It closed up the separation completely.  I checked the pressure bar screws to see if they were stripped and was able to get about 1/2 turn on ones in the suspect area and the pitch came up 20-30 cents in that area. But they were not stripped.</div> <div> </div> <div>Ah haa, problem solved I thought.</div> <div> </div> <div>I lowered the pitch in octave 5 back down and tuned the whole piano.  The next day the customer called and said those notes were very out of tune again.</div> <div> </div> <div>No obvious separation of bridges and no cracks in soundboard.  Any ideas on what I may be missing???</div> <div> </div> <div>Randy Mangus, RPT</div> </FONT></div> </div> </font>
