How Bad Am I Screwed? :(

Yeah, I was thinking using grease or something to catch the burrs, and I suppose aluminum is soft enough against steal bearings. It's a gamble I guess, idk, I might just throw on a switch until I can do it 100% right, lol

I wouldn't screw around with it, it's not worth the trouble. Do it once and do it right. Heli-coil is the best way to go here, if you don't feel comfortable doing it, find someone who can help you.
