Hello people, pardon my stupidity. I did something not too bright, I tried removing a rivet nut from my aluminum frame bike by twisting it out. What I got was a mushroomed hole that I had to gently hammer back into shape, while doing so I apparently created a short crack in the frame next to the hole.
Before I install another rivet nut and take this bike out for some riding, is this bike safe? Can I expect this crack to expand and propagate or am I worried about something that probably won't happen? Picture should be attached. Thank you.
