# Roller Milling Spent some time working this out on the whiteboard today, and threw together some rhino sketches. ![wb](/images/wb-01.jpg) I'm going for simple, strong-enough, and easy to build. Using rollers and pulleys, or, just as easily, rack and pinion or leadscrew-type actuation. Not trying to be prescriptive or suggest that anything is 'universal'. Next up, getting into fusion to get through the details, then fabbing one axis... designing a simple 3axis machine, and fabbing that.
