    Precision, precision, precision. 

    There must be alignment pins for the halves. The holes need to
    ground to a finish not just drilled. The holes in the bottom plate
    have to be relieved just back from the upper cutting edge. The
    punches need to have the cutting surface at a slight angle rather
    than straight across the punch. 

    Study a book on tool and die making first! The thickness of the
    metal to be cut is not really a problem here, it is the overall
    quality of the piece. Unless the precision fit is there, the metal
    will fold over in to the hole instead of shear off. Just like when
    you cut a sheet with dull shears. 

    Interesting idea. Unless the" engineer" is a practicing machinist, I
    would be very leery of this project and his input. If he has not
    pointed out what I just did, he doesn't have a clue. Read a tool and
    making book first!
