Steve,
Silicone bronze or aluminum bronze Tig will work and turn out to be a great repair.
completely grind out the crack and profile into a deep V larger the better, do this with a steel rotary burr bit and not a disc grinder
Cut a slug on the lathe the same size diameter of the mill column, install the head on the slug and firmly apply pull straps to squeeze the head on the slug-pin. thoroughly clean the ground out V to be welded again and now put this in an oven and heat to about 400-500.
bring it out on the table and keep it wrapped in welding blankets tig it up it up, if you cant do it take it back to the welder and tell him how to do it.
Its not hard to weld CI.
Its a shame because if you don't repair this one if you find a second hand mill you're going to pay through the nose for it, i would not think you could buy a new old stock one.
Hope this helps
Anthony.
