Amigos:
Michael McBroom me ha enviado amablemente información sobre sus medidas de construcción de las guitarras de 10 cuerdas que os pongo a continuación. Están en Inglés pero así cumplimos dos objetivos: aprender idiomas y lutheria de 10 cuerdas al mismo tiempo.
> Typically, a 10-string will have an 85mm nut, and will be 100mm wide
> at the 12th fret. The string spacing I use is 8.5mm at the nut and
> 11.5mm at the bridge saddle. I design my bridges so the saddle length
> is about 115mm. Overall bridge length varies depending on the maker.
> 230mm is a good in-between compromise. You can go with the standard
> bridge width, which is typically between 28mm and 32mm. I prefer a
> narrow bridge -- about 26mm or so. Don't make the bridge too big,
> though, or you will kill the sound.

Espero que os sirva la información y saludos,
Manuel.
