Thats a big chink of steel. Instead of epoxy, i would use aluminum scrap, melt it and pour it in the column. Money wise it would be even cheaper. But whatever you have at hand.
Or some special cement /+ sand+stones/, that does not crack or shrink, for industrial flooring. It has epoxy in it.

So your will drive it 1:1? What motors and screws? I have always thought it wiser such a machine to be driven 1:3 or 1:2 at least,servo or stepper. Personally i don't like directly driven screws. I prefer pulleys and short belts
