</DIV> <DIV> </DIV> <DIV>On the grand, from examination, I worry a bit about warped keys, but won't know that for sure until I take the action stack off and am able to handle each key.</DIV> <DIV> </DIV> <DIV>It seems I have two courses of action:</DIV> <OL> <LI>Do nothing at the moment, let humidity levels go down, and see how the pianos are affected; also, strongly encourage heater bars installed on each, preferably immediately, to stabilize the humidity in the piano itself. <LI>For immediate action, at the very least, on the spinet apply silicone/teflon powder to the key bushings, and (very minimally) ease the key bushings; on the grand rebush the balance rail pins, polish the balance rail pins and front rail pins, apply silicone/teflon powder to the bushings.  The grand also calls for adjusting some of the back checks, that are 'grabbing' the hammer tails.  Also, strongly encourage heater bars for long-term stability. </LI></OL> <DIV>Oh, great list, I solicit your thoughts on this situation.  BTW, the lady several times made the point of saying that they were on social security, and couldn't afford to pay much (that's not going to cause me to underbid or lower my price--they did buy these two pianos, after all!).  After about the third time mentioning SS, I gently pointed out that I am helping to pay her social security!!  Too, from my limited exposure to sales, I remember that most people are able to afford what they want to afford. </DIV> <DIV> </DIV> <DIV>Thanks for your insights and suggestions.</DIV><SPAN class=sg> <DIV>Richard Morgan</DIV> <DIV> </DIV></SPAN></DIV></DIV><BR> <HR SIZE=1> Be a better Heartthrob. <A href="http://us.rd.yahoo.com/evt=48255/*http://answers.yahoo.com/dir/_ylc=X3oDMTI5MGx2aThyBF9TAzIxMTU1MDAzNTIEX3MDMzk2NTQ1MTAzBHNlYwNCQUJwaWxsYXJfTklfMzYwBHNsawNQcm9kdWN0X3F1ZXN0aW9uX3BhZ2U-?link=list&sid=396545433">Get better relationship answers </A>from someone who knows.<BR>Yahoo!
