This had some good ideas.
Here's another one, more difficult in my estimation.
In years of tool repairs I've used some similar techniques and each job is a different challenge. The rusted in, blind hole stud is probably the worst.
Having a full machine shop really helps and patience is your friend. Tell yourself that at 10:00 PM the eve of race day when the bolt your are tightening suddenly becomes easier to turn.
If you go to the first video he links some videos to other good techniques.
