I am interested to know what's the best shape to apply to grand piano soundboard when gluing ribs in bed tool, is it like a cylinder shape = where bridge is on the top, or may be a sphere shape like upright where the = top is on the middle of bridge ? or something other ? Also, what's the best curve amplitude in this case ?? and for to finish, the best downbearing map from note No 1 to 88 ?? . Many thanks for your help..
