Once you start using a mill with a 3 axis DRO and a good fixtures its hard to go back to anything else. It would give you track pin holes dead square and spaced with in .002 easily and all the other parts that need to be the same come out that way. Doing it to this level is what I am used to with the work I do so it reflects in my hobbies. I have a Bridgeport and a 13X36 lathe at home. Thats why I have an interest.
