[pianotech] Lyre Damage

[Greg Newell]

I have! I've seen drop screws broken off. Admittedly there wasn't much of a
gap between the screws and the block in the first place but that's no
excuse. Even if this weren't the case the rounded over edges of the lyre
bottom is just plain negligent IMHO.

Quite so. I'm curious though. Have any of you found action 
problems you could attribute directly to setting a piano up on 
the lyre? Any actual evidence of key bed damage from this? I 
never have, but there are still an infinity of places I 
haven't been. So I was wondering if this is real, or yet 
another of those "intuitive" things. I know broken lyres and 
crushed corners on bottom plates are real, I'm just wondering 
where all this concern for the key bed comes from.
