[QUOTE="Trickymissfit, post: 1159522, member: 25383"] take your lead screws and nuts to Lead Screw International in Travers City. Excellent work. They did all my ball screw work, and some oddball acmes. The absolute best bed grind I've seen (and I've had many a bed ground) is from Viking Engineering in Hammond Indiana (very close to Chicago). They'll come and get the parts if it's fairly close (say 200 miles). Had them do two or three Bridgeports for me and when I checked their grind on the surface plate, I saw .0002" compound error. They have a grinder up there that will do .0003" in 20 feet!!!!!! I know for sure it will do .0002" in twelve feet, as I had them build me a bunch of ways for the X axis of Devleig jig mills. Tail stocks are often messed up by folks that think they needed repair. When what they really needed was a proper bed alignment. If the bed is not dead strait, it will never cut strait. The V and the flat are somewhat of a black art, and few folks actually understand the proper ratios between the two. If the flat is too high, one side of the V will wear to fast due to the way it loads. If it's too low, the otherside wears too fast. Pray it's always too high as that's a bunch easier than scraping the v lower. gary [/QUOTE]
