It should be something like this.

Here attached the best i can. Tangency and normal costraints everywhere.

Interested in how to get curvature continuity everywhere.

Oh, now that's a dangerous challenge

    Problem is there has to be tangent surface connecting those 2 rings without that little collapse.

        It appears that the center is not flat. Like it somehow has to merge with an oval(ish) X and Y section.

        Why surface it, it appears you can achieve this with solids.

        Edit: I just did it with a solid and a rnd containing 3 sets of full rounds. 2 features. I'm assuming it's toroidial on the ends?

        This is really a challenge without the advanced surface extension.

        Indeed, 2 features will make the basic part. This one has a center "bulged".

        Warp can do this too but not as controlled.

          Your method is sweet too,didn't thought of this way when i started,all i was doing was going through the imported feature.
