Rounding a spinner on a British Spitfire Hi, I am attempting to make a British Spitfire to the best of my ability, but I have encountered a problem. I have used a Cone Mesh to try and replicate the spinner of a British spitfire, but I cannot get the round shape that I need for it to look realistic. I will provide a picture below. 

Once I am finished with the base shape of the spinner, what would be modeling steps to making it look more detailed? Below is a picture of a British Spitfire spinner.
Here are the steps I would take to model that:

1: construct a base set of vertices from one side of the rounded top, like so:



Add a screw modifier: (make sure it is lined up to the axis for this part).



Then finally add a subidivision surface modifier to make it higher poly:



I hope that is what you are looking for. You can just adjust the vertices (or line them up to your image) to get the curve you want. When you are done, you can apply the modifiers and put it on your plane.
