Hey everybody, first post so if this has been asked here somewhere else I apologize but I searched and didn't see anything on this yet. So here's what I'm looking at. I'm making an axle/wheel stud for a linear carriage application. Start with a 1 1/4 round steel bar, approx. 5 in. long. Turn one side to 7/8, the other to 3/4, leaving 7/8 in the middle at the stock diameter. Now, part of that 1.25 diameter has flats machined on each side, about half the length. My question is how do I rotate the part exactly 180 deg. to machine the 2nd flat?
