Good point Don. I had this also happen to me = recently, when I leveled keys on a 20-year old grand: not old enough to need new = felt (or so I thought on the first round of key leveling), but if those punchings = don't go back in exactly as they were (which they never will), you will be in = trouble. I solved the problem just as you suggest - new thin felt punchings. I = have not been ironing them, but now that you mention it, I suspect it would be a = wise thing to do!
