Bummer Don As a last resort. See if you can create a space between the post and the soundboard so there is no impingement. Who knows it may sound quite good. Perhaps you are unaware that some makers Have & are producing reverse crown boards and they sound quite good. At this point you and the client have nothing to loose. Good Luck Dale S.

The piano was evidently in avery damp environment at one time, since there were several loose glue joints,including the bass bridge to apron and some plywood delaminating in the bottomboard . The inversion is severe enough that the ribs near the center of theboard are pushing against a back post. The tone is even but weak. Is there anyway to flip the soundboard back to its original position without destroying it?Can I just remove some wood from the back post to give the rib clearance andexpect that to enlarge the tone? Bearing can be adjusted because of theAccu-hitch pins. Thanks for any suggestions or prior experiences. Don Hubbs -------------- next part -------------- An HTML attachment was scrubbed...
