I have replaced damper felts and never worried about the tension in the damper springs. The ringing subsided in the old uprights that I have done, however, the ringing could have been less. I am doing a damper job right now for a lady and this time, I "massaged" the damper springs alittle to renew the tension, </DIV> <DIV>        Friday I am going to her place to put the action in and glue the dampers on the newly sanded blocks. I will see then the fruits (or not) of just bending those springs <EM>very </EM>sliiightly. I did it when I had the levers off and out while cleaning/sanding off the old felt in my shop.</DIV> <DIV>         Actually, I asked the list here, that same question, about messaging the old springs, and I guess no one caught the question, because I got no response, so I figured I would just go ahead and re-tension them slightly, Here's why:  I was told at tuning school that you can slightly bend the spring rail (hammer) springs to re-juvinate the tension in uprights and also I was told you can do it to the repittiion springs in a grand. They basically work the by same principle as damper springs so I figured why not with the damper springs. We shall see, Friday.</DIV> <DIV> </DIV> <DIV>       So, I really cant give a definite answer on re-tentioning. I am guessing. I also know there is a way to measure the tension, but I dont know what gage to use or how to use it. This is on my list of things to check out.</DIV> <DIV> </DIV> <DIV>Julia Gottshall</DIV> <DIV>Reading, PA </DIV> <DIV> </DIV> <DIV>In a message dated 7/25/2006 11:35:11 AM Eastern Standard Time, chief_retired@pacinfo.com writes:</DIV> <BLOCKQUOTE style="PADDING-LEFT: 5px; MARGIN-LEFT: 5px; BORDER-LEFT: blue 2px solid"> <DIV><FONT face=Arial size=2>Hi Julia,</FONT></DIV> <DIV><FONT face=Arial size=2></FONT> </DIV> <DIV><FONT face=Arial size=2>Thanks for the comments. </FONT></DIV> <DIV><FONT face=Arial size=2></FONT> </DIV> <DIV><FONT face=Arial size=2>The pedal is ok.
