Heat Pressing

Heat Pressing

Originally published as Guild of American Luthiers Data Sheet #43, 1977



Heat pressing is the art of forming wood to a new and permanent shape with heat and pressure. With practice, it is an effective method of action adjustment when extreme measures are necessary; when time or poor construction methods develop a problem, has a fair idea of what a “good” action is, and is familiar with such terms as “action”, “buzzing”, “truss rod”, and the numbering system of frets, etc. The term “buzzing” assumes that the string is plucked moderately hard. Applied to guitars, the art of heat pressing is to create the optimum neck shape for a fretted, plucked string. This means a buzz-free, even action over the entire length of the fretboard. Part One explains what that neck shape is, clears up some of the fallacies and old wives’ tales on the subject, and points out some common neck problems.


The Bow

Basically, a plucked string travels in a bow, like this:

Brazilian Guitar Makers

Brazilian Guitarmakers

Originally published in American Lutherie #33, 1993 and Big Red Book of American Lutherie Volume Three, 2004



The guitar has been the main musical instrument in Brazil since it was brought by the Portuguese colonizers centuries ago. In those times, Baroque guitars were the most common string instruments. They had five courses of gut or wire strings. Since then it hasn’t changed much, as we can see in the “Brazilian viola” which is used for a kind of Brazilian country music called musica sertaneja (countryside music). The shape of the soundbox of this viola today resembles more a small classic guitar. Unfortunately there are very few records of those times, making it difficult to make a better study of those guitars and their makers. It’s known that most of the instruments were made in Portugal, Italy, and France.

The first decade of this century brought three immigrant families from Italy: the Gianninis, the DiGiorgios, and the DelVecchios. These families were luthiers in their country of origin and later they founded the main Brazilian guitar factories which became the backbone of Brazilian-made guitars for nearly eighty years. They made mostly classic guitars and some violins, along with Brazilian violas. They also made mandolins, first with vaulted backs like lutes and later with flat backs, which are used to play choro music.

What You Should Know About The Hardanger Fiddle

What You Should Know About

The Hardanger Fiddle

by David Golber

Previously published in American Lutherie #36, 1993 and The Big Red Book of American Lutherie, Volume Three, 2004



Someone has walked into your shop with yet another weird instrument. This time, it’s sort of like a violin, but it has a whole lot of pegs, the top is carved funny, it has pearl and bone inlay, and it’s decorated with flowery drawings. He says his grandfather brought it from Norway in 1890, and he wants you to put it in playing condition.

Well, it’s a Hardanger fiddle (hardingfele in Norwegian). The instrument originated in the area around the Hardanger fjord, whence its name. It is distinctly Norwegian; in fact, it is played in only about a quarter of Norway, the western and south-central areas. The oldest instrument found has a date of 1651. The musical tradition is still very much alive, and continues unbroken up to the present.

Beginning in about 1850, there was an absolutely enormous emigration from Norway to America — something like a third of the population. Those who played fiddle of course brought their fiddles with them. In addition there were tours by professional players who performed for their emigrated countrymen and then returned to Norway. But the instrument and the music died out in America. The children of the immigrants rarely learned to play, and father’s fiddle lay in its case in the attic, or was hung on the wall like an icon of a lost era. Now there is something like a revival here in America, not only among the descendants of the immigrants, but also among those not of Norwegian ancestry who have discovered the music.
