I was just wondering if there was a tool to put threading on my metal control rod.

This is my procedure now: I cut the metal rod to size, and only one end of the rod has the threading. I thread on the plastic clip that clips on to the control horn on the end that has the threading. On the other end, I make an "L" bend that clip on a different type of clip that keeps the rod connected to the servo horn. I really like using these metal clips that are made for pull-pull systems since they thread on easier and in turn makes it easier to adjust the length of extension my conrol rod has. The only problem is, I can't put it on the servo end because of the lack of threading. I hate making those "L" bends and adding that clip. It's really not engineered too well and sometimes the connection area hits the servo causing immobility/battery drain.

I hope all this made sense. I wish I knew all the proper terms for all the parts. I'm sure that would make it much easier for you pros to understand.
