Unless you made that part out of spring steel, it probably won't work for long - it will wear out on the edge. However, now that you know what it takes to make it work, you can look around for a piece of spring steel. If you look at the one from the other thread, re-posted above, you can see that it usually involves a thin piece of spring steel. The front edge of the spring steel is kept square, with good edges.
