Right next to the Jesus Nut.............
Yep :D
I distinctly remember the first time I heard of “The Jesus Nut”...I was on the USS JFK watching a guy with grease all over him working on the rotor of a Sea King. I mentioned to one of the guys below him that I had some misgivings about riding in a machine with such a complicated looking thing whirring above me, and and I asked what he was doing.
He said something like “Looking at the Jesus Nut”. I thought he was making a sacrilegious comment about the genitals of Christ, and said “Wha..tttt?”
When he saw the look on my face, and before I could ask, he said something like “It’s the big thing on top that holds everything in place, and if something goes wrong with it, you are going to say hello to Jesus.”
Now THAT is a piece of hardware every 19 year old mechanic will remember!
