Regards Michael G.(UK) ----- Original Message -----=20 From: Cy Shuster=20 To: Pianotech=20 Sent: Saturday, May 28, 2005 2:36 AM Subject: Discoloration on underside of pinblock New customer today with a gorgeous Yamaha C7, 1993. It was in = Tennessee for a while, and has been out here for several years. I felt the edge of the pinblock through the half-opened fallboard, and = felt ripples in places. Removing the fallboard, the underside was = stained dark in large areas across about a third of it, like a walnut = stain (wish I had a picture). In some places, there were thin white = lines in the shape of the grain, with broad dark lines between them = (where the harder wood didn't absorb the color?). =20 The color didn't scrape off with a fingernail. In the dark areas, I = could feel ripples, parallel to the bass strings (from the milling = machine, perhaps?). The light areas were very smooth. No other stained = areas in the action cavity. Pin torque was tight. No signs of moisture damage, save that if you = caught a reflection off the soundboard just right, you could see a few = cracks starting to form in the varnish, along the glue joints. Any ideas as to the cause? --Cy Shuster-- Bluefield, WV ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
