I am considering making an anti backlash nut for my HF micro mill. I would like to use the stock leadscrews until they are worn out, then i will look at ballscrews.
The current nuts on there are some type of iron, which i would expect has a lot of friction.
Using the method as shown here:

I would liek to make my own tap and produce a type of anti backlash nut. But what is the ideal material for this? Is it delrin, or is delrin too weak? I have never used it before
