I am increasingly pleased with my ability to make stuff very accurately. I received an order for some ScopeRollers for the Celestron CI-700 tripod a few days ago. Much of the work on machining a part is the setup: putting the cutting tool in place; installing the drill chuck in the tailstock; positioning the tailstock; zeroing the handwheels. Therefore, if you are going to make three parts, making nine identical parts isn't even twice the work. I wasn't putting any extraordinary effort into this, but because I have become fairly adept at this, I turned out nine perfectly squared cylinders that ranged from 3.599" to 3.602" in length; that's a .08% variance in length.
