Gluing tentellones

on December 30, 2016

It would seem to me, there is really no advantage (sound wise) for the two chevron braces at the bottom of the soundboard. Oribe does basically the same. Why not just extend the seven fan braces all the way to the bottom edge of the soundboard? I would think, structurally, it would be just as effective. Oribe told me the traverse bar. at an angle, is to tighten up the treble side of the soundboard.

I find they add more clarity to the notes, but I actually prefer what Hauser ii and iii have done and that is to get rid of them and the notes blend a little better. Hard to describe it, but I have the sound in my head. IMO the Oribe bracing is achieving something different.  I have tried that bracing and find that it makes the vibrating surface smaller which is a good thing. Impedance matching. Nylon string guitars have the right volume of air but too big a vibrating surface. By making the vibrating surface smaller you match the string output. Dammann makes the inner vibrating surface smaller for impedance matching as well but he uses large tentellones

This is what Duane Waterman, Tucson, Arizona luthier had to say and a photo of one of his soundboards. 

 

 

“You know, there are many Spanish builders of the last century – and many more of more recent times – that do just that. Almost all of the current day Granada builders do not have the “V” chevrons. mostly 5 fans all the way to the bottom edge of the top. Others, and myself, have used systems that use chevrons/fans only on the treble side, supposedly to make that side “tighter”. See attached photo.

I am certain that some of the builders believe that these lower limiting braces have a sound and structural function, but I think the whole top – and tone – is looser when the fans extend to the ends of the top.

Duane Waterman”
