That's MDF as in Medium Density Fiberboard, not cast iron. Which is why the treble tuning pins were spread out of half of God's creation. The panel would not take much of a point stress. Wonderful idea, but not tested well enough or long enough. And designed entirely by engineers -- with an engineers faith in numbers -- without a piano designer or piano tuner in sight. Tuning those treble strings was an interesting experience in patience. Regards, Del
