I highly recommend getting a copy of Bill Spurlock's paper on <strong> Vertical Damper Replacement <a href="http://www.spurlocktools.com/id36.htm">http://www.spurlocktools.com/id36.htm</a> </strong>  <strong>.</strong>   Piano Forte Supply has 55 mm and 67 mm long upright bass dampers:  <a href="http://www.pianofortesupply.com/dampers1.html">http://www.pianofortesupply.com/dampers1.html</a></div> <div> </div> <div>Yes, you could measure the spring tension with a spring gauge, but any old upright is likely to have very weak wires. Consider replacement - and it is often easier to replace the entire damper lever assembly.</div> <div> </div> <div>I guarantee you, you don't want to mess with upright dampers without Bill Spurlock's paper in front of you.

Is the longer length going to cause a problem when the damper goes to lift? </div> <div> </div> <div>Also, while I am in there, is it a good idea to verrrry slightly (bend) each damper's spring wire so that it strengthens their pressure on the strings? Is there a way, perhaps a gage, to measure the pressure of these springs? If it can be measured, what should it be?</div> <div> </div> <div>Thanks</div> <div>Julia Gottshall,</div> <div>Reading, PA</div> </blockquote> </blockquote> </div> </blockquote> </body> </html>
