Change the pad to a Silvers pad (real, not a repro, if you go repro, use Griffin & Howe pad), have a g'smith/woodsmith like Dennis Earl Smith, Gunter Pfrommer, or in your neck of the woods, give Dave Wolf in Waco a call, have em' mount it and tell them you want it "polished","contoured" and the edges rounded, after you get it back rub it down with vaseline. I believe the way the pro's get em smooth as a babys behind is to freeze the pad and polish with fine sandpaper until the desired texture is achieved.
