Perhaps the rigidity issue is in the part, not the machine? The lathe
sounds massive, but he's turning a part to 25mm which isn't that
massive.

With "only" 7" of overhang, a 1" bar wouldn't be too rigid to deflect.

He never mentioned whether or not it was supported on the outboard end, or
in a steady.
