The whole IDEA is to bend the frigging wire so that when you spin the chuck
is traces out a circle in space that is perpendicular to the quill--you then
align the table to that circle.

Indeed, which is what I've said...

_IF_ that circle is rotating slightly off-axis, the length of the wire
to the point amplifies that and you align the table to it...

It relies for accuracy on the axis of rotation being colinear w/ the
quill precisely...
