There are many types and styles of click springs for our mechanical clocks. This particular one is for a Gustav Becker P-42 time and strike wall clock movement. Notice the previous repair on the left and the right one was pretty rough, though they both functioned, I found it enjoyable to remake both pieces to look as original as possible.
I know I could have sourced a spring from a supplier but I found it a great learning experience to fabricate one myself, not only that but some styles you cannot find the style needed. Here is the original that is in rough shape. I used this one as a template
Final filing, using the top of the vise as a straight edge works well.
Finding where the screw hole goes I drilled those out. Mounted in the vise I used a very careful tapping with a hammer and large punch, the bend does not have to be a sharp angle but it does have to be in the right spot. What I mean is when it is sitting on the plate the spring will have a bit of clearance so it doesnt rub the plate.
Before moving forward I checked the clearance of the spring and the tab and hole alignment.
Using a round nose pliers I bent the shape to be similar to the original. I say similar because the original was tweaked a bit out of shape.
A quick test of function before hardening.
