     Borrowing heavily from a mechanical drafting course taken many moons ago, one can make a spiral by using a series of arc segments, each sharing one of four centers and radii adjusted such that the end of one seg meets the start of the next.

     google "drawing archimedean spiral" for hints on how to apply a series of axlPathArcCenter's  to achieve your goal.
