Since there is some interest in learning some of the basics about using machine tools, I'm gonna post a few more pictures to explain how to use a Rotary Table for basic stuff. Enjoy! Edit: Everyone needs to realize that all machining is done by locating a part directly under the center of the spindle of the machine, and then moving in relation to that established centerline. This is one of those times when I'm saying something that is not always true, but for the purpose of understanding basic machining accept it as true for learning purposes. Hope that peaks some folks interest and shows how simple some machining can be.
