Actually if the entire point of the whole new element (isotope, isotope, damn it!) plot was that Stark Sr didn't have the technology to make it . . . Dude, I know the 50s were way behind technology levels these days but this guy, by Tony's own dialog, died in the late 80s. I am pretty sure that high technology in the 80s, accelerator/collider-wise, would be at least as capable as any kit Tony could physically fit into his basement.

Conclusion - Tony? Fury's lying, your dad really is a douche.
