And now we move on to the spindle drive assembly. The spindle, as seen earlier, is splined, and has to
raise and lower as the quill is moved up and down. To drive the spindle, the belts mount to a pully that mounts
to this tapered piece, which is internally splined to match the spindle shaft. It has its own set of bearings,
but since it doesn't directly affect the rotary positioning of the spindle, they don't need to be as
high accuracy as those of the spindle itself.
