Mounting a turn coordinator on the tail?

The horizontal component of lift behaves like a string tied to a rock

No, it doesn't. The lift vector points in a direction (roughly)
perpendicular to the wing. Nothing causes it to point to the
a "center" other than the other aerodynamic surfaces .

The lift vector(s) point perpendicular to the wing (s). With a dihedral
angle in the two wings there will be horizontal components of the lift
vectors and in level flight they will be equal and opposite, canceling.
In a turn with the plane banked, it's easy to see how one lift vector
will point entirely straight up while the other doubles its horizontal
component. This pulls the plane toward the center of the turn. (It
sure is easier to explain with a blackboard!)
