One down, and one to go. I used the same method on this side, but it was destined to be a battle from the beginning. Even though I center punched the stud, the bit was determined to walk off center. I finally got adequate depth for the extractor bit and began the process of run it in, take it out and lube it again. Things were going smoothly till the tip of the extractor snapped off down in the hole.
I tried a center punch to shatter the extractor tip, with minimal progress. In frustration I found a hardened drill bit and tried to drill through. Of course that snapped off too.
Now I have the remains od the extractor and the bit in the hole.
I decided to walk away and research my options.
