I meet Samir advice. Don't hesitate to sand down your soundboard. Then it is a matter of taste, maybe you wish to achieve a stiff soundboard.
if you want something more reactive, go down in thickness. It depends also of the quality of the wood of the soundboard.
As an exemple, for mine I went to 1.8 mm .. but that is a short range to make the final cleaning of the soundboard once the work finish
For the rosette you have time, keep it open. It s even an advantage. Maybe at the end you wish to correct some things on the braces before gluing the
rosette. Some makers do that sometimes.
Keep on the good work, il looks great |
