[pianotech] cutting down a MH bridge

[David Love]

Defining tone is difficult at best.  Warm can also mean a bit stingy.  I
would prefer something a bit freer and I think the bridge and its size gets
in the way of that somewhat.  A bridge that lacks adequate height can also
be a problem (though at the other end of the spectrum) and I've seen
Steinway bridges that were very short at note 88 that benefited from being
made a bit taller.  OF course that requires some plate elevation changes and
such but it doesn't take much.  Ron's right, these aren't calculations, just
dead reckoning.  

 

Heavy dead plates are good things as are solid, heavy rims.  Higher tension
scales can be dealt with by properly designing the rib scale.  The bridge
adds some stiffness and unifies the assembly and distributes the load, but
it doesn't need to be that big, at least I don't think so.  I think the tone
will be improved: more expressive, wider range of dynamics, livelier and
freer sound.   But that's just my opinion, others may not agree.

Not really, Ron. (I should have put "calculations" in quotes.) What I meant
was "mental" calculations: figgerin', flossiphizin', stuph like that.......
(All I'm good for --- numbers scare me!) This thread just got the marbles
bouncing around... but not really knowing where to go....... 

So you have an ultra-dead plate, strung at a relatively high tension, over
fat, impedance inducing bridges, on a CC board, on a beefy case....... and
it all somehow adds up to that warm, rich, Mason tone....... (albeit with a
board that splits like crazy, eventually) and the goal here is to improve on
that. (Which I'm certain can be done!) Hmmmmmm... I'd just really want to
contemplate all these complementary and countervailing (some, perhaps, by
design) factors, before I tried anything...

You overestimate the scope of the calculations.
