Hi Dale,
Nope.. you got it right. I got so many things going on right now I just
wrote 5 % without double checking. Sorry bout that :)  He didnt say how
long they've been doing things this way. In anycase.. this should be as
straight a skinny as we can expect to get. So ... in the interests of
providing a common basis for the whole subject matter...why dont we use
this figure in our calculations.

Would be interesting in light of David Porritts posting to find out if
there was a change from 4.5 % to 5.5 % right after that episode.

Hi Richard.  Sorry about the difficulty you are having there, but I do
appreciate your support of Steinway.  The
ribs are flat  and pressed into a curved caul.  However, the panel is
dried to 5.5%.  Hope that clears it up.
Best regards, John


Cheers
