Cracked Plate

[Overs Pianos]

I was thinking the same as you Rob. This problem seems to be more 
likely to occur when the piano is subjected to higher daily 
temperature fluctuations. I've noticed a propensity for the Kawai 
name plates to develop filler cracks in country NSW, where the daily 
temperature variations are much more extreme than here in the coast. 
As Rob suggests, probably nothing to worry about.

and also slightly better stability at the break than most sawn-off 5' 
grand pianos. Simply because this piano has the break at D30/D#31, 
which is a much better location than the B27 placement of the great 
majority of the competition. The most ideal position for the break in 
the sawn-offs, in my opinion, is E32/F33.
