Hi All! I am having a heck of a time trying to model this decorative spiral sweep, I would greatly appreciate it if one of you could offer some advice!

I am trying to approximate the ornament on top of these columns, not exactly, but enough so that the general idea is there.

Thanks for the response! I did try that earlier and unfortunately was not able to achieve the desired result. This is the same spiral rail scaled to the midpoint of the profile curve. What I need for this model is for there to be no empty space between each turn.
