We cast and machined some aluminum hubs for our wheels one year, if I recall correctly... or maybe it was the ends for an intake roller.
We didn't make a big deal of it.... we had the facilities and it was the quickest/easiest way to get the part we needed.
Mind you, that was "back in the day" before Andy Mark had a solution for everything.

Edit: Oooh! Does that qualify us for "obscure team" status, or just "crazy stuff" status?
