   >>>>>>>>>>>>          Thank you so much now we're getting somewhere. Are 
you able to describe how much time this took and what effects this had on the 
wood at the rim joint. How was the steam directed? Another  difficulty I 
thought of after my first post was that removing the acoustic dowells makes 
that part of the board weaker as well and removal more problematic as the 
board has a better oppurtunity ti disintigrate.

>>>>>>Was there a physical demonstration or slide show demonstrating the
   actual doing of it? Also  I'm curious as to the rational of such a 
procedure from a tonal point of view and also economic. Tonally was it their 
opinion that the results were as good or better than installing a new board. 
That seems to be the inferance whenever this comes up. 
     My thoughts about economic feasibility tells me this sounds like a more 
time consumning procedure than a new board. Assumning  this to be  true how 
do you sell this whole idea to a client. I don't believe you can imperically 
state that the results are going to be better than a really first rate new 
board installation.  This idea to my mind would have to be that the job be 
promoted/ sold on the notion that the old wood is better louder, sweeter, 
touchy feeleier or some such. I'm not being synical(well a little) but these 
are the realities of  everday business that can not be ignored.
  Personally I would not want to go through the time consumning learning 
curve only to end up saying you know I was right the new board sounds better 
afterall. Or feeling that any part of the job was compromised even a little 
by perhaps too much damage that was unintentionally done removing the old 
board with steam. I mean these are water soluble / old hide glue joints after 
all and the edge glued panel butt joints can not help but be affected to some 
degree raising more question marks about the integrity of the outcome in my 
mind.
    So may be this could be sold as a second rate repair with a disclaimer.
    Never the less I would be willing to try this once to see what gives ,if 
I can get the board out in a fairly intact way. But not on a customers piano 
the first time.

            Patrick thanks>>>>>>>>>Dale Erwi>
