link design. "You have a lever which is in contact with a snail or a cam in the center on the minute wheel. And it takes the power, draws it over the hour, and once per hour, it falls and strikes a star in the center, pushing it one step forward and moving the jumping disc. So I had an idea. Why
link don't we take this lever, and instead of hitting the star we can strike a sound spring to make this nice gong effect?"
