Rosewood and Ebony Shortage

Rosewood and Ebony Shortage

Originally published in Guild of American Luthiers Quarterly, Volume 8 ,#1, 1980



Note: Mr. Larson is President of VIKWOOD LTD., a large American Importer of rosewood, ebony, and spruce. He is a member of the Forest Products Research Society and has served as Tropical Woods Committee Chairman and is currently on the Mid-West Board of Directors.

Innumerable articles have been written during the past year concerning the extreme shortage of rosewood and ebony supplies for the luthier trade. Having just returned in November from my second trip to India in 1979, I am happy to report that the situation is not as glum as it appears from the articles in the trade journals. There are adequate supplies of rosewood and ebony logs and a large number of competent log converters who can supply dimensioned items such as backs and sides, fingerboards, and even machined bridges in goodly quantity.

Early Engelmann

Early Engelmann

Originally published in Guild of American Luthiers Quarterly Volume 10 #3, 1982, updated 1993 and Luthier Woods and Steel String Guitars, 1997



In 1975, while completing my third guitar, I became very interested in the interplay of the different woods and their significance in the construction of a guitar. Most beginning guitarmakers, I am sure, have had the same interest. However, I questioned the use of European spruce as the most esteemed tonewood. Why didn’t our own domestic spruce wood have the same qualities? I began researching the literature to gain information on our own domestic spruce and its use for musical instruments. I found some references concerning Sitka spruce, mainly short paragraphs relating to tonal characteristics of violins. I couldn’t help wondering if the Engelmann spruce from the forests on the mountains just east of my home near Salt Lake City might have possibilities for guitarmaking. My research revealed hints that Engelmann had been used successfully by a few violinmakers as far back as the 1900s. A local industrial arts professor noted for his knowledge of woods, however, told me that Engelmann had no merit as a tonewood. Undaunted, I continued my research and found positive confirmation of Engelmann’s tonal value from Peter Prier of the American Violin Making School in Salt Lake City, Sam Daniels from Jerome, Idaho, and some records of R. Peter Larsen who had built over 100 violins in the late 19th century and said Engelmann was “superior in tone to Italian wood.”

Prepping Rough Planks for Solid Bodies

Prepping Rough Planks for Solid Bodies

by John Calkin

Published online by Guild of American Luthiers, October 2021

 

There are plenty of places online where we can purchase prepped electric guitar body blanks. But who can refuse free wood when it is offered? Several rough planks of 2"×9"×12' poplar came to me out of the blue. They had been painted on two sides, but so what? They had spent years in a dry barn. I cut them down to 6' to fit them in my little pickup truck, hauled them home, and stored them in my mower shed for two more years.

I have been working on electric ukuleles, mandolins, and mini guitars, and that is where the poplar is destined to be used.

The first step was to cut a plank into 15" lengths using a sled on the table saw. Though it looks like the plank will be run against the fence, there will be plenty of clearance after the cut is set up.

Two pieces sat evenly on the saw deck so I proceeded to run them through the drum sander, first the humped side and then the cupped side.

One edge was sanded flat (but not perfectly) on the 6"×48" belt sander in order to run it evenly against the table saw fence while the other side was trimmed clean and perpendicular to the faces. In this photo, the second edge is about to be trimmed.

That's as far as I will take them for now. They are shy of the 1 3/4" thickness used for most Fender electrics but plenty thick enough for smaller solidbodies. When the time comes, the shorter length will be sliced up to widen the longer piece as necessary, making the bit still covered in red paint irrelevant.

Once joined the blank may be thinned even more to accept a top of figured wood, but that lies in the future. The three blanks off the board that rocked too much on a flat surface would still rock after thickness sanding, so they will get a slightly different treatment later. ◆

’Way Down Upon the Amazon River

’Way Down Upon the Amazon River

by John Curtis

Originally published in American Lutherie #10, 1987 and Big Red Book of American Lutherie Volume One, 2000



There are many South American exotics that are perfectly viable species for instrument building. It’s hard to get luthiers to go along with that, however. Everyone wants perfectly-quartered Brazilian rosewood.

The reason I mention alternative woods is that the true Dalbergia nigra, the Brazilian rosewood that luthiers love and would sell their cars and dogs for, is getting to be very hard to find. We at Luthiers Mercantile found this out the hard way a few years ago, in much the same way that the Martin Co. did. You have to pay for the wood up front, which puts you at great risk; you just have to trust the person you are buying from.

Building the Tar

Building the Tar

by Nasser Shirazi

Originally published in American Lutherie #10, 1987 and Big Red Book of American Lutherie Volume One, 2000



The Tar (meaning “string” or “chord” in Farsi) is a classical Iranian stringed instrument which has two body cavities and is played by plucking the strings. The two sound chambers are covered with two separate skin membranes. The instrument’s six strings are tuned in pairs and are played with a brass plectrum inserted in a lump of beeswax. The tar is an integral part of classical Iranian music ensembles, along with the kamanché, setar, ney, santour, tomback, and oud.

The soundbox is extensively made of mulberry wood, although other woods such as maple, walnut, and apricot have also been used. Use a well-seasoned wood with no knots, checks, or other wood defects known to luthiers.
