You could still vee out the crack and weld up with nickel rod plus weld the strips to the body as well then it would be a lot better than new but the for the cost of the rod you would almost have half the price of a new press.
The cast iron in those little arbor presses is just barely above the Blume stage in refinement but with a good preheating and a little care you can even weld it with oxy fuel and old piston rings, it really takes to brazing well too.
