Well, I just got the shape I wanted but not from the previous method.

I was able to select the circle at the bottom and then the other horizontal curves and sweep them using the vertical profile curves as rails. There is some weirdness at the top where the sweep ends but the mold maker can sand that out.

While it looks like this project will work with sweeps I'm sure I'll need to use networks in the future.

thanks again fo your time helping me.
