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: Remembering Robert Bouchet

Letter: Remembering Robert Bouchet

Dear Sirs,

Coming back to Europe in 1973 from America where I had been working for some years, I had the nasty surprise of opening my guitar case in Paris, to find my Contreras flamenco guitar broken. One of the components of the heel had become unstuck. Cracks were wide open on the ribs on each side of the neck.

In those times I used to keep my guitar with me in the cabin without having to pay for an extra seat. But that day they took my guitar just before boarding and put in the hold. I thought I was prepared for all eventualities: I had made a rain cover for the case and put polyurethane under it. I had pieces of foam in strategic places inside the case to keep the guitar steady. Well, apparently that was not enough. I was pretty sad when I saw the damage.

Letter: Remembering Robert Lundberg

Letter: Remembering Robert Lundberg

Dear Jonathon:

I has been several weeks since Historical Lute Construction by Robert Lundberg arrived. I wanted to really absorb it before showering you with well-deserved praise for your great work of lutherie documentation. I have read the whole book several times. It’s a great work.

Bob built my two lutes during his early period, while I was a student in Basel, a time which also saw the beginnings of my attempts at lutherie. I once played my Bach suite program with Susan at Reed College in Portland, partly arranged by Bob’s first wife Ellen. One of the works I played that day was my own Tombeau for Glenn Gould, a piece for lute and harpsichord. Bob liked that, I remember. We had borrowed a Flemish double by Byron Will for Susan to play, and he and Byron seemed to get a real charge out of a couple of very determined musicians trying to play in a cafeteria full of hungry students on a Sunday evening, with the smell of frying fish heavy in the air. The 300 or so students were perfectly behaved, as they listened to a French Suite, Prelude Fugue and Allegro, the Chromatic Fantasy, and works by Weiss and Hagen, played on some of the best early instruments made by American crafters. But they seemed not to notice, as if this were normal, or perhaps such a smoothly executed event that it was no more to them than a violin and piano recital. Bob was happy to hear his own lute played in such demanding circumstances. My last memory of Bob is of his kindness, his gentleness, and his understanding of my struggle with the hardest music anyone could ever write for a lute.

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.

Letter: Remembering José Rubio

Letter: Remembering José Rubio

by Keith Watson

Previously published in American Lutherie #79, 2004



Dear Sir or Madam,

AL#65 was recently passed on to me by Jack Spira of Melbourne, a builder of guitars and related instruments. For several years I had been attempting to find the whereabouts of David Spinks (aka José Rubio) in order to renew a friendship that we had in London in the mid-’50s. I had come to London from the north to study flamenco and wood carving and had started my classical guitar tuition in with Alexis Chesnicov. I then went to Paco Juanos who gave lessons in Hampstead at a coffee house called El Serrano. It was there I met David.
