1.) Cool idea for a pocket watch! 2.) If you have your original spline model, go back to it and increase the surface fidelity in the spline model to be as high as you want. What this will do is increase the number of subdivisions the spline model will hack into your cross section and make it much more smooth. The problem you're seeing is very common in spline modeling using the default fidelity. 3.) Then convert the much higher fidelity model to a vertex and add your thickness. You could have modeled this as a torus in the spline modeler as well (just another idea). You might have also tried using a thin ring and changing the sweep path width between two points and using the pipeline extrusion (not to sure about that one though). I think the method you chose for this is just fine. You should be able to get the result you need with no problem. -Kix
