Guangzhou is roughly the latitude of Havana, Cuba. -----Original Message----- From: pianotech-bounces@ptg.org [mailto:pianotech-bounces@ptg.org] On Behalf Of John Formsma Sent: Monday, January 30, 2006 7:51 PM To: 'Pianotech List' Subject: RE: Whether the weather? I don't know, Ed. Just looked on the net -- Guangzhou's average annual humidity is 77%. Right now, New Orleans is 30% and Guangzhou is 57%. If pinblocks were drilled at 75% R.H., then were shipped to an area that had swings from 25%-70%, it could easily explain why the early Pearl River pinblocks disintegrated in a few years. I'm no wood expert, but I'd say things would have been better had the factory been climate-controlled then as it is now. I also have a few grey market pianos that are doing well. Yamahas and Kawais. One Yamaha, though, has tuning pins that are somewhat looser than its comrades designed for the U.S. That's the only one on which I've noticed anything different.

He said Guangzhou is pretty humid -- roughly like the tropics in S. America. Maybe they don't have the huge climate changes that many places in the U.S. experience. ??? >> I understand that, however, I don't think anyplace can get much more humid that New Orleans, so I still have to wonder what is going on. I dunno, I have wondered how much of the Yamaha "grey market cautions" are based on marketing and how much is really based on the wood. I have several customers with Kawai "Model 500" pianos from wayyyy back, and they haven't fallen apart or anything else that I can ascribe to mis-climate. (I have also seen some obvious grey market pianos that seem to behave just like their more legitimate brethren). I do wonder...
