Poor Little Cone Style

Well, the exact same rotational forces make cones work that make clutches work. They both occupy the same space and perform the same work. The same force that locks clutches together locks cones against the case. Once power is applied preload springs have little to do with it. We simply disagree. It doesn't matter to me that you run a business and do it everyday. I'm not afraid to argue when I am not wrong. I am sorry that your pride won't let admit that you are.
