<div>Alan</div> <div> </div> <div>The "mold" is verdigris, also referred to as green gunk. It is easier and cheaper to ream and repin, and it will solve the problem for a while. But it isn't a permanent solution. <br> <br> The problem is the bushing cloth, which was impregnated with paraffin wax. The wax reacts to the nickel on the centerpin and produces the green gunk.  So although you can remove the centerpin, and ream out the green gunk, the wool still has the wax. So the problem will come back, eventually. But since it takes about 25 - 40 years for the chemical reaction to have any kind of effect, you, and your customer, won't be around to worry about it. Besides, by then the piano will probably have other problems. <br> <br> </div> <div style="CLEAR: both">Willem (Wim) Blees, RPT<br> Piano Tuner/Technician<br> Honolulu, HI<br> Author of <br> The Business of Piano Tuning<br> available from Potter Press<br> www.pianotuning.com</div> <br> <br> -----Original Message-----<br> From: Alan Barnard <pianotuner@embarqmail.com><br> To: pianotech@ptg.org<br> Sent: Sat, 5 Jan 2008 12:15 pm<br> Subject: Rebush (or elect someone else?)<br> <br> <div id=AOLMsgPart_2_c04d83a5-e37d-4a52-ad36-4b425b729033> <STYLE>#AOLMsgPart_2_c04d83a5-e37d-4a52-ad36-4b425b729033  </STYLE> Got a 1916 Steinway upright that's definitely an oldie but moldy -- all flanges practically seized up with mold in the bushings. Rather than rebushing everything or replacing the flanges (super expensive!), has anyone had success just reaming and repinning?<br> <br> BTW previous tech(s) had put large lead weights near the back of all the keysticks (2-ouncers, I'd guess) AND screwed jiffy leads to most of the stickers!
