8 - 10 paper punchings under the front rail felts shouldn't be a problem. That amount, and up to 12, corresponds to NY Steinway specs, at least on the recent D I worked on. Funny, those Youro Peon piano companies - you know: Grotrian, Schimmel and so on - seem to think you shouldn't put more than 4 paper/cardstock punchings under the front rail felts. I think they are just being cheap. A real luxury piano has LOTS of paper and cardboard it it. Too bad the dip is already so shallow on the Hamilton, otherwise a person could add more paper!!
