<WBR>Rust isn't just where you can see it. It attacks all metal parts, over, under, around and through. <br> In addition to new strings, and getting the bottom of the plate sandblasted, you might also want to check the key pins, center pins, damper wires, key leads, trap bolts, etc. etc.  Sounds like someone owes the church a new piano.<br> <div style="CLEAR: both"><br> 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: Ron Koval <drwoodwind@hotmail.com><br> To: caut@ptg.org; pianotech@ptg.org<br> Sent: Fri, 2 Nov 2007 5:48 pm<br> Subject: Unfortunate D/C problem<br> <br> <div id=AOLMsgPart_0_528546b0-5b5b-47bd-8b47-2b4e93a852ac style="FONT-SIZE: 12px; MARGIN: 0px; COLOR: #000; FONT-FAMILY: Tahoma, Verdana, Arial, Sans-Serif; BACKGROUND-COLOR: #fff"><PRE style="FONT-SIZE: 9pt"><TT> Newer church piano - Dampp Chaser I was just there 5 months ago... As I was tuning for a recording session, could it be? Rusting strings? Pull out the flashlight, get up and walk around - yup, even a bunch of "rust dust" settled on the soundboard. It seems that the person in charge of filling the unit thought that ANY de-scaler would be fine to use. Used the gallon jug of stuff for the dishwasher and proceeded to add that with every fill up. -gulp- What a mess. I removed the D/C unit - hanger brackets just about rusted through. Smart bars dissolved... So, will the rust continue to attack? It had hydrochloric acid in it. Strings, nose bolts, probably the bottom of the plate... How much of the piano needs to be replaced? Yikes! Ron Koval Chicagoland _________________________________________________________________ Help yourself to FREE treats served up daily at the Messenger Café.
