[CAUT] CAF

[Jeff Tanner]

Hi Susan,
Even if you did the rebuild, I wouldn't see it as your fault. I see it a lot around here. Both my mentors used to tell me that in the past, when you ordered parts from Steinway, you simply gave them the serial number of the piano, and the parts department would send out the proper parts for that instrument. I suspect technicians just trusted that.  I've seen it over and over again in Steinways rebuilt before the parts department started teaching what to do.  Ran into one at a small college yesterday, and when I touched the key, I knew what it was.  The shanks lay on the rest cushions to get enough blow distance, so you run into hammertails catching the backchecks, and the jacks have to be regulated forward to meet the knuckle, so they jam into the jack window cushions before the key hits the front rail punching.  The wippen/key does not "catch" or "cradle" the hammer/shank on its way down, it just drops with a thud, and the whole thing is just way too heavy.  If you've got a rebuild with all hornbeam parts, there's a high likelihood that this is what's in there.

The whole thing is correctable by ordering the pre-84 reps for the shanks, then you can recycle the hamburg wips on a rebuild with either NYI or Hamburg shanks.
Jeff

    Susan,
    What it sounds like you have is Pre-84 shanks and Hamburg wippens.  They don't work together very well.

  Yes, probably that was it. Luckily I was not the one who did the rebuild ... and I got it to work in the end, by the repinning and various other tweaks. It's now a second piano in a teaching studio, instead of the main one.

      This was an ex-teflon piano with some geometry problems. I had to tear some felt off the window cushions because some of the jacks were pressing into them. I got the jacks free but the note jamming problem was unchanged.


      In the end, I realized that the hammer tails were getting caught on the way up by the backchecks after the fast initial note and before the hard-played second one.
