<html><div style='background-color:'><DIV class=RTE> <P>Barbara,</P> <P>Jurgen at Pianoforte supply sells 2 thicknesses of keyend felt. The determing factor in replacking keyend felt has to do with the position of the toppost flange when the key is at rest and the intersection of the bottom of the underlever and the top of the felt when the key is depressed. If you run a thread from the balance rail pin to the underlever flange that line should bisect the toppost flange when the key is at rest and it should pass through the point where the key end felt and the key meet when the key is depressed. If your felt is too thick or too thin it will throw off these relationships. the thickness of the backrail cloth is also a consideration as it will affect the position of the toppost flange and your line. I hope I read your question correctly and that I didn't give you a bunch of information that you didn't need.</P> <P>Michael<BR><BR></P> <DIV></DIV><FONT color=#000000></DIV> <DIV></DIV></FONT></div><br clear=all><hr> <a href="http://g.msn.com/8HMAENUS/2752??PS=47575" target="_top">Rates near 39yr lows! $430K Loan for $1,399/mo - Paying Too Much?
