This is a multi-part message in MIME format. ---------------------- multipart/alternative attachment *shrug* i run into it all the time, both the Kawai story (in regards to their stability) and the Steinway one (i'm in GA - woohoo what a climate! it's rare that at this time of the year i do anything other than dropping pitch). my question i would like to pose is this: does anyone have any arguments *against* dampp chasers? as a pianist, i grew up playing a little kawai upright that is now 25+ yrs old and still like new - upon its first regulation ever (after about 22 or so years), it really didn't need anything except an adjustment of the letoff. it holds its tune for years on end, both a testament to kawai, as well as to dampp chaser, as we have had a full system in the piano since it was purchased, and have religiously kept it watered. i ask about arguments against dampp chasers, because my current employer has actually been discouraging people here from using them, due to the climate. on one hand i can understand the point that if people get a full system installed, water the piano fairly well for the first few months and then start forgetting, it may cause more harm than good. however, i still don't really get it. he's also raised points that you don't really need the humidifier system here, but that the dehumidifier might overdo it.... uhm, it was my impression that the whole "climate CONTROL system" aspect included a thermostat that actually sensed when it needed to work? i'm not all THAT familiar with dampp chasers, except for my own positive experience as a pianist. are there any negatives of using this, or what? thanks, ilex -----Original Message----- From: pianotech-bounces@ptg.org [mailto:pianotech-bounces@ptg.org]On Behalf Of Marcel Carey Sent: Friday, September 17, 2004 12:05 AM To: Pianotech Subject: RE: Environmental tuning mysteries: solved, hopefully Dampp chaser with undercover. Marcel Carey -----Original Message----- From: pianotech-bounces@ptg.org [mailto:pianotech-bounces@ptg.org]On Behalf Of Piannaman@aol.com Sent: September 16, 2004 11:38 PM To: pianotech@ptg.org Subject: Environmental tuning mysteries: solved, hopefully Esteemed list scholars and such, I don't know how many of you remember the case of the corroding strings on a brand new Kawai Rx-3 I encountered in January of this year. I followed up by strongly suggesting that they stop mopping the radiant concrete floor with a vinegar-water solution(acid steam beath), which they did. I thouroughly cleaned the strings, tuned the piano a couple of times, and went back a week ago, and voila--no more corrosion! Not only that, the bloody thing was so close to being in tune I almost felt badly taking the money--well, not really... #2. I've been tuning a Steinway M that has new strings, hammers, pins, block, wips, but I'm not sure about the board. She's a very good customer, gets her piano tuned every 6 months like clockwork. I first tuned the piano 2 years ago, and today was my fourth trip out. First time, it was 10-15 cents flat. Second time, it was 10 cents or so sharp, third time, 10 cents flat; today 5-10 cents sharp. I do know how to stabilize a piano, so this was a mystery to me. At least until I heard the air conditioner go on. It's been hot in these parts lately, and pianos are going flat in droves(the houses in this part of CA are built for earthquakes, not inclement weather), but in the case of this piano, it's in a very large luxury home, with all the amenities. Unfortunately, the piano is directly under a duct that dumps cold, moist air directly on it. I'm convinced that is what's going on here. In the winter, the heat comes out of the same duct, but to slightly less effect, since the heat rises. The duct is now permanently closed. More details next time. Any comments or thoughts on this one? Just thought it was kind of interesting. Dave Stahl ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
