I was wondering if anyone can help me make sense of this part.  I beleive I have everything correct on it except I can't figure out the Section A-A.  I attached the drawing I am making it from as well as my model.  I am aware that there are two parts on the model as it will make it easier for my machinist to make from a solid bar. I am using SolidWorks Premium 2012 SP 2.0.  Any help would be greatly appreciated.

Thanks in advance,

Chris
