The tuning pins were loose enough to warrant a CA treatment and the customer is not discerning enough to nor has she the desire to move up. As she puts it(and I'm sure you've all heard it)she plays for her own amazement. <o:p></o:p> </div> <div> As I was sitting there the piano tipped on it's back on my tipper adding the CA, my eyes burning and watering, I sat back for a moment to breath some fresh air. I saw some vapor, it looked a little like cigarette smoke eminating from the TOP of the piano. This is one of the old Wurlitzers with the brown felt glued to the top and this vapor seemed to be coming from it. I watched it for another moment or 2 and it gradually stopped. I have probably done a dozen CA treatments to uprights, spinets, one old Wheelock grand, but I've never seen this before, anybody else? <o:p></o:p> </div> <div>  <o:p></o:p> </div> <div> By the way I'll take whatever heat you dish out for "saving" this fine specimen! <grin> -- Michael Magness Magness <st1:PersonName ProductID="Piano Service" w:st="on">Piano Service</st1:PersonName> 608-786-4404 <a href="http://www.IFixPianos.com">www.IFixPianos.com</a> email <a href="mailto:mike@ifixpianos.com">mike@ifixpianos.com</a> <o:p></o:p> </div> </div> </body> </html>
