If this is truly a problem and you must solve it I would get some help and remove the lid and hinges and turn the piano up side down and get an air router and rout off a 1/16" or 3/32" for screw clearance. Doing a good and safe setup is going to take more time than the doing of it. DOn't forget eye and ear protectors. Don't worry about the bass hammers, this is a common problem with poorly thought out designs. Those bridge agraffes get loose and cause falseness and odd tones. They can be fixed rather nicely by drilling a small hole through the base that goes into the wood hole and dribbling CA glue into the hole until the bottom of the hole fills up to the top of the bridge. Once this stuff sets those agraffes will go nowhere. Pity the poor schnook that has to remove them fifty years up the time line. Newton
