So, this is how I have my safety wire.


These are the tools I used for the test.


My first step was finding out how much torque it takes to remove the spinner. But, my torque wrench only goes to 150 ft/lbs, and it takes more than that.

Next, I used the lead hammer and loosened spinner to finger tight. Then added safety wire that had no slack in it. My goal was to find out how much torque the safety wire can hold.

I'm using .031" SS aircraft safety wire. It will break right at 35 ft/lbs. Tried it three times, had the same result each time. As Ed mentioned above, the wire broke at the same place every time; right where the wire was bent back.

So, what did I learn from this? Only that the safety wire will break at 35 ft/lbs. And, that I need to get a bigger torque wrench.
