@nandric Sorry you have not been able to draw the attention of your select choice for contributors to your thread, I get the jist, that if the Maestro's are not commenting, other participation from non-reputed folk can hurt ones ambitions.
I sense your discontent with having been overlooked and take it on the chin fair and square, that as a non-reputed contributor, I have provoked a Big Ego and been dealt a blow as it it displays a retaliative bite.
To be informed that I have no understanding that a Tie Wire has a function to position the cantilever and coil in a precision positioning to align with a magnet, is a silly statement to make. The compression applied to the Damper Material and alignment of the coil, is to be achieved by a specific tensioning of the wire and compression of the Damper Material.
As I do not build or overhaul any type of Cart's, I am limited in knowledge in these areas, but have a reasonable 'laymans' handle on the parts seen belonging to a typical assembly and the fundamentals of the intended function.
As a 'Layman' offering a description as the one stated earlier in this thread, the Tie Wire is sharing a few roles of which one is to perform as a restraint. When the wire is set to a precision tensioning, the wire will be a constraint to parts that are able to move, and enforced to function within a operational envelope.
Setting aside your reciting of Olden Japanese designs and designers, and the construction of your inquiries and responses, I don't think our understanding of a MC Cart's operation is too far apart.
