This is a multi-part message in MIME format. ---------------------- multipart/alternative attachment At the California Conference, I attended a grand piano maintenance class sponsored and run by Steinway techs. I was surprised when they made a specific point of telling us that a piano under tension does not have to exhibit any crown, yet still sound and work just fine.=20 =20 This wasn't in response to any questions, it was a topic on their = agenda! =20 They also said that it might explain why some pianos are so reactive to seasonal changes while others, e.g. Acrosonic, tend to be more stable. =20 Hmmmm .... =20 Alan R. Barnard Salem, MO -----Original Message----- From: pianotech-bounces@ptg.org [mailto:pianotech-bounces@ptg.org] On = Behalf Of Terry Sent: Thursday, March 24, 2005 8:01 AM To: Pianotech Subject: Re: Steinway with reverse crown I changed the name of the subject line because a Steinway with reverse crown has nothing to do with a subject line =93New Baldwin=94 Please = follow questions interspersed below. ---ric=20 =20 =20 I had a new Steinway with the exact same circumstances (full = quarter-inch reverse crown). Stenway wouldn't do anything because their opinion was = that there was nothing wrong with the piano. =20 Terry Farrell =20 How did you determine this? =20 =20 What? The reverse crown, or the Steinway opinion? Okay, okay, I simply stretched a string tight across the back of the soundboard until it = touched in the center (or there abouts) of the panel and observed that the ends = were a good (or bad) quarter-inch off the panel.=20 =20 The condition you describe, it seems would tend to pull the strings up = off the bridge pins or be pulling the pins out of the bridge. =20 No, it wouldn't do that at all. In my original post I stated that there = was plenty of downbearing. It would appear that the board was = reversed-crowned prior to bridge installation. =20 =20 Was this across the whole bridge?=20 =20 Don't remember - it was before I got into piano technology. I doubt I measured between all ribs. But a reverse crown between any ribs clearly suggests a real mess. =20 What model?=20 =20 As stated in original post, 1098 - 46" studio. =20 How new?=20 =20 As stated in original post, new, new, new, only weeks old (at least from original purchase) when measurements made. =20 Was it sold? =20 =20 As stated in original post, I bought it - waddaya mean? =20 How was the bass bearing. =20 =20 Don't know for sure - my recollection is not clear on that - but I = remember downbearing in general was okay. =20 Do you mean =BC reverse bearing? =20 =20 As stated in original post, downbearing was fine - normal. What would = 1/4 reverse bearing be? =20 Did SnS have a tech of their own evaluate the piano after you? =20 =20 Yes. Even John Patton - I think he was the head of S&S concert techs (or something like that). =20 Do you mean if you loosened the string and took it off the bridge pins = then pulled it back up, the bridge would be =BC inch below the level of the = string? =20 NO! The downbearing was fine. It would appear that the board was reversed-crowned prior to bridge installation (most likely explanation). = =20 =20 If so I would like to come and take pictures.=20 ---ric =20 =20 Well, you probably could - a couple months ago I saw the same old piano still for sale at the local Steinway dealer - I think they were asking = $18K for it! You'd have to talk to them about the photo shoot though. Somehow = I suspect they might not be too interested in it. =20 Oh, BTW, I have at least a dozen 8 x 10 color glossy photos with circles = and arrows and a paragraph on the back of each one that fairly clearly = detail the troubled saga of this piano. =20 Terry Farrell =20 -- No virus found in this incoming message.
