Precision Woodworking – 1914 Kimball keys

September 9, 2012

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 )
