Soup Can Savonius

Step 4 Layout

Time to trace the soup cans again. This might get a little tricky. Lines on top and bottom of one section should be mirror images of each other. Make sure that in the middle, the soup cans are catching wind in the same direction, just rotated 90 degrees from each other. Its easiest to start by tracing the bottom, then placing the middle on top of the soup cans so that you get started on that tracing right. If you can wrap your head around it without physically doing it thats great. I traced inside and out of can. I only used one can for it all.
