[CAUT] soundboard "stress test"

Well actually this fire restoration person was an RPT who happens to
specialize in this area including full restorations.  I think the source is
fairly reliable recommended to me by several different people on this list.
He has taught several classes at the national convention on the subject.
So while I agree that your standard fire cleanup guy probably doesn't know
pianos I don't think this was the case here.  As I mentioned, I am no expert
in this area but the information passed on to me was that once the flames
come in contact with the case and especially the soundboard that attempting
a repair by simple scraping and cleaning probably isn't sufficient.  I
would certainly guess that in order for the soundboard varnish on top of the
board to bubble from heat generated from underneath that the integrity of
the board would be in question.   If it were me, I would be trying to avoid
the scenario of making an estimate for the simpler clean and repair, having
an insurance company make a settlement only to find that the board fell out
of the piano, the ribs fell off and it started crumbling later.  Not a good
situation.

Hi David,

 

I would not take what fire restoration people say as the final word on many
things. I have run into them in my work on some pianos that they said were
way beyond repairing and they were pretty far off the mark. I have two
pianos that are still going strong over thirty years after they were damaged
by fire. One of them had the corner of the piano burning when the fire
department arrived. You would never guess that anything happened to these
pianos. I have found, also, in my work in the fire department that there are
times when the restoration "experts" had written furniture and whole housed
off that are still being used. I was asked to speak to a group of insurance
people once about fire and water damage to pianos. I had found out by many
of these people that it is easier to just sign things off than to repair
different articles. I am no expert as far as fire restoration is concerned
but I have found by experience in both the piano and fire se rvice that many
of these people take for granted whatever is told to them when they take
their training. I have run into some very knowledgeable people in the fire
restoration business and some who have no clue as to the real world. Best to
you.

 

God bless

The issue here is not so much the finish but what happened to the panel and 
the glue joints when the fire toasted the board down to some very low EMC 
and heated the rib/panel glue joints.  While I am not an expert in this 
area, my recent conversations with fire restoration individuals suggest that

once the flames actually touch the surface (especially the soundboard 
directly) the potential for failure increases exponentially and the piano is

generally written off as a total loss unless complete remanufacturing is 
planned and justified by the piano's inherent value.  While there may be 
some instances of "survival" the acoustical properties and longevity of the 
glue joints (this can be in the rim and support beams as well as the panel) 
come into question.

Our restoration shop just received a piano that's been subjected to a   
pretty bizarre accident (or perhaps vandalism - we don't know) at a   
school. We believe a fire burned in a rubbish bin directly underneath   
this Model A (number 400028). Below you can see the results; the   
soundboard got so hot that the varnish bubbled on the top side, yet   
the underside suffered no actual charring or burning (note in the   
second photo how the soot has been wiped away by my thumb in one   
spot). The last two photos reveal that enough soot was pouring up   
through the two holes in the underside (at the sustain pedal and the   
plate bolt) so as to leave a residue. 

It seems to me this would be a tricky thing to pull off even if one   
were deliberately trying to do it; specifically I mean getting the   
board heated just enough to bubble the varnish, but not so ho t it   
that things caught fire and burned. A pretty flukey event! I suppose   
there must have been just enough stuff in the bin to burn for just   
long enough (and hot enough) to cause only this amount of damage. 

The soundboard seems fine, still has plenty of power etc. We'll be   
replacing it, since the instrument is covered by insurance and it   
seems the prudent thing to do. But I wonder if anyone with more   
knowledge than I about internal wood structure will have an opinion   
on whether any lasting damage to the board will in fact have   
occurred, and if so how it might affect the tone or longevity? 

Sincerely,
