On the lower half of the 'horseshoe' is the base plate, wich holds the light switch and some additional ornamentations. I only managed to get both in place with a friend of mine and a lot of clamps. Once the outer one was solderd on and you would start with the inner one, the outer one would come of again. The outer rim was easy, the inner one not. Copper is very heat conductive and so it takes a long time for the part you want to solder to reach the right temperature and the heat spreads over the whole piece. Those ornamentations are basically thin brass rods, bend by hand and then glued on with an industrial body glue. The third 'horseshoe' is the final version, with the outer and inner rim soldered onto it, all the holes in place and the additional brass ornamentations attached to it. Why aluminum? Its softer and easier to work with than steel, but also cheaper than copper. Only missing minor things like some of the holes. The second sample i made, was out of aluminum and had the right size and shape. The first one is made out of steel and neither had the the right size or shape. (I often marked changes on the desin or future places for holes ect. All of them are made with an CNC machine i had access to. Here are the steps (left to right) from the first try, made out of steel, to the last one made out of copper. The 'horseshoe' part took some time and tries to finish.
