Time for action — making the hub
Making the hub is easy. It's a cylinder:
Press Numpad 7 to get the Top view.
Press the Tab key to get into Object Mode.
Press A to deselect all objects.
Press Shift+A and create a cylinder from the Mesh menu.
In the Add Cylinder subpanel in the lower half of Tool Shelf, set the number of Vertices to 18.
Press S, 0.25, and then Enter.
Press M, 2, and Enter to move the hub to Layer 2.
What just happened?
That was easy. You put the hub in Layer 2 so that it won't interfere with your work of making the spokes for the wheel. You will start by making a circle to control the placement of the spokes of the ship's wheel.
