Hi Peter

    If I were to do what you have mentioned, I would be inclined to take
    the wax sphere and split in two, hollow out the inside, and cast it
    in 2 pieces. You don't have to have a huge sprue for the wax, but you
    might want to put on a couple of return sprues from the top of the
    spheres back to near the base of the flask base. After you cast the
    pieces, finish them, lap the sides that match up, and solder them
    together. Just a thought. 

Good Luck
Dave
