In my previous thread on this subject I mentioned I had chosen the wrong scale for the Z-axis of my FB-2 mill. I contacted Alan Ward at Machine-DRO, and he was fantastically helpful; I can strongly recommend their service.
I also mentioned to Alan that I was uncertain about fitting DRO to my Super 7 because of the difficulty of finding a location for the cross-slide scale. Alan was kind enough to send me a copy of the text of an article they have written on fitting DRO to the Myford 7-series lathes, which was very useful, though it will probably be even more clear when I see the photos on publication. Incidentally, Alan told me the article is to be published in MEW issue 126; those interested may want to keep an eye open for it, or even buy a copy if they are not subscribers (hard though that is to imagine).
