wobbled out mirror thread

[Mikey]

I just noticed a few rides ago that my right mirror would turn out of adjustment
I would tighten it a little adjust the mirror

and it would just loosen up again and again
Anyway what could a person put on the threads to take the wobble out
Teflon tape / RTV ? just throwing it out there

that looks weird because there's usually a locking nut of some kind.

if it tightens some other way, if it's tight it shouldn't be able to wobble?

What I'm seeing is that the mount id threads could be improved by shaving down the mount top surface just a bit. 1 or 2 threads. This if done well would also create a more flat surface for the mirror to bottom onto. Those two flat surfaces need to be as parallel as can be for the best bite at each other.
The mirror stem od thread itself is quite short looking and could be wrapped with Teflon tape as well to create a tighter thread fit ?

What's the rest of the mirror look like? As mentioned, there doesn't seem to be a locking nut on it. Without that, I don't see how it would ever stay tight. Also, that side is usually a reverse thread. The lock nut usually has a line etched into it that signifies it's reverse threaded .....

Maybe what we are seeing in the partial pic is a rt thread on the end of one of those extension/adapters ?
If that MC is tapped right hand well that at least does open up more mirror options..

The mirror is on a Triumph the thread is right hand
The odd thing is when I think it's tight it will come loose and to get it tight again it will be a different position on the mount
Like a 1/16 of a turn more clock wise
It's not bottoming out
Maybe just a lock nut and Teflon tape to keep it tight?
This only started recently like the last 2 times I had it out

JB Weld that Biacha

last resort if all else fails

actually joking aside a light JB weld film might just help hold the two flats together. I would of course NOT get any on the threads. But JB would also crack and release before any metal broke if needed in the future.

Once I got time to get it of it did look like that with a locking nut to hold the mirror from turning
I took the parts to a friendly machine shop to have all the threads cleaned up
Goes on perfect PO must have

decided if he couldn't get it tight enough then might as well reef on it

hey, you previously didn't say that you had enough thread for a lock nut.. or a locknut lol..

That was an option I was thinking about
