OK, I found the problem but one still remains.
For the bevel issue, I had the fist point of the spline on the very inside, where the lathe rotates on it’s center point. I set the first point to one of the points on the outside of the spline and that fixed the reverse bevel.
Only problem now is that at the very middle of the lathe, the bevel stops and starts again at the center point. You may have to try this for yourself to see what I mean but basically, the bevel does not continue through the center point of the lathe, the bevel lathes too. Bummer. Really didn’t want to have to convert to a mesh.
