I have already ranted about wood on a couple of occasions but this week I was preparing cedar and I feel like there is a bit more to say on the subject.  My objective today will be to get all of you to stop using the the term “master grade” when talking about wood.  Here are some photos showing things to avoid in the woods we use for guitar-making.  Woods sold as master grade can often show these defects once they are planed or cut.  The best wood is that which, in the hands of a given maker, makes for the best guitar.  The only person who can choose the wood is the maker.

The first example shows a cedar neck which is lightweight and perfectly cut but has a pithy or stringy part which is very hard to sand and finish nicely (bad wood). Also I don’t trust it to be stiff.  Below is a fretboard which has a kind of ripple or flame which will make it very difficult to plane, once glued to the guitar before the frets are installed.  This is a very important step for allowing adjustment of the action and it is not a good time for tear-out.  The next picture shows some beautiful cedar but as the cut was started the tensions in the wood caused it to close on itself.  Not only is this dangerous on the table saw but you certainly don’t want to use this wood for a neck or a bar as it will likely deform with time.  Once cut, the stick will look like the photo which follows.

When cutting wood for bars or necks the cedar should be split to ensure maximum strength and stability.  Below is an example.  One thing you seldom run into when splitting cedar is a break like the one shown below, you sometimes get a hint from a dark line which shows where it will break.  Some say these are fractures caused by felling the tree; I really don’t know, but I can tell you that I always avoid using the piece if I see evidence of this.

The rosewoods too have their secrets, what some see as interesting or pretty grain others see as a tendency to deform or crack when we work with it. Flatsawn wood from very small trees, stump wood and severe run-out can all cause problems.  Ebony is the most prone to shrinkage of all the woods we use, a good reason to let it age as long as possible before using it on a guitar. Here is an ebony board which will be thrown out  because of deformation.  At some point before 1999 when I bought it it was sanded flat on both sides but as you can see from the picture the surface has lost any semblance of flatness.

The last wood I will mention is spruce as I think it is the one that gets the most attention from the “master grade” folks.  When spruce is cut it is not cost-effective to throw away the pieces that have run-out or are not riftsawn.  Quartersawing produces a few excellent pieces but as more cuts are taken the pieces are progressively more skewed with respect to the radius of the tree.   Splitting a tree that is twisted (European spruce very often is) doesn’t work very well for the woodseller either so run-out is very often present.  I think it goes without saying that dealers do not test for stiffness so basically the things we as builders value are not taken into account when wood is graded.  Master grade is assigned according to colour, grains per inch instead of the criteria that we use.  Below is a top that has a knot which was cut out but shows the shadow which also must be avoided. 

Once again, please trust your guitar-maker.  If you feel you must ask him to use the best possible woods don’t ask him to use someone else’s criteria to choose the wood.  He knows what works for him and he knows more about wood for guitars than you and the wood sellers will ever learn.

As I have mentioned before, bandurrias used to be as commonly made in Granada as guitars so makers had to be very familiar with them.  These days none of the good guitar-makers build them any more and you don’t see them taking repairs either.  A friend of mine inherited a bandurria from his grandfather and since it was made in a relatively well-known valencian factory in 1924 I agreed to restore it. Both the back and top had some minor cracks and the back had shrunk so much that it no longer rested on the reinforcements.  The choices for solving this last problem are reducing the perimeter of the sides or increasing the surface area of the back.  The bridge was coming off and when I took it off completely I saw that it had torn off once before taking a goodly amount of top wood with it and then been glued haphazardly back on.  Of course the frets were sticking out and felt like the neck was wrapped with barbed wire and the last of the problems rendering this instrument unplayable were the 12 wooden pegs! which were badly adjusted and cracked.   A challenge to be sure but I asked one of the makers here (José López Bellido) for some ideas and the specifications that a bandurria should stick to and it looks like it will be a musical instrument once again in short order.

As you may remember I attended the Guild of American Luthiers convention in July of last year and met some great people including two young men from Thailand who were in the final stages of developing a guitar case.  These cases are now available and I think they are worthwhile.  The ones I saw in the U.S. were prototypes but I think there have been very few changes.   I will be ordering some and can then decide if I want to use them on a regular basis.  Here is the link to the dealers page, note that Marshall Bruné is selling the cases in the U.S. and he and his father Richard have great things to say about them on their facebook page.

I am working to finish these guitars as soon as I can because I have to start on 4 Torres copies. The Torres model is what everyone seems to want these days.
These ones are going to Germany, China, Australia and Madrid. I’m taking a little longer to finish these because of other committments but I will be prioritizing the workshop again starting March 1st.

Biblioteca Musical Victor Espinós

Some things can only be found in the nation’s capital and this one was worth the visit. I was asked to do a technical investigation of a guitar housed in this library and travelled to Madrid with my measuring tools and cameras. The collection of instruments is very interesting but most of the pieces are not on display due to space constraints. With some luck, when the building works are finished there will be an exhibition space. The library was founded in 1919 and Victor Espinós, the man behind it and its first director expressed its principal objective thus: “… evitar que una vocación artística, o el afán de alcanzar un noble medio de vivir, puedan verse estrangulados por la miseria”. Loosely translated it means “to allow the underprivileged to aspire to an artistic career and a noble way of life”. In addition to the enchanting staff the library has another big draw, not only do they loan sheet music and books but also musical instruments! Andrés Segovia even donated a guitar to be offered on loan. Needless to say it was never loaned to library users. It was however used for at least one concert and sent out to exhibitions.

I won’t say anything about the guitar I went to examine but the information will be published this spring and I will have something to say about it here for sure.
