Hello everyone, I will be soon making my own power hammer. I would like to make a bow spring linkage as seen in the pictures below. From what I have seen and read the springs need to be bent far more than what is commonly available in the form of trailer springs. My Question: How would you bend a trailer spring into a near 'U' shape? Can it be done safely? Please let me know what you guys think. My idea was, worst come to worst, I will just bend them in the forge while hot, and leave them unhardened.
