Wave Spring

Hi, I am trying to create a Crest-to-Crest Wave Spring (see pic below). I can only create one wave at a time with a closed Law Curve and then creating a rotated instance of the geometry (just a close repesentation). Would like to have a continuous Law Curve with X amount of turns. Can anyone help.

I would also be interested in this. I have another post for a similar thing, but with one bend across the entire surface.
