Removing broken bolt video: What do you guys think?

[bonneyman]

I came across this video - guy seems knowledgeable as heck with what he's doing. And I get most of it.

But I'm no expert. It's a 36 minute video, but, I'm wondering what you guys think who have alot more experience doing this kind of thing.

After grinding it down flush, I would have welded a large nut (rather than a bolt) to the stud. The stud's long length flexes too much under heavy torque load. Also, once the heat dissipated the stud got stuck again -- better to do several heatings and remove the stud slowly rather than try to forward/reverse the thing with one heating cycle.

A good lubricant would probably also help in the removal.

What kind of a hack does this guy think he is? Just grind it down and leave it and let the remaining bolts do the job.

Its a thru bolt, just drill it out and use a long bolt and nut.

 1/4in looks about right grade2 would be best. Then beat the threads over if there are any sticking out past the nut. you don't need a lock washer that way.
