Rib Crowned Hamburgs ?

  Well whatever the truth of the matter is &  perhaps we  don't know all of 
it.
   I rarely see Hamburg Steinways but the several newer ones I've  seen were 
knock outs tonally. The Os' I've seen   are wonderful  sounding  pianos. I 
heard something truly different than the NY  version.
   Keep in mind that some crown in the rib is better than none  & a spruce 
rib in my opinion, in the Hamburg Stwy  a  better choice in wooden engineering 
materials than the softer sugar pine  ribs of purely CC boards. The tone tells 
a huge story. Maybe not a perfect  design but headed in a better direction 
than some.
  Thanks for the information

As Ron reminded, and has others have stated many  times before Rib 
crowning are not mutually exclusive, and in this case  obviously both are 
present. To what degree is another matter. They just  dont use the method 
of drying the panel to very low EMC's to get there,  opting instead for 
pressing in a caul with a greater curve then that found  on the ribs.

In any case my opinion of their tone quality of  course remains 
unchanged, and I fail to see why it should be  affected.  I simply 
reported to the list my observations for  everyones own edifications.  I 
do this all the time, and most often  it seems manufacturers are drying 
out to very low EMC's to gain whatever  compression levels they want. 
Seemed only fair to, in the same spirit of  curiousity and non-biased 
interest, report this experience as  well.

On a side, they confirmed what John Patton said to me a couple  years 
back, that in New York they dry to 5 - 5.5 % EMC before ribbing.  
Otherwise they follow similar  methods.

Cheers
