Steinway hammer alignment

[Paul]

Mark
I just did one of these. I added a shim behind the stop block on the bass
side of the key frame, made minor adjustments to align hammers to strings,
took up the lost motion of the una corda pedal, reset the stop screw on the
treble side of the key frame. Test all keys with una corda pedal depressed.
There is a tendency for some of the keys to pick up an adjacent damper
lever.
