    However as you have done a super job of fitting a DRO you have made backlash irrelevant and given your lathe a better than new accuracy.
    The reason I did not fit DRO to my lathe is that I do a lot of milling with it and so backlash is something I needed to reduce is much as possible.
    Thanks for the comment. The dro works very well and I can hit my mark pretty much all the time now.
