of the various treasures.

Meet the Maker: Ken Parker

2023
AL#149 p.4               
Mike Doolin   Ken Parker                                                                                       

▪ Can you believe we have never “met” this guy? He’s a giant of the American Lutherie Boom, he was at the Guild’s 1979 Convention, and he has been a GAL member for over twenty years. The world knows him as the maker of the Fly solidbody guitar, but now he has returned to his first love: the archtop guitar. Mentions Larry Fishman, John D’Angelico, Jimmy D’Aquisto, Scott Chinery, Orville Gibson, Lloyd Loar, Raphael Ciani, Nick Lucas, Michael Greenfield, Sam Zygmuntowicz.

Quick-and-Dirty Magnetic Thickness Gauge

2023
AL#149 p.58               
Jon Sevy                                                                                           

▪ A couple of cheap gizmos from Harbor Freight can be cobbled together to let you measure the thickness of the sides or plates of an assembled guitar.

Making a Centerline Square

2022
AL#147 p.56               
John Calkin                                                                                           

▪ In lutherie work, you often need to make something accurately perpendicular to the instrument’s centerline. Squares designed for carpenters and machinists don’t do the job as well as these simple and inexpensive clear-plastic tools.

Accurate Resawing

2022
AL#147 p.64               
Bob Gleason                                                                                           

▪ When doing a small resawing job in the shop, it may seem intuitive to set the fence of the bandsaw close to the blade. You never have to move the fence. But there are good reasons to do it the other way and move the fence after each cut. The clue is in the title.

Basic Steel-String Guitar Action Setup

2022
AL#147 p.24               
Robbie O’Brien                                                                                           

▪ Lutherie uber-pedagog Robbie O’Brien has taught beaucoup guitar makers and repair techs to set the action of steel string flattops, so his thoughts on the matter are crystal clear. Here he steps us through the process in a relaxed, logical, and concise presentation. From his 2017 GAL Convention workshop.

Mark French                                                                                           

▪ In this concluding episode of the series, the neck is fretted and the frets are filed and polished. Threaded inserts are installed in the heel and the neck is attached. Finally, the bridge is glued on, the nut is set in position, and the guitar is strung and set up.

The Charles Fox Guitar-Building Method, Part Five

2021
AL#143 p.22               
Mark French   Charles Fox                                                                                       

▪ In this article the fretboard is slotted, crowned, and glued to the neck. The neck is then shaped.

Ukulele Scale Intonation

Peter Hurney                                                                                           

▪ Here’s a direct and accurate real-world method for calculating the exact position of a uke bridge. The jig does all the work and considers all the variables. No math required!

The Seven-Year Itch

2020
AL#141 p.41               
Erik Wolters                                                                                           

▪ Wolters started his first instrument-making project later in life than some. But with an excellent mentor and years of patient determination, he completed a doozy of a first guitar. Dreams can come true. At least lutherie dreams.

Stiffer Guitar Linings

2020
AL#141 p.47               
F.A. Jaen                                                                                           

▪ These linings are something like reverse kerfing, but they are built up in place, starting with an ingeniously aligned set of individual blocks. There’s always a new way to do it.

Guitar Making with an X-Carve CNC Router

2020
AL#141 p.50               
Mark French                                                                                           

▪ Here come the robots. Although CNC routers are not yet at the Jetsons stage, we are far beyond the days when computer-driven tools were only in luthiers’ dreams, not their workshops. Mark French brings us up to date as he selects and installs an inexpensive machine in his home shop.

Making Notched Straightedges

2020
AL#140 p.58               
Bob Gleason                                                                                           

▪ Straightedges that are notched to fit over frets have become popular tools for judging the straightness of fretboards, and for projecting the surface of the board for setting neck angles. You can make your own, with the advantage that you can use any fret scale. Here’s how.

Chalk-Fitting Guitar Braces

2020
AL#140 p.2               
Stephen Marchione                                                                                           

▪ The braces in an archtop guitar are very similar to the bars in fiddles, and Marchione fits them with the same traditional techniques. The mating surface of the brace is roughed out with a chisel, then refined with a small plane, and perfected with files and scrapers. Chalk shows the whole truth of the fit. Believe the chalk.

