---------------------- multipart/alternative attachment Julia, Now that I am picturing it correctly--hard to do late at night...:-)--I think Isaac is undoubtedly right. I've had similar occurences in pianos that are poorly regulated where the jack can't get back under the butt, so that's worth checking, too. My money says it's the pinning, though. Now's a good time to get a set of reamers if you don't already have one. Sounds like you're going to need it.
