I an requesting help on a personal project of mine where I am creating a transmission-line spiral-shape enclosure for some speaker drivers. This my first attempt at generating a body and my plan was to shell the body once it was created, however, I am stuck on this loft, so if anyone has any insight into approaching this problem I would appreciate the help!

It looks like your circle, at its top, is tangent to the spiral. I would make the plane of the circle sketch angled so that the top of your circle touches the spiral 90 degrees down (along the spiral) from where it touches now. You may also need to break up the spiral sketch into several line segments so that the top and bottom of the circle are constrained by two guide curve selections. I hope this helps, I'm learning too!