Letter to the Editor: Americans Should Use Metric System

2019
AL#138 p.2               
Rolf Hagglund                                                                                           

▪ The author says we Americans should just go ahead and join the rest of the civilized world in using the metric system.

Questions: Glue Joint Clamping Pressure

2019

James Blilie                                                                                           

▪ How much clamping force do different types of clamps exert? Blilie shows us how to calculate the force for some kinds of clamps, and comments about how much force is enough.

Measuring Scale Length of Fretted Instruments

2019
AL#136 p.48               
R.M. Mottola                                                                                           

▪ What’s the scale length? Isn’t it just twice the distance from the nut to the 12th fret? Yeah, kinda, but there can be a lot of complicating factors when working on old instruments. Like maybe the nut position was compensated, or just cut wrong. Or maybe the 12th fret was a little off. The fret positions might have been calculated using the old rule of 18. Here’s how to find out what’s really going on.

A Guitar Is Born: Attending Charles Fox’s Hands-On Guitar Making Course

2019
AL#136 p.54               
Mark French                                                                                           

▪ Author Mark French has made a lot of guitars over the years, but when he wanted to up his game he attended an intensive two-week course by the dean of all American lutherie teachers, Charles Fox. Four students each built a guitar in the white from scratch and strung it up.

Questions: How Hide Glue is Tested for Gram Strength

2018
AL#134 p.69               
Eugene Thordahl                                                                                           

▪ How do they test for hide glue gram strength? It’s actually kinda technical and involves expensive lab gear. But Thordahl tells us how to get a good estimate the easy way.

Setting a Violin Neck Like a Professional

AL#135 p.4               
Charles Rufino                                                                                           

▪ Here’s a close look at the process of setting a violin neck. No innovative tools or new miracle adhesives here; just good old-fashioned methodical, careful work with traditional toos and designs. From his workshop at the 2017 GAL Convention.

Training the Next Generation

AL#135 p.16               
Dan Erlewine   Erick Coleman   Chelsea Clark                                                                                   

▪ “Uncle Dan” Erlewine has been a constant presence in the American Lutherie Boom era, because he personifies the can-do ethos that underlies the whole dang movement: figure something out, and tell everybody about it. As a young man hoping to move from rocker to luthier, he found a generous mentor in Herb David of Ann Arbor, Michigan. Dan has paid that forward many times as he has brought young people into his shop and given them a place to grow. Mentions Herb David, Mark Erlewine, Jerry Garcia, Albert King, John O’Boyle, David Surovel, Bryan Galloup, Charlie Longstreth, Tom Erlewine, Gary Brawer, Joe Glaser, Steve Olson, Albert Garcia, Elliot John-Conry, Adam Fox, Exodus Almasude, Johan Powell, Max Feldman, Paul Lampley, Aaron Smiley, Rodrgo Gomez, Chelsea Clark. From his lecture at the 2017 GAL Convention.

A DRO Fret Slotter

Mark French                                                                                           

▪ Want a robot lutherie apprentice? It is here today and it is cheap. But it doesn’t look like something from the Jetsons. It looks like this; a digital readout connected to a lead screw. With a friendly whirr, it will move the saw guide right up to the next fret position for you. But get your own dang coffee.

Seeking Quality and Consistency in Classical Guitar Sound

2018
AL#134 p.34               
Greg Byers                                                                                           

▪ So you made a classical guitar, and it sounds good. You want your next one to sound good, too. You want your output to be consistently good. How do you do that? After decades of lutherie experience, Byers has developed a method of recording the frequency responses of the soundboard at each major stage of construction. Does the tap-tone of the raw top set tell the whole story? No, but it can help you steer the project to a successful conclusion.

