Fw: Steinway D key levelling (Hamburg model)

[Michael Gamble]

Hello Cy Shuster.
I have in front of me the S&S Service manual. re: Key Leveling it says: "The
process of leveling the keys now follows. At the factory the end keys are
set at 63mm on models S - B and at 65mm on models C - D (upper edge of key
bottom to lower edge of key covering). In the non-depressed state, the
sharps should project 12mm above the naturals. By means of a straightedge
(rule) extending to the lengtrh of the keyboard and revealing 2mm mid
arching, the keys are aligned exactly underneath the straightedge without
any clearance whatever. This ist done by inserting paper washers or shims
underneath the keays at the balance pins. In the event of major adjustments
proving necessary, the action shopuld be unscrewed and the keys weighted by
means of a steel rule which is used to offset the weight of the hammer and
support and which can be applied or lifted off easily and quickly while the
key is removed." end of quote. I used to use car wheel balancing weights to
each key at the check block wire until I got a set of the real thingy. I
like the "this ist done" - half Deutch half Englander. The first half of the
book is is German and I can quote that too but nicht understanden! :-)
