You done well, it looks like an odd thread to me. I also thought the steel would have to be some sort of tool steel as it looks a tough job to pull that rota. This forum always proves to be fantastic.Yep. Threaded and pointed it on the lathe, then cut a 1 1/16" hex on the back with the mill. Worked like a charm. Props to Paul for posting that CAD drawing above.
