It's a shocker, I know, but there are actually other pianos than 
Steinway out there, with plates far more heavily built than the flimsy, 
squirrely D plate that makes a vanishingly small pitch change such a 
futile adventure in tail chasing. I never actually weighed them off, but 
my back and chain hoist tells me that the a Baldwin SD-10 B plate weighs 
SUBSTANTIALLY more than any Steinway D ever aspired to.

Another passing observation from the cheap seats, to aid (complicate) 
the plate hoist calibration process.
