At a school earlier this month the head of music asked if I could fix the sagging keybed of one of their 1970s Marshall & Rose uprights (quite nice school pianos of that era). The bass end was hanging down at least half an inch. I managed to fix it, by propping the middle of the keybed on a chair such that the front of the piano was lifted off the ground and the keybed forced back up to where it should be, letting me glue and screw it into place. At another school last week the same thing was beginning to happen to a similar piano. This time both ends, but only about a quarter inch. Similar repair, this time using an old car jack. Three inch screws in through the ends of the key cheeks which are pretty solid. (The key cheek blocks were removed and the glue worked in before lifting the keybed up). Not elegant, though the pianos are pretty beat-up anyway. But next time I attend, if I am satisfied that everything has remained solid, I will cover the screw heads with a suitable filler.
