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.
“Nine-tenths of tactics are certain, and taught in books: but the irrational tenth is like the kingfisher flashing across the pool, and that is the test of generals. It can only be ensured by instinct, sharpened by thought practicing the stroke so often that at the crisis it is as natural as a reflex.” ~ T. E. Lawrence
