When I worked in the shipyard we cut the gun mounts with pretty conventional home made boring bars made out of H beams and other stuff with a star wheel on the outside that hit a stob welded to the wall to increment the tool out. It was turned by a gear motor attached to the ceiling. Took about 9 hours to make a pass. The shaft alley was bored with a giant boring bar that turned out chips as big as your finger. Of course all of this had to be done after all the welding was done.
