A very simple yet effective way to make anti backlash nuts.

I needed some anti backlash nuts for my CNC. Ballscrews were too expensive at the time, but I found a way to eliminate backlash with this method. It works by moulding the delrin nut around the lead screw. This creates a slight interference fit and there is just no space left for any backlash. These nuts have been on my CNC for 5 years now without noticeable wear. If that happens, I can just remelt them. A very cheap yet effective method. The delrin slides very well on steel. I lubricate with grease.
