[CAUT] Imperial with breaking bass strings

[Overs Pianos]

Hi David,

Its not uncommon for Imperials to break bass strings, since their 
basses are strung at quite a high percentage of breaking strain. For 
example, the note which is the equivalent of C4, on a normal 88 notes 
compass, is strung with 23 g core wire (1.3 mm diameter) at a tension 
of just over 180 Kg. Any sloppy tuning hammer technique over a number 
of years will result in breakages at such tensions. Even with care, 
anything can happen after the first decade.

Its time the Imperial you saw yesterday was restrung.
