The EAA states that building your own airplane is educational. Well I'll
say!! I spent the day down in my shop working on the swedging problem.
I am pretty sure I have the answer to what needs to be done. As the alloy
is 5052 and .090" in thickness, it seems to hve good workability.

One of the Emeraude builders of my acquaintance faced a similar problem. He
needed to construct a "pass-through" in the center of his tank to allow the
carburetor cables to penetrate the aluminum. In his case, he swaged matching
holes in the front and back of the tank and then welded a piece of tubing
through and through. He built a swage similar to a chassis punch and it
worked rather well.
