The inchoate state of Pilot’s elevator, despite its age, was due in small part to the length of time Pilot had taken to form its roller-bearings.
Anyone who knows anything about elevators knows that without roller-bearings, they’re not going anywhere. For whatever reason Pilot had to forge Elevator’s roller-bearings himself. Elevator’s roller bearings either were never there, or disappeared.
Now if you were asked to forge some bearings, unless you are a metal worker, you might not know where to start. In fact, Pilot was not a metal worker and he did not know for a very long time the first thing to do was address his own Hinge Axle.
