It Worked for Me: Pantograph

It Worked for Me: Pantograph

by Greg Nelson

Originally published in American Lutherie #110, 2012



A pantograph has become my solution for dealing with small pieces of shell for inlay work. This simple device has allowed me to upgrade the quality of my inlay work as well as speed up the process. This is especially true with repeat work such as a logo.

The pantograph is simply a series of rods connected in such a way that if one end is anchored and the other moved, a point between will move exactly the same but at a set fraction of the original movement. My pantograph is set up for a 50% reduction in size thereby giving me greater control of my cutting tool.

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

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

by Ken Sribnick

Originally published in American Lutherie #55, 1998



Don’t hurt me. I’m going to tell you an old joke. How many luthiers does it take to split a dragon’s hair? One to split the hair, and the rest to say, “Oh, that’s how you do it.” At our 1995 convention, I heard a number of luthiers ask about measurement and precision: How do you check this? When is that flat enough? In the spirit of the little joke, I thought it might be interesting to tell you my approach. These surely aren’t the only, or necessarily the best, methods — only how one man splits dragon hair and newt’s tail in our little shop.

My early lutherie and repair went slowly until an experienced luthier, a repairman in New York’s music district, helped me along. His “luthier’s gold” included explaining which measuring tools to have, and how to use them. Consistency is essential. You must strive to reduce error and deviation. To this end I have “master” reference tools in the shop: one ruler, one caliper, one flat surface, and my drawings. It doesn't matter if you use metric measurements or inches. Just pick the system you’re comfortable with, have good master references, and, stick with them. You’ll be successful. I’m metric because I tune Toyotas as well as 12-strings.

Measuring Archtop Musical Instruments

This is the first of three articles that take you from the basics of creating your own database of musical instrument measurements to applying what you have learned from those measured instruments while you carve top and back plates. In this article, you will learn to safely measure fine instruments. Article Two will describe plate carving, and article Three will describe plate graduating.

This article is dedicated to Bob Lundberg, from whom I first learned the basics of measuring instruments. He showed us how to set the bar high. — Chris Burt

Before you can build an archtop instrument based on an existing model, you need templates — at a minimum: a body-shape template, neck cross-section templates, and plate arching templates. You can’t carve something if you don’t understand it. If you are going to spend the considerable time that’s required to understand an instrument model, seek out the best. Measure several and keep detailed notes. If you take the time to compile a set of measuring tools and learn to use them respectfully and gently, you’ll be surprised to find how many people will allow you access to their fine instruments.

Chalk-fitting Guitar Braces

Chalk-fitting Guitar Braces

by Stephen Marchione

from his 2017 GAL Convention workshop

Originally published in American Lutherie #140, 2020



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.

Questions: Single Fretting Fixture

Questions: Single Fretting Fixture

by Tim Shaw

Originally published in American Lutherie #101, 2010



Mark French from West Lafayette, Indiana asks: Do people ever make a single fretting fixture and just pick off whatever section they need for a specific type of instrument? I started with a 25.5" scale length and added some frets to bump it up to about 34.07". It looks like I can use this set of positions to find fret spacing for everything from a bass to a mandolin.


Tim Shaw from Fender in Nashville, Tennessee responds:

You could also use this for both medium-scale bass, which is usually 32", and short-scale bass, which is typically 30" or so. Since Leo Fender had the 25.5" scale first, I don’t know if he actually “added” frets to come up with 34", but that was certainly possible on the prototype. The shorter Fender scales were also probably started by lopping frets off a standard neck.