Talking about Tone

2018
AL#134 p.52               
Chris Herrod                                                                                           

▪ You’ll often read article in American Lutherie where scientists explain the sound of guitars in terms of resonant frequencies and onset transients. On the other hand, longtime wood merchant Chris Herrod is here to give the metaphoric pendulum a big old shove back to the right-brain tradition of using evocative adjectives like “dry,” “creamy,” and “poignant.” He also discusses psychoacoustics research and how confident we should be about our “ears.”

Making Long-Radius Curve Templates

2018
AL#134 p.60               
Mark French   David Zachman                                                                                       

▪ There are times when a luthier may want to draw a good long-radius arch. If jury-rigging a 25-foot compass seems like a hassle, you may have been tempted to just bend a straight stick a little and call it good. Turns out that’s a better solution than you may have thought. This article evaluates several techniques and gives the math that undergirds them.

Meet the Maker: Mark French

2018
AL#133 p.22               
R.M. Mottola   Mark French                                                                                       

▪ Mark French was a kid who took guitar lessons and paid the guy at the music store to change his strings. He went on to be an aerospace engineer, but with all that book learning he still did not know how guitars worked. Now he teaches college courses on guitar making and hangs out with captains of industry at Fender and Taylor.

Voicing the Modern Mandolin

2017
AL#129 p.24               
James Condino                                                                                           

▪ Condino has developed a clever process by which he can string and play a new mandolin very early in the building process. This makes voicing much more accurate,a nd it reduces the risk of experimental materials and bracing patterns considerably. Must see to believe. Mentions the work of Lloyd Loar at the Gibson company in the 1920s.

A Large New Set of Stiffness Data for Lutherie Woods and a Proposed Standard Test Method

2016
AL#128 p.58               
James Blilie                                                                                           

▪ We all have ideas about the stiffness of brace wood, probably based on a combination of intuition, hearsay, and informal flexing. Blilie aims to accumulate more quantitave data. Here he reports on his latest tests. He also describes his methodology and the reasoning behind it. This is Blilie’s second article on this topic. The earlier one is in AL128. A third article appears in AL133.

A Homemade Magnetic Thickness Gauge

▪ You, too, can make a gauge for measuring the plate thickness of finished instrument, and Bieber’s tool comes in at 1/30th the cost of a commercial tool. With 2 photos and a drawing.

This article has been nominated as one of the Guild’s fifty best articles published before 2010.

The MacRostie Mandolin Deflection Jig

2008
AL#94 p.50               
Don MacRostie                                                                                           

▪ MacRostie’s clever jig measures the top deflection of a carved mandolin under string load at any stage of its construction. It is a valuable tool within the reach of any luthier.

▪ Hurd believes that the fastest way to great instruments is science, and it’s hard to argue with such a rational man. His jigs measure the deflection of top plates while under tension, and once he carves the top and braces to the numbers he wants he’s done. Period. Sort of makes intuition obsolete. This could also be math heavy if he didn’t offer an Internet spread sheet to ease the pain. With 7 photos and 7 figures/charts.

▪ The authors measured frequency response of dozens of similar Taylor guitars using a hammer and a noncontacting laser displacement sensor. The big surprise was that guitars made of various woods didn’t differ very much. Well, some people were surprised. With 4 photos and 7 graphs.

Optimizing Playing Surface Geometry

2007
AL#89 p.56               
R.M. Mottola                                                                                           

▪ Most repair people know that on a fretboard with a tight radius the upper frets have to be milled flatter than the first frets if the player wants to bend strings without “fret-out.” Most just file several times until the get the results they are after. What they are really doing is trying to turn the playing surface into a conical section. Mottola’s method is more precise. Consider it the thinking man’s way to dress frets for the most optimum action. With 7 figures, 6 photos, and a chart.

The Chanlynn Deflection Machine

▪ Gunsmith Mark Chanlynn built Calkin a machine to precisely measure the deflection of a guitar top under a constant weight. There are no plans here, but it’s pretty obvious how it works, and just as obvious how it might help you make better guitars. With 3 photos.

This article has been nominated as one of the Guild’s best articles published before 2010.

