The plate bolts ,especially the lower ones (at the trap board) must be tight. If these are tight then the maker MIGHT have used a warped plate and forced it in by screwing it down without shimming to accomodate the warp. I wild guess but to find out, loosen the bolts and see how far the plate pulls away. Don't forget to let the tension down before trying this. I would like to ask, if you move the piano back, does it go back into tune? I once knew a piano that was set up on a milk crate to do caster work. It went out of tune but it was back in tune when lowered. (Well almost, but not nearly as out of tune when it was moved up) ---ric ----- Original Message ----- From: <kam544@flash.net> To: <caut@ptg.org> Sent: Monday, April 09, 2001 3:33 PM Subject: need ideas | Dear List, | | I recently have discovered a problem with unlevel floors in some university | classrooms causing the pianos to go out of tune when moved only a few | inches from the tuning location. | | Other than requesting the pianos not be moved, are there any other | corrective measures or ideas that someone has employed with any success? | | Thank you, | | Keith McGavern, RPT | Oklahoma Baptist University | Saint Gregory's University | Shawnee, Oklahoma, USA | |
