exhaust manifold broken stud removal fail

In this video I show how not to remove broken studs on small block chevy exhaust manifolds. I use erwin bolt extractors which was a fail because it just broke the ends of the studs. Next, I try to drill out the studs and extract them, and that was another fail. Then I do something that I do not recommend to anyone, I drill the hole out for the same size tap as the original bolt. I some how get lucky and cut the same original threads. I do not recommend doing this job that way, but I got lucky and it worked.
