Good answers all! ...and I'll keep my eye out for some of those things mentioned which I've not yet had the privilege to encounter. ...and the winner, coming closest to the correct answer, is: >>Hmm, I had a squeak in a D once, it was from the lyre's microscopic movement >>against the bottom of the piano. ???? >>Ed It becomes a reinforcement of my policy to always (or at least try to) put every screw back into the exact hole from whence it came. In the process of refinishing (not by me, BTW) the screws for the lyre mounting plates got moved around. Not ordinarily any big deal, except that in this case one of the lower plate screws was driven in slightly angled. (original from factory, and one of the other screwheads shows filing) The result was that part of that screwhead was sticking up far enough to touch the upper plate. I ran my 6"/150mm steel rule across as a straightedge to check and it snagged on that screw head. That screw was enough to "high-center" the lyre. Compounding the problem is the fact that the wood on the right (damper pedal) side of the lyre top displayed a little barrel warp making the top surface slightly convex. I suspect that when I remove the plate I'll find a buildup of finish which also brought the plates closer together. The plate top is closer to the wood surface than I like to leave them. The squeak was either that screw or the plates when the convex top and protruding screw conspired to rock the boat. I temporarily inserted business card shims, and all was quiet... Eventually I'll true up the top surface of the lyre and remount one of the plates. Lowering the plate would help to firm up the connection, but I fear that the warp would still allow movement, so I'll do both.
