Good morning everyone, this is my first time writing, compliments on the site.
I have a problem with my upright piano, a Steinberg Farfisa that I purchased last year; probably due to moving it to a different location, after some time some keys stopped playing (they seemed to go slack without weight). Thanks to your lessons, I managed to understand that, in these keys, the escapement lever, after pushing the capstan and consequently the hammer, was unable to return to its resting position under the capstan, but instead rested on the front part of the capstan, and consequently when the key was pressed again, it rose without resistance.
Very cautiously and thinking three times before every operation, I managed to extract the entire "mechanical action frame" from the piano and I disassembled the mechanism of one faulty key, beastly!
Having the mechanism in hand, I noticed that the problem lies exactly in the pivot of the escapement lever which has become slightly stiff (at first I thought it was the spring, but no); in fact, as I read here on the forum, the escapement lever without a spring should move freely even just under its own weight, but instead it moved with difficulty, so I "delicately forced it" a little until it started moving freely again—a somewhat unprofessional solution... I imagine, but when I reassembled it, it worked correctly.
I read here that you should never lubricate the pivots and I didn't do it; how can I therefore definitively resolve this problem over time, which was caused, I imagine, by some humidity?
Hello everyone and thanks in advance.
Simone.
