Soo I broke one of the bolts that keeps my gas tank straps on. There was a fair chunk still sticking out of the metal so I tried some vice grips with WD40 and that failed miserably. A big part of the problem is that I cannot get to the top of the bolt (it goes in upside down) as its in its own sealed off part of the frame so I can't really get WD40 or any kind of penetrating fluid for that matter to drizzle down through the cracks. So then I tried drilling it out, and I've gotten it pretty hollow for the most part. I didn't drill all the way through to make a hole on the other end though, if that changes anything. Once it was hollow enough I tried wrechning at it with locking pliers and it collapsed the exposed part of the shaft as expected but I just couldn't twist it out. I then proceeded to rip off all the excess metal at the top, and the rest of the bolt is still in the frame (save for maybe 2mm). Can anyone offer ideas? I'm ready to take the drill to my skull at this point.
