MS51990 lock ring serrations

[Mohammad041990]

Greetings everyone

I have a worn 7050 Aluminum Bulkhead structure (MS51990 lock ring outer serrations are completely worn out) a new lock ring cannot be installed.

Any thoughts about a good practice for producing new lock ring outer serrations in the structure ?!

I was dealing with Beam Seal fittings that had this locking feature. Here's a series of videos on how to cut this recess using different types of tools.
