From what I can see in the pictures you have several components that need to be made separate. The first are the anchor brackets. I believe you have these made already. The second is the threaded rod. I think you can make this by using a threaded brass screw and then making the end from round stock. Solder these two together and add a nut at the bottom and you'll have the second part. The third part is the ends for the landing/flying wires. These can be crimped and soldered to some narrow flat stock. That'll give the appearence of the full size. Forthly you might want to make the "keeper" brackets that hold the adjustment nut in place. It's not necessary but it'll look good.
