fallboard vs. keytops

[David Ilvedson]

Key height to spec at the extremes?   Keys look correct to keyslip?   i.e. key front looks like a square...key pins up into the key mortice a bit when key at rest?   Is this a Japanese piano?   if so not likely a manufacturing error...really does sound like a bedding problem.   A quick look at the glides would show if they were turned down abnormally...Does the fallboard have a normal gap at the top when closed?   How do the cheekblocks align with fallboard?   Keys much higher than the cheekblocks?   Check blow distance...shanks just above the rest felt...normalcy...
