Step 2: Step 2: Create the Crank
For my Vito-matic, I made the crank out of cardstock paper. Take a sheet of cardstock paper. With a ruler, measure off four equally spaced lines approximately a half an inch apart. When folded to form a triangle, this shaft should fit snugly over the CD containers shaft . Trim off excess paper. Fold the paper to form a triangle as shown. The shaft of the crank should be slightly longer than the depth of the CD container. Mark this length with pencil or marker. Cut as illustrated to form a "Z" shape for making the crank. Use the scrap of paper, fold and insert to strengthen the joints of the crank as shown. Cut a triangle shape hole in the center of the paper wheel and insert the shaft. Tape or glue this shaft securely to the wheel.
