Well howdy!
I've been gone quite a while and hadn't looked this thing up for quite some time.
Glad to see some positive replies to my questions about the safety of the repair. Pretty much all of what you are saying is about what I figured before I started this project. I always figured that yes, bending metal work hardens it and if you do it repeatedly it will break but this little bit of movement didn't seem like it would be an issue.

Thanks for the tip. I'll check them out. Always willing to learn something new.
