I've only installed one DC= in 30 years. I'm obviously missing a lot of income. I don't= see a big change in pitch on my customers pianos, so those two= you're working on must be my customers... David I. Original message From: David Love To: 'Pianotech' Received: Fri, 14 Jan 2005 06:58:27 -0800 Subject: RE: Dampp-Chasers and Piano Tuning/attn. SF techs Humidity is at it=92s lowest in SF at the moment. Very cold air,= heating on, no fog. If you come back in June it=92s likely that= the humidity will be over 70% and the pianos will have gone= sharp. That being said, some houses are able to maintain lower= indoor levels. Nevertheless, I always recommend a DC for most= SF customers.

SF techs I've got a Dampp-Chaser question for techs who work in San= Francisco a fair amount. Davids Love and Ilvedson come to mind= readily. San Fancisco is a notoriously foggy area, with year round= humidity and cool air. "The coldest winter I ever spent was a= summer in San Francisco," Mark Twain once said. I have several= clients there. I was there yesterday, around seven months after= the previous tunings for the two customers I visited, fully= ready to install heater bar/humidistat combinations in each of= the two small Korean grands. Much to my surprise, both pianos were right at pitch, and unisons= were fairly solid in both. Humidity in the houses was around= 50-55% in both cases. My question is this: once the piano has acclimatized to SF, will= the tuning remain stable without climate control? There is= certainly less variation in climate there than there is in the= South Bay, where it gets both colder in the winter and hotter= and drier in the summer. It seems to me, I need to continue to monitor regulation,= centers, and string condition. One of the pianos came from= Denver about 3 years ago, and since they arrived, the hammers= lifted about 3/4" off the rail. I'm curious about the experiences in these matters of techs who= spend alot of time in SF. Thanks!
