The approved redesign contains qualities suggested by team 09F and was modified by CJ Winter to fit the existing 234SA rotary radial attachment with minimal modification of existing parts. The major additions can be seen in figure 9, below. Major additions include the closing of one side of the roller pin holes since a press fit is used and there is no forseen desire to remove the roller pin; the addition of material in the sprocket pocket; the addition of a radius near the sliding surfaces and the enlarging of existing radii in the sprocket pocket; the extension and widening of the outer wall material where the highest tensile stresses occur during loading.
