The cheapest way to make your own backlash free nut is to modify the nut. You cut the nut in half so to speak and install a spring in between then you have to contain the 2 nuts. Generally I make my nuts from scratch and counterbore each side in the lathe then I install 3 pins around the nut just outside the spring diameter and peen the ends of the nut. I've found this method pretty good at elminating backlash but nuthing beats a good quality ball screw.

Just a Thought
