You would also want pretty stiff tuning pins, not the >kind utilized in Boston uprights. Sure on the last point. But hypothetical pianos don't suffer the same practical constraints as normal pianos. ;-) It wouldn't be difficult to have identical total string lengths for each trichord. So do you (others) agree that it would be advantageous as proposed: "friction free" bearings, solid stable front and back lengths, and same total string lengths within a trichord?
