#12 The ONLY one that I knew! Probably has something to do with my age - 73yo!
This is a metal disk that fell off a truck in front of my building. No one ever came back for it so I decided to take it. It’s about 2.5′ across and 2″ thick. Back side is perfectly flat, looks machined. My guess at weight is 110lbs.
A: This would be sent for precision CNC at a specialty shop to cut notches to attach blades before stacking. Doesn’t need to be titanium. This is why they’re called wheels in in the ground-based turbine world.