Low-Tech Prototyping Jigs and Methods

Tim Shaw                                                                                           

▪ Shaw has worked for large guitar companies for decades. Currently with Fender, he runs an independent shop that makes prototype instruments for all the factories that fall under the Fender banner. He also does repairs on discontinued models where the factory equipment has been dismantled. Accomplishing one-off projects or small runs of parts is no different for a big company than for an independent luthier, they just have the luxury of big-budget equipment. Shaw’s methods of jigging up for parts manufacture incorporating speed and safety can be used by many one-off shops to hustle production and instrument development. Good stuff from one of the aces in the business. With 34 photos.

Product Review: Stewart-MacDonald Fret Scale Rules

▪ Fleishman is at his humorous best here, hunting the past for how frets used to be laid out, why they were often wrong, and why the new Stew-Mac rules are tools worth having. Did you know there are at least three ways to calculate fret spacing? Did you know they vary in their results? Can musicians hear the difference? With 1 photo and a chart.

▪ Toolman Harry examines three new measuring devices from Stew-Mac and finds them all to be accurately made and useful. The tools are the Fret Rocker (for finding high frets), the String Action Gauge (for measuring string height), and the String Spacing Tool (for laying out nuts and perhaps saddles). With 3 photos and a diagram.

Tales of Topographic Arches

2004
AL#78 p.45   BRB7 p.199            
Michael Darnton                                                                                           

▪ By making a topo map of the spherical arch you wish your top or back to be (in 1/32″ intervals in this example) one only has to lay an outline of the guitar on the map and chart the contour of the sides. So easy. So elegant. So how come it wasn’t more obvious? With one photo and one diagram.

Product Review: Spot Check Thermometer

2003
AL#76 p.58   BRB7 p.510            
John Calkin                                                                                           

▪ The reviewer tries out the Spot Check contact thermometer on his side-bending machine and makes some interesting discoveries. This tool is too cheap and useful to be without. With 3 photos.

Hands-On Archtop Mandolin Making, Part One

2003
AL#75 p.12   BRB7 p.416            
Peggy Stuart   Don MacRostie                                                                                       

▪ The author describes her mandolin making class with Red Diamond mandolin builder Don MacRostie, giving us a photo-heavy series that should be of practical use to anyone in the mandolin field regardless of their experience. The emphasis is on hand tools, though power tools are used to add efficiency. With 68 photos and 4 drawings, this is the first in a four-part series.

It Worked for Me: Mandolin Side Heights

1999
AL#58 p.58   BRB5 p.501            
John Monteleone                                                                                           

▪ A good method for finding the height of mandolin family sides using a violin soundpost height gauge.

Length of Newt’s Tail by Width of Dragon’s Hair

1998

Ken Sribnick                                                                                           

▪ Sribnick believes that consistent accuracy stems from shop standards. One set of measuring tools, one set of templates, one style of doing things. He makes a good case, too. With 3 photos.

Product Reviews: Wood Thickness Indicator, Nut Files, Fret Slot Cleaning Tool

1998
AL#54 p.58   BRB5 p.444            
Harry Fleishman                                                                                           

▪ Fleishman tries out a tool for puncturing archtop plates to establish depth of cut, likes it, but finds that the standard size tool is for violin makers and guitar makers must special order; the nut files of a lifetime come into his shop; a good tool that Everyman can afford turns out to be nice fret slot cleaning tool.

Product Reviews: Sewing Shop Finds; Cutting Burs; Spring Clamps

1997
AL#52 p.58   BRB5 p.441            
Harry Fleishman                                                                                           

▪ Ever thought to look in a fabric store for lutherie tools? I’ll bet’cha that Harry beat you to it. He found a deal on aprons, some good layout tools for design work, and bias tape for tying on bindings. Then he opened a Woodcraft catalog and discovered clamps and a carbide burr cutter he couldn’t live without. Just one more column demonstrating why the editorial staff has developed a fatherly concern for their toolman’s life on the edge of lutherie.

The Guitar Neck: Its Design and Physics

1996
AL#48 p.22   BRB4 p.394            
Ervin Somogyi                                                                                           

▪ This 1995 convention lecture covers the physical nature of the neck. Not how to do the work, but how to make a neck for maximum playability and instrument performance. Both steel string and classical guitars are discussed. With 1 photo and a slough of diagrams.

