Blending different size radii uniformly...I'm Lost!!

I am trying to make a solid model and I am having difficulty with the different size radii and blending them into another shape.  I was wondering if someone can take a look at the attached drawing and look at my model and help me with the blending of the radii around Section B-B.  Is what I did so far correct?  Any help would be greatly appreciated!!

Thanks,

Chris
