Well, the fact is once that spring is broken (and the ones I saw were broken at the point where the springiness was most needed) nothing you can do will restore that original temper. As I said the ones I fixed were stiffer but they did work. It is all about heat...brazing takes less heat than welding although if you could weld very hot and quick (quick as a rattlesnake) you might have a slim chance. But you'd be welding a 3/64" piece of spring wire so you'd have to get good penetration to make it stay together. Yes, a ferrule with set screws would work if you sacrificed the spring and cut it so that you had two straight pieces and then welded two ferrules together in the same angle you needed. And with the ferrule you still lose the spring from that bend. It would be gone for good. After I did this, the seat worked. It was just less springy than when new. It no longer had spring in the bend but on either side there was flex. As I said, hopefully somebody will have done this another way in the past. Broken spring steel is just not easy to repair.
