Your Steinway is getting killed more quickly than it needs to be, and your people should be told that they are risking a very valuable asset. At best pitch instability, at worst the junking of the piano after the rim delaminates from dry winters.</DIV> <BLOCKQUOTE style="PADDING-LEFT: 5px; MARGIN-LEFT: 5px; BORDER-LEFT: blue 2px solid"> <DIV><FONT size=4>The camp also wants dampchasers in a few other uprights in the practice rooms in the back of the audtorium.

I <BR>just tuning a Steinway grand and upright at a YMCA camp that operates only <BR>two months a year, July and August. The camp is on Lake Champlain in New <BR>York State, and the camp Director, a music teacher, says the summers are <BR>very humid. Teh grand alreaddy has a "heating bar". Do the painos, given the <BR>climate, warrent a complete Damp-Chaser system? <BR><BR>Wayne Williams <BR>Schroon Lake, NY <BR>----- Original Message ----- <BR>From: "R Barber" <bassooner42@yahoo.com> <BR>To: <pianotech@ptg.org> <BR>Sent: Monday, July 16, 2007 2:36 PM <BR>Subject: Coastal Dampp-chaser calibration <BR><BR><BR>>  The owner has double-paned windows, weather-stripped doors, drapes- <BR>> generally equipped to protect his niche from the environment, but prefers <BR>> open windows.  There is no central humidity control.  There is usually a <BR>> 24-hour on-shore breeze, so the typical climate will be high RH, about 95% <BR>> of the year.  RH ranges between 55-100% daily, but occasionally there is a <BR>> breeze from the off-shore direction when RH drops to 20% or below, <BR>> sometimes for a few days at a time. <BR>>  I've heard two votes for the wet, and I'm tending in that direction. <BR>> Thanks for you input! <BR>> Richard Barber <BR>> <BR>>> My recommendation would be to know the typical range of relative humidity <BR>>> (RH) the house (?) experiences. If the house is a old wood frame, windows <BR>>> are often open, no central air or heat, then sure, pick the <BR>>> "wet"-calibrated Dampp-Chaser humidistat to match the outdoor <BR>>> environment. But many modern homes are well insulated from their outdoor <BR>>> environment and RH ranges in them may have little to do with outdoor RH <BR>>> ranges. Not only are modern homes well insulated from the outdoors (heat <BR>>> AND humidity), but any home also has it's own humidity sources - cooking, <BR>>> showers, etc. <BR>>> <BR>>> IMHO, if you are going to err at all, and being that you plan to install <BR>>> a full system (are you sure its gets dry in the home?), I would go with <BR>>> the "normal" humidistat. Another consideration might be if the instrument <BR>>> is old with a sagging soundboard and less-than-tight tuning pins, you <BR>>> might want the "wet"-calibrated Dampp-Chaser humidistat to help the piano <BR>>> out a bit. <BR>>> <BR>>> Also, have you checked to see whether the home has a central humidity <BR>>> control system? <BR>>> <BR>>> Many things to consider. At least the piano is getting a DC system - <BR>>> always a good thing! <BR>>> <BR>>> Terry Farrell <BR>>> <BR>>> ----- Original Message ----- <BR>>>> Do you think a "wet"-calibrated Dampp-Chaser would be a wiser choice <BR>>>> than the standard calibration for a client on a foggy coast? <BR>>>> Installation to include string cover + undercover, complete Dampp-Chaser <BR>>>> (not just rods), to cover off-shore dry spells. <BR>>>> <BR>>>> Thanks, <BR>>>> Richard Barber <BR>>>> Santa Clara Valley, CA <BR>>> <BR>>> <BR>>>     * Previous message: Coastal Dampp-chaser calibration <BR>>>     * Next message: Coastal Dampp-chaser calibration <BR>>>     * Messages sorted by: [ date ] [ thread ] [ subject ] [ author ] <BR>>> <BR>>> More information about the Pianotech mailing list <BR>> <BR>> <BR>> -- <BR>> No virus found in this incoming message. <BR>> Checked by AVG Free Edition.
