that looks more like a shaft lathe and pipe lathe for a ship yard, the only reason i say that is i worked for otis ship yard in la for a while as a welder and they had one that could cut some big shafts and thread 100ft lengths of pipe for conduet and as a teenager i worked at a milling plant that made telephone poles the machine that does that is sizer and debarker the tree goes inside it it debarks it then planes it down to the spec, either way its a huge lathe:thinking:
