Letter: Use Any Wood You Like

Letter: Use Any Wood You Like

by John Calkin

Originally published in American Lutherie #25, 1991



Dear Tim,

In 1981 I bought a new Alvarez-Yari 6-string, with laminated rosewood back and solid spruce top. Lots of guitars sound as good, but hardly any sound better. Lots of guitars are as playable, but very few play nicer. I’ve worked on or played dozens of high end, exquisitely made guitars and a bunch of vintage pieces, and not one has ever blown me away.

Early in my career I helped do sound at a local folk benefit. Lots of fine talent turned out, sporting a number of classy guitars. But a low-end mahogany Yamaha blew them all away, no contest.

Letter: Veneer Backing Boards

Letter: Veneer Backing Boards

by Lloyd Zsiros

Originally published in American Lutherie #30, 1992

 

Tim,

The wood supplier I deal with for almost all of my materials (A&M Wood Specialty in Cambridge, Ontario — a frequent advertiser in American Lutherie) sometimes gets in quantities of backing boards. These boards are a byproduct of the veneer industry. As most of us know the veneer industry manages to get hold of some of the finest and most desirable logs of various species. These logs are then cut into manageable sizes, if necessary, and clamped into a massive carriage assembly which then moves the log past a stationary knife, neatly slicing off uniform thicknesses of veneer. The carriage assembly used large steel teeth to grab the log and the knife can only cut so close to these. What’s left is a piece of wood usually anywhere from about 1/2" to over 1 1/4" known as a backing board. Many of these are perfectly quartered and quite wide. They can often be purchased directly from the veneer mill or from suppliers like A&M at extremely attractive prices. I have obtained walnut, cherry, and beech this way at a fraction of the usual cost. The boards are often just thrown outdoors usually in the open so they may not be very attractive on the surface but I have obtained some of the nicest walnut I’ve ever seen from these. I’ve noticed some favorable comments in American Lutherie about cherry as an instrument wood. This is a good source for nice wide quartered cherry. Although I’ve never used this on a guitar I do have some 1' long, 20" wide, 1 1/4" thick quartered cherry I obtained a few years ago for $2 a square foot I’ve been saving for something special. It could be worth a try! Oh, and a word on A&M Woods. As they are an advertiser in American Lutherie, you may be interested in knowing I have had nothing but great service from them. They have been my primary source of materials for over 10 years and I can’t say enough good things about Andy and his staff at A&M.

Letter: Osage Orange

Letter: Osage Orange

by Rion Dudley

Originally published in American Lutherie #36, 1993



Dear GAL,

I’d like to express my appreciation to all who have contributed to the GAL over the years. I especially want Rick Turner and Harry Fleishman to know that their knowledge, opinions, and ideas have been a great help to my lutherie work. The recent publication of the information on alternative lutherie woods has inspired me to share my own experience.

A number of years ago (longer than I wish to remember), Ted Davis wrote an article about his experience using Osage orange for a small-bodied Martin-style guitar. I read that article with great interest, and purchased some Osage orange that was nearly quartered from Gilmer Woods. The wood sat around my shop and collected dust for quite awhile.

Letter: Crystals in Wood Cells

Letter: Crystals in Wood Cells

by Bill Moran

Originally published in American Lutherie #35, 1993

 

Dear Tim,

In American Lutherie #33, Nicholas Von Robison has sent a signal, maybe unknowingly, that there are scientific activities related with lutherie that are not well known or yet fully appreciated as part of quality instrument assessment. I am referring to the growth of crystals in the wood parenchyma cells. Concern over acid rain also leads me to openly ask, what are the effects of acid rain on the crystal development and their performance, and who is doing the studies, if any? I hope this letter will catch the attention of the Wood Chemists and the true wood anatomists amongst the membership and that they also will respond to my questions. Mr. Von Robison appears to be well informed on wood chemistry and I hope he will publish related data or suggest sources for the details he has on these subjects.

Microphotographs of wood samples taken under the electron microscope has shown that crystals are present, and separate spectrum analysis have been made of their mineral content. Information is sparse but I believe important since I am referring to the crystals in spruce and maple woods, although I do have reports describing the crystals in a number of other woods. This study includes unique measurement instrument construction, computer programs, resources, and time.

I will be pleased to correspond with anyone pursuing study related to material in this letter.

Letter: Engelmann Spruce

Letter: Engelmann Spruce

by Jan E. Callister

Previously published in American Lutherie #53, 1998



Dear Tim:

Just a few comments on Don Musser’s interesting article, “Rocky Mountain Tonewood Alternatives” in AL#51. Years ago when I was cutting Engelmann spruce and trying to market it for soundboards, I often found large logs of Colorado blue spruce (Picea pungens) in the yards of logging mills. These trees were called “swamp” spruce by the local loggers since the trees apparently grow in high meadows with an abundance of water. I found the annual rings to be much too wide for guitar soundboards. I have since been told that this may not be a problem for luthiers who build cello or bass viol. Don Musser probably has a much better chance of finding ideal blue spruce in Colorado where blue spruce is much more abundant than in Utah.
