Richard, I've been following your idea with interest. Noticing that the capstan and wippen heel stay in contact throughout the keystroke, my immediate reaction was, "Is this some kind of perpetual motion machine?" But as I think about it, it may be something more akin to power steering. It would be so if, in fact, the magnets effectively move the capstan closer to the balance pin, changing the key ratio. What I wonder is whether magnet assist maintains its effectiveness as the speed of the keystroke changes. Specifically, if the magnetic field is more compressable than the wippen heel cloth, that the mechanical coupling will become more dominant on heavier blows and the magnetic assist will decrease. I don't know how this could be measured but I guess it would be easy enough to try it out. What I find most interesting is that the DW is reduced without affecting the UW nearly as much. I think this is what separates it from magnetically "weighted" keys and "miracle wips". Bravo. Tom Cole
