I inspected in an aerospace machining plant specializing in large aluminium, hard steel and titanium parts for aircraft. Wing spars and ribs, landing gear trunnions, flap tracks etc. Almost a hundred union and another fifty non-workers

in mismanagement. The only lathe we had was a manual metal lathe (16 x 40) that maintenance used for repairs. Everything was CNC mills. Forgings and plate came in at a ton or two and went out as finished parts at 100 to 200 pounds. The rest chips. Nothing we had was as big as that puppy of yours though. Okay maybe some egos.
