benros -> RE: my first flamenca build (Feb. 17 2019 11:32:08)

thanks despiado! So, yesterday the final moment was there, i strung it up, tuned it and everything was very promising: punchy, loud, fast response, even across the board, action at the 12th fret 3,2mm and 8 mm at the bridge, 9mm at the sound hole (and still room to adjust and go lower) ... everything seemed like i wanted it to be. But after 30 minutes under tension, i realized that the soundboard had collapsed, better said: it sunk in some 1,5-2mm, so that it had 9,5-10mm in the middle between soundhole and bridge, 9 at the soundhole and 8mm at the bridge. What a devastating experience!!! After releasing the tension the soundboard came back and is now nearly flat between bridge and soundhole (where it was domed all the way to the middle of the soundhole before). So, obviously i have gone to far and over the red line in terms of structural integrity of the soundboard. Besides that, i drilled the holes in the bridge too narrow (i took the dimensions from a technical drawing that was not correctly dimensioned), so that stringspacing is something around 55mm, which i know, is much to narrow, but curiously felt not too bad for me, since picado and arpeggios are much easier to play. anyway, that's just on top. before i deal with this issue, i have to solve the more serious one. So i have to correct myself: i made some serious failures. When i handle to get over the paralyzed mood i'm in right now, i have to take action to stabilize the pointed region of the soundboard, which will be kind of a open heart surgery and way over my abilities. so take this as an S.O.S-call: I need to decide, what to do and how to do it and could need some professional help to consider both of these questions (you can see my soundboard on top of this thread). so, any recommendations?
