It’s been known for some time now that pressing wool felt with lots of moisture and too much pressure and too much heat produces piano hammer shaped objects that are incapable of producing the basic musical nuances we expect from our pianos yet some hammermakers—and pianomakers—continue pressing wool felt with too much moisture and too much pressure and too much heat forcing the stuff into something having the shape—but not the soul—of piano hammers. And piano technicians continue buying these atrocities and they continue recommending the pianos fitted with them to their overly trusting customers. And then, when the pianos don’t sound “right,” they have to drag out every heroic voicing technique in the book in a desperate attempt to make those piano hammer shaped whatever-they-are musically less bad.

It does absorb and desorb moisture and the tone characteristic changes as a result. Normally the change is slight and gradual. This may not be so slight. I'd certainly let time do what it will before attempting to chemically harden hammers that already have the reputation of being granite in disguise. And then, if they do not harden up enough to cause permanent hearing damage after they have dried out I'd sand off a layer before pouring on the chemicals. And, as Ron suggested, I'd try ironing them a bit. ddf Delwin D Fandrich Piano Design & Fabrication 6939 Foothill Court SW, Olympia, Washington 98512 USA Phone  360.515.0119 — Cell  360.388.6525 <a href="javascript:return">del@fandrichpiano.com</a> — <a href="javascript:return">ddfandrich@gmail.com</a> -----Original Message----- From: <a href="javascript:return">pianotech-bounces@ptg.org</a> [mailto:<a href="javascript:return">pianotech-bounces@ptg.org</a>] On Behalf Of <a href="javascript:return">tnrwim@aol.com</a> Sent: Thursday, November 29, 2012 8:30 PM To: Pianotech Subject: Re: [pianotech] Brighter Yamaha Thanks for the advice, so far. As a follow, I've that high humidity has an effect on hammers. This piano sat in empty house for five years in Hilo, but was moved to Oahu 2 weeks ago and is now in an air condition hall. Hilo is on the Windward side of the Big Island of Hawaii, where it rains A LOT. The piano is only 6 years old and has never been used. It has had a string cover and a damp chaser, so there no damage, and the hammers are virtually brand new. Would the being exposed to a lot of humidity be the reason the hammers are soft, and if I just wait 6 months they will brighten up by themselves?
