[pianotech] Fwd: Bummer Bass Bridge

[Terry Farrell]

Hmmmmm, is this a test? That's funny - I can only picture you as the  
teacher standing in front of the class asking that question - one that  
you already know the answer to!

So, okay, I'll bite:

Interesting question. I would presume it would be most likely related  
to the grain angle in the bass bridge - that a weaker orientation  
lines up more favorably with the speaking pins and cracks more easily.  
But come to think of it, when I have seen a cracked bass or high  
treble bridge, it is almost always the speaking side that cracks more.  
Could it be that the string doesn't tend to render through the bridge  
pins completely and more tension is on the speaking side of the string  
and thus more pressure is applied to the speaking bridge pins?
