How do you support a long workpiece in a lathe?

To support a long workpiece in a lathe, you can use a tailstock to provide additional stability at the free end. This prevents the workpiece from sagging or vibrating during machining. It's also essential to ensure that the workpiece is properly centered and securely clamped in the chuck or between centers to maintain accuracy and safety while turning. Additionally, using a steady rest can further enhance support for longer lengths.
