Why some Bechstein plates have cracked, was Re: Old Steinways

[Calin Tantareanu]

Those articles are really interesting. They also give a good explanation on 
why some Bechstein plates are cracked. The reason seems to be an improper 
fit of pinblock to plate, but not necessarily as a fault of the original 
installation, rather because the wood of the pinblock has compressed in time 
and allowed it to rotate slightly, thus stressing the plate and causing it 
to crack.
