Hi Steve,
I milled that one with a Brute. I orignally designed my
mills so people would have a machine to learn on. Someone asked
me if I could design a mill that would do circuit boards. My first
machines would mill, but the traces were not that good. It wasn't the
threaded rod. It was my drive nut! The wider the drive nut the less
backlash. I now use 1/2" wide Delrin tapped with a good 1/4-20 tap.
