How do you turn the OD of a part with no other features to hold on to.

The video provides a practical, step-by-step solution to a common machining problem, offering a clear demonstration of a clever technique that is valuable to machinists and metalworkers.

The video demonstrates a method for machining the outer diameter (OD) of a part that lacks features for conventional gripping. It involves creating a custom stub arbor that fits snugly into the part's internal splines, allowing it to be securely held and machined on a lathe.
