Bruce, thank you.
Actually, no sphere needed.
I started off that leg with a 2D DWG file that was given. I copied the square sections off to one side.

Deleted half the leg profile and the square sections.

Push/Pull the square sections. Extend the profile for the turned portion to create the pommel. Add a path for Follow Me.

Run Follow Me.

Move the square section into place. Run Intersect.

Delete the waste.

To reduce the turned piece's file size as Eric mentioned, I rotated the 24 segment circular path for Follw Me 7.5° and then cut the circle in quarters cutting at the midpoint of edge segments rather than at the vertices. After running Follow Me on the turned parts, their edges were hidden. These were made into components and copied about the center. When all the components are placed together, the seam lines don't show as they would if the cut had been made along the vertices instead.
