Lathes, Spins, and Screws

If this is the wrong place to post this question, please redirect me and I will repost in new location. Using Blender, for lack of a better description, I’m trying to turn a curve into a hose (solid, rather than hollow would be preferred). If I extrude, spin, or screw, I get the wrong result. I just can’t seem to find a tutorial that explains (step, by bloody step!) how to do it. Any clues would be welcome!

Try this:

Find “The basics of BevOb extrusions”
