    Clearly, yes some people have strong opinions.



    I am using Delrin anti backlash nuts on my converted Chinese mill but then it is only a toy for learning and occasional use in model engineering. I have 1 thou backlash on both X and Y axes and it gives very little friction at that setting.
    Delrin will have reduced friction But I found that it just acted as a damper and masked the backlash. measuring low backlash only under a no-load condition. Once the load is applied it compresses until the the other edge of the screw is in contact( ie play in the screw/nut). The amount of compression is dependant on the load so you end up with varying amounts of error on the work piece.
