Seriously Tight Set Screws!
I'm trying to take apart a frame I bought and a few of the the alum. set screws are incredibly tight. I have soaked them in penetrating oil and still, they won't budge. I have cranked on it with a socket wrench/ hex driver combo and finally tried an easy out. No luck. I guess the next step is drilling it out, but at that point, I've lost the fitting, right? These things must have been set with a pneumatic driver!
Any ideas out there?
