Next to make a clamping fixture. My mill table is way too small to clamp over the shell by resting it in a slot, and I probably couldn't lift a vee-block large enough for the 12" diameter piece. We settle on clamping a large block of steel, previously used as a vice jaw to bend the tumbing shaft, to the table and indicate it square.
