Eric, thanks for up dating that. I haven’t had a chance to look it over but I have seen your other videos and find then very informative.
Andy, sounds to me like they were doing some kind of annealing. Aircraft aluminum is often 6061 T-6 or similar temper. It is somewhat difficult to work in this condition but once it’s annealed you can work it with a dolly and hammer. Of course there is no way to re-temper it back to it’s original state and you certainly wouldn’t want to do this to a structural part.
