I enjoyed the revealed beauty in these 98 year old keys. In preparation for installing new keytops, I cleaned the key set, and removed 1.2 mm from the top and front of the keys. The removal of this precise depth of wood preserves the action geometry of the key when installing new keytops. (The original keytop was 0.9 mm; the new plastic keytop is 2.1 mm; 2.1mm – 0.9mm = 1.2mm )

I love pianos: as a musician, as a technician, and as a craftsman. The joy of my profession is to bring out the best in every piano I encounter.
He who works with his hands is a laborer.
He who works with his hands and his head is a craftsman.
He who works with his hands and his head and his heart is an artist.
