That's true. They do. A bit. But I've seen hammers never touched since leaving the factory that are cupped even worse than from pliers just from their natural expansion at the edges after being sliced into individual hammers. So you touch them up a bit by filing. Again, I said several times that the pliers treatment is for extremely hard hammers, not fine concert voicing. Extremely hard hammers are usually found on cheaper instruments. Usually. Not always. >This > outward bulge also results in felt being pulled away from the crown, > putting that under additional tension. I have found that needling, even shallow "sugar-coating", on the crowns of Yamaha hammers also makes the felt pull apart. As does filing. I think they just have really high tension compared to other hammers. --David Nereson, RPT
