One of the projects dad worked on when he was in CPC Advanced Manufacturing Engineering was the second generation Fiero frame (aka "P2" chassis).

It was to be a space frame construction, and one of the options was a welded tube build - or - tubes with cast connectors at the nodes. As a result he traveled to Schwinn, Hitchner Casting (they make Crane rocker arms, among other recognizable castings) and Mr Gasket to review their various manufacturing processes.

(The ended up going with a combination of stamped aluminum and hydroformed aluminum tube, and built and tested a couple parts, before the program was canceled).
