Get ready, here comes your "it's so stupid it doesn't deserve to work, but it does" of the day. The piece broke clean, so I was able to clean everything really well and just set it in place like a puzzle piece. After grinding down on a spare battery terminal to eliminate the inner bevel and make it thin enough not to interfere with the spider mounting height, this gives a clamping force all the way around the boss without the worry of losing pieces of epoxy or JB Weld in the engine over time. The stud has a very good grip and is attached with red Loctite. I'm pretty confident that if that stud is subjected to enough force to pull this apart, I have another problem big enough that it won't matter much anyway.
Brilliant!
i would have never thought of using that to make a repair but it should work others may disagree. If it where me I would make sure to do something with that nut so that it doesn't back off and end up somewhere it shouldn't. Saying that might just be me overthinking though.
Your thought process is on the money. Here's how we make that nut stay in place forever:
Step #1: Buy a pre-drilled nut like this:
You must be registered for see images attach
Step #2: After tightening, safety wire drilled nut to immovable object like so:
You must be registered for see images attach
NOTE: See attached safety-wired oil pump cover bolts for an idea of what it
should look like when done.
By securing your cast iron reinforcement with a little bit of safety wire,
you will have an aerospace quality permanent lock on top of your
brass bandaid.
For what it's worth, I have *never* been let down by a quality safety-wiring,
and that includes numerous sets of eyes inspecting it after the fact, often
for weeks/months post repair. (Remember, I have to sign off/take credit for
all my on-aircraft work, and this documentation is a forever thing.)
As a matter of fact, if this was going into one of my daughter's vehicles,
I wouldn't hesitate to do this. (That's my highest rating. :0)
Whaddaya think?
