How to turn a part with a shoulder at each end?

[Nelson]

Hey guys,

This topic was discussed on another forum, but I didn't see a definitive answer, so I thought I'd ask here. If you have to turn a part with a shoulder at each end, where the gap between shoulders was only about 35mm long, and the height of the flange/shoulder was about 8mm (35mm large diameter, 27mm small diameter) in mild steel, how would you set it up to accomplish it?

Thanks,

Nelson

Can you put a center hole in one end? Do all diameters need to be concentric?
