Bulbous ring question

 From:  gunter511

Hi All,

I had help from the forum creating this bulbous ring in the past, thank you to all who contributed.

I'm now trying to set a gemstone with a chamfered bezel set into the ring.

Could someone please explain how I would go about getting the circled areas of the ring to
meet the flat edges of the bezel?

Thanks in advance!
Gunter
