Looking to model a compact fluorescent bulb but not sure how to do the spiral portion. Any guidance on how to make the spiral like in the attached image?

Right off hand, I would say spline and rail extrude. But thats just me. I don't know if there is an easier way or not.

Lathe with an offset will do the job, note there are 2 coils there both going the same direction.

You would have to manutally model the top and bottom parts though.
