Make all sections equal width, repeating
sections as required for desired total width
Note: Make all the rings equal width, repeating rings as required for desired total diameter.
Where a choice exists, use the largest number of rings to achieve the desired diameter.
Rings are shown in different colours for clarity, but are electrically connected where they meet.
