The Timber Yard
Timber choice is a pretty hotly debated topic amonst guitarists and luthiers with claims about the different tonal properties of different woods. Certainly if you are building an acoustic guitar the wood will make a big difference to the tone and resonance of the sound, as it is the resonance of the wood wich amplifies the vibrations of the strings. Electric guitars are different though, the strings are amplified electronically from signals generated by magnetic pickups. Although many a forum discussion has heated arguments about the different kinds of timbre (i.e characteristics) of the sound different woods make, for instance alder and ash are said to be brighter with mahogany producing a darker sound, the concensus among most luthiers seems to be that it really doesn’t make too much difference at all, excpect for maybe sustain, as the bulk of the sound is generated from the pickups and the amplifier. It is for this reason that in solid body guitar building, the visual characteristic of the wood are the most prized.
So with this and the dimensions in mind I went to a local fine timber yard to see what wood they had in stock. I didn’t want to spend a lot of money with this being my first ever guitar build, so I bought Kauri Pine, which I had planed down from 4cm to 2.5cm depth, and to put on top Victorian Ash which was 2cm thick. Neither are wide enough to cover the entire width of the design so I will have to laminate (glue) two pieces together, I will also have to of course glue the ash onto the pine. Below you can see a picture of the pine before and after cutting.
Something which I hadn’t considered was where to join the pieces of wood. Being a bit more practical and possesing a considerable amount more common sense than myself, my dad reccomended that I join the top piece of wood with equal size halves and the bottom piece with unequal size halves, or offset if you like.
The reason for this is because of structural integrity. Doing it this way avoids the two vertical joins from my different pieces lining up on top of each other when I glue them horizontally, as in one on top of the other. This way the guitar body will be stronger because it will be less likely to simply snap into two pieces down the middle because the two layers of wood will support each other. The last thing you want is your guitar falling apart!
