A little earlier, someone asked about Kirkham testing. We do testing all the time--usually to destruction 
Here was one of my dumber ideas. We were going to make the threads on the hub out of aluminum to save weight on the hub.  (It is a LONG story, for another thread)
Anyway, no one thought it would hold and so we set up a test. I lathed an aluminum hub and screwed a wing-nut on it. We then tried to break it off in the press. Notice the I beams are bending
