Hi Bryan, ok now when I re-read your post I think I understand that the drawing is a little wonky because you don't have the original drawing just some things written on the object?

But as long as the cone and sphere are supposed to be tangent where they touch it's enough to have cone angle, cone bottom radius and sphere radius. The station measurements aren't needed. However if it's not meant to be tangent then those slab thicknesses would probably come into play.

Greatly appreciates all the help. Lots of options. Of all the models I'll be working with this was likely the most complex. The rest are just cylinders attached to each other.

last night I generated a Calendar and Chamfered it. the generated a sphere and, and copied it then merged one of them.

Then did the Boolean Dif operation to remove the upper part, then dropped the copied sphere onto it.

the Dim's are for a 1/24th object, but the final object will be 1/144th, so the issues will be all but invisible.

This is a common object to multiple models.
