This was the first time I tried turning on the 1100. I have to make a quantity of stud bolts, 1/2x20 L.H., 1.725" long. One segment is 1.000" long followed by a 0.625" shoulder that is followed by a 0.500" segment. I clamped a 1/2" shank tool holder with a carbide insert. I turned 5/8" 4140 to the appropriate dimensions running at S4000, F20. Flooding with Mobil 766. It was a cakewalk. Next weekend I'll be turning the LH threads on each end using a 1/4 carbide thread mil. Never done thread milling before, so it should be interesting. I'll practice on some cut-offs first.
