Tight bottom bracket, slipped tool damaged teeth :(
For whatever reason, I felt the need to take the bottom bracket out of my 1998 GT LTS last night. I applied plenty of penetrating oil, but I don't know how much of a difference it made. The drive side was tight, but I managed to get it out, regrease the threads, and put it back it. Non-drive was also tight, very tight, and I managed to screw everything up. I have it out maybe 4 thread lengths, but my bottom bracket tool slipped on me (user error most likely) and the tool let loose with a destructive grind to the teeth on the bottom bracket.
Any ideas on how I can get enough leverage to remove a tight bottom bracket without using the standard methods?
EDIT: Just thought to put the exposed threads in a vise grip. Hopefully I can get enough grip that way and it doesn't matter if I damage the threads (getting a new cup anyways). Kind of an "oh duh" moment, but writing out my problem helped out quite a bit. Just in case, any other tips?

If it isn't completely stripped you may be able to extract it by just bolting in the tool - depending on what bb it is. I'm guessing it's an octalink/shimanon splined tool you're using?

Don't take any chances. Always bolt the tool to the BB spindle when removing the BB. Save your knuckles.
