this is a small deviation from how I normally brace the tops, namely that I added a cross grain brace to help support the dome in the top. That brace is capped with carbon fiber to give it additional strength because it's so short. The height of the brace is such because there are additional structural braces inside the bandura that run vertically to resist the pull of the strings. A tall brace will interfere with these braces. I recently posted some questions to the OLF regarding some bracing ideas and that discussion can be found here.
Some specs from this top:
Weight before bracing: 278g
Weight after bracing (not final): 368g
Thickness: ~0.128"
Guitar makers will notice that this top is almost double what a guitar top weighs. Considering the additional load that a bandura top takes it's not surprising. Tapping produces a decent tone but nothing like what you hear when tapping a guitar top. Unfortunately, I'm not sure that anything can be done about this because of the huge load on the bridge from all of the strings. The good news is that this won't necessarily mean that the sound will be bad. My prior instruments have bracing that's just as heavy or heavier than this one and sound pretty good.