Developing Models for Contemporary Violinmaking

1995
AL#44 p.20   BRB4 p.230

▪ Apparently not every violinist is determined to have a fiddle that looks 300 years old. Rabut has made some interesting attempts to update the violin without sacrificing the tone that everyone demands. Can’t wait until these babies start showing up in symphonic orchestras. With 21 photos.

▪ This time the GAL’s Toolman tests a Stewart-MacDonald diamond coated fret file, and the Hacklinger gauge for measuring the thickness of instrument tops and backs. He likes the file enough to recommend it. He likes the gauge, too, but its high price puts him off.

Product Reviews: Sabine Stealth Tuner

1995
AL#41 p.48   BRB4 p.429            
Harry Fleishman                                                                                           

▪ Fleishman examines the battery-powered Stealth guitar tuners from Sabine, which are meant to be mounted on the guitar. He finds them useful but aesthetically hard to hide on the instrument.

Segovia’s 1937 Hauser: Top and Back Thicknesses

1994
AL#38 p.24   BRB4 p.34            
R.E. Brune                                                                                           

▪ Brune made a map of plate dimensions using a new (and expensive) gizzy called the Elcometer. Then he decides that plate thickness probably isn’t so big a deal. Well, at least you have a model to guide you.

Electronic Answer Man

1994
AL#37 p.56   BRB4 p.416            
Rick Turner                                                                                           

▪ Turner’s column is all about the essential electronic measuring instruments for the guitar shop.

▪ To the uninitiated, violin setup seems to have way too many steps for the small number of moveable parts involved. Taken one step at a time, the mystery falls away. Darnton explains the tools and procedures he uses to get the most out of a violin. This segment includes fitting pegs, correcting problems with the nut, making a fingerboard, and fitting a soundpost. Part Two is printed in AL#37. With 30 photos.

Alan Carruth                                                                                           

▪ Accessibility and usefulness are the keys to this segment of Carruth’s study. He addresses the archtop, flattop, and classical guitars, and even builds a flattop out of oak to compare its tuning modes to conventional tonewoods. With many mode diagrams and plate graduation charts. Too many scientific studies leave the luthier asking, “So what do you want me to do?” Carruth offers some real-world suggestions. Parts One and Two were in AL#28 and AL#29.

▪ Carruth tries to keep it light as he describes the glitter dances that should improve your violins, and even sheds light on cello plate tuning. If you feel threatened by the dryness of science just relax and give it a try. Carruth is on your side. Really. With a whole bunch of drawings. Part One was in AL#28. Part Three follows in AL#30. The entire series appears in BRB3.

Free Plate Tuning, Part One: Theory

1991

▪ Most acoustic scientists are not prepared to reduce their work to a plane-by-the-numbers chart of an instrument top.Neither is Carruth. It remains to be seen what improvements free plate tuning will offer to the average guitar, but there is every chance that luthiers who ignore the work as an inartistic invasion of their craft and art will be left in the dust. Carruth invites you to get on board right now. Parts Two and Three are in AL#29 and AL#30. The entire series apperas together in BRB3.

▪ Darnton’s contrivance marks the finished thickness on violin plates that have already been carved to within 1mm-2mm of final tolerances, and it is simple to make.

Special Caliper for Cello

1989
AL#18 p.44   BRB2 p.246            
Jack Levine                                                                                           

▪ Levine made a deep-throated caliper for accurately measuring the thickness of the cello plate that is not removed, when the other is.

Is Your Wood Ready To Use?

AL#13 p.44   BRB2 p.24            
George Manno                                                                                           

▪ Manno points out there is a difference between wood that is dry and dry wood that is well seasoned, and offers a test for both. He maintains that only dry, well-seasoned wood is worth using.

Conrad Color System

Gregory Jackson                                                                                           

▪ Jackson comments on the basic principle upon which electronic moisture meters work, use of the meters, and why you should not try to cobble together your own.
