Stienway(Steinway) d-rolled bridge saga- report

Hello List
This "caveat emptor" business is NOT something I would expect to be hurled 
at me by such a manufacturer as S&S. I bought a second hand year old Ford 
nearly two years ago. There is a "three year warranty" from Ford still in 
force and when I discovered rust on two of the doors Ford immediately called 
in the car, replaced the doors, sprayed in the paint-work, cleaned and 
polished the car and gave me a "courtesy car" whilst it was done (one week) 
as well. No cost to me. Now that is what I call committment. When we had 
trouble with a Grotrian Steinweg small Concert Grand, Grotrians took the 
piano back to Germany, fixed the problem to our satisfaction and supplied us 
with a "courtesy piano" whilst this was done. Again at no cost. Do we not 
expect the same from S&S - particularly where one of their "flag-ship" 
instruments is concerned? Or am I not reading this "posting" correctly?
Regards from a beautiful sunset over the Sussex Downs Village.

>>>Hello
>>>
>>>     Dave Renaud here, Ottawa-Gatineau, Canada.
>>>
>>>     One of my clients is the  Quebec Conservatory in
>>>Gatineau Quebec.
>>>
>>>      They have a new D  you are likely aware of. It
>>>was in ......cut...............
>>>
>>>      I  have a few observations that should be
>>>investigated.
>>>
>>>Minor......     There were very large 2-3 inch long
>>>shards of glue where the soundboard meets the belly
>>>rail.  Some of these thin shards from oozing glue
>>>(I saved some, could take a pic.), were lightly
>>>touching/buzzing against the board. I cleaned this up,
>>>  It eliminated some buzzes and did take time to
>>>troubleshoot.........when all else was eliminated, I
>>>thought it had to be the glue joint along the rim.
>>>
>>>Major......     The bearing on the back of the bridges
>>>is high, the bearing on the front(speaking side)
>>>much lower. As much as 20 at the back and 0 at the
>>>front. This is all over, on both the treble , and bass
>>>bridge. I was motivated to measure because a buzz on
>>>the backscale could  not be eliminated without pushing
>>>the string down on the backsacle plate. This string
>>>would not seat on the plate due 0 bearing over the
>>>plate, This lead be to wonder if Perhaps the back of
>>>the bridge was high. It is, and the front is
>>>low, string travelling downhill to the speaking
>>>length.
>>>
>>>These measurements were made with a Lowell gauge.
>>>
>>>I followed up by having xxxx from xxx measure with a
>>>bubble gauge. He had negative measuments on the bridge
>>>cap angle all over the piano as much as negative 18 in
>>>places. I then had xxxxx look at it and confirm the
>>>same thing.
>>>
>>>     The strings should travel "uphill" to its
>>>termination point at the speaking length.
>>>They are travelling downhill to the speaking length.
>>>
>>>     Marcel came down from Quebec city, and spent a day
>>>seating and mating strings, did a wonderful job, and
>>>the piano was much better.
>>>
>>>     With the negative slop to the bridge nothing will
>>>stay seated for long.
>>>
>>>    What believe has happened with this piano is
>>>technicians arriving for a day, with a program
>>>in mind to treat normal problems. Indeed, they find
>>>strings that need seating, and  hammers that need
>>>mating....normal.....and proceed to fix it.
>>>
>>>   But on this piano, the poor seating, and string
>>>mating is NOT because it was neglected, or not
>>>maintained properly, and not because needs proper
>>>concert service. We can do that. It is a recurring
>>>symptom of the negative bridge cap angle.
>>>
>>>   The opinion that I am hearing suggested from techs
>>>is the soundboard at the front of the bridge may have
>>>collapsed somewhat. Hmmm...that belly rail that
>>>should supports the crown and all those oozing glue
>>>shards at that very joint. Could this mean something
>>>related. What does those shards suggest in the
>>>manufacturing process. Just too much glue? not
>>>securely glued  down at the belly normally? Just not
>>>cleaned up? Just thinking out loud ...any thoughts
