I have been building the American Clock based on the book from Steven G Conover. This is my first build. I have no experience in clock repair, but I have broken one clock and fixed three so far. It has been a learning experience and I am close to finished. It runs very good and is easy to adjust and is keeping very good time so far. My problem is with the click. It does wind if you are carful, but as it get to the end of the wind the click spring comes off with the resulting unwinding. I did not use brass wire for the spring as in the book, but used steel spring wire. The photo shows how it is made. So any thoughts about what is wrong.
