Mechanical Engineering of Cast Aluminum SHROUD

We have a design that is currently designed from a semi-functional standpoint using fabrication techniques and need to modify the design for a sand cast solution. We want to eliminate as many parts of the existing SHROUD as possible including the base plate, We will need to design for a small access plate which will be fabricated and screwed down from the inside. Further conversations will be required obviously with the selected freelancer, so please ask questions until you are comfortable with the scope of work.
