Leave the drills put up for awhile. Take a standard electric soldering iron, let it get good & hot and then hold it on the broke leg (or hole it's broke off in) until you see a wisp of smoke. This is the heat liquefying the loctite and should come in the first three minutes or so. Give it another good minute and get to work on it with a dental pick or similar instrument. If you feel it move, you are getting there. I'd warm it up again and put a drop of oil in the hole to free it up some.
I'm inclined to think if a man hasn't gotten his point across in 4912 attempts, 4913 probably isn't going to do it.
