Ed Glass Posted May 2, 2014 Report Share Posted May 2, 2014 Violin Top plate Before ff and bass bar: weight gm.s mode 2 Hz mode 5 Hz 69.5 170 337 After ff and partially (?) carved BBar: 71.2 182 339 Have observed that trimming distal thirds of Bbar RAISES Modes 2 and 5 (probably d/t reduced mass), and that carving/trimming middle third LOWERS modes 2 and 5 (probably d/t reduced central stiffness). But where/how to carve Bbar to bring Mode 2 down more, without affecting Mode 5 much ? And similarly, how best to preferentially affect mode 5 rather than mode 2 ?
