Just some ideas here, different approaches. Maybe one will work better than your loft with box.

Try to get same number of verticies in inner and outer curve of the winder. Sometimes this makes a loft go better. If your box is a rectangle, try converting it to poly, or the other way around. Sometimes these things make a difference.

Instead of Loft, isolate your upper Nurbs and try Model/3d Power Pack/Convert Nurbs to Surface. This might make a better surface than the loft, but it will be only a surface. If you need the volume, you could duplicate the surface and it move down an inch then loft or create surface the edges and add all to create the approximate volume.

This could also work for lofts of upper and lower surface. Instead of using the box, what if you loft, say the upper surface since those nurbs seem to take the loft well. Then duplicate in place and move it up 1" and loft the edges. After you join the top, bottom and edges, you will have approximately the one inch volume. Probably about as close as a plasterer will get.

Good luck!
