Thread: Oh bugger....

At least you managed to drill the middle of it!
The amount of stuff we get to fix after someone has already drilled miles off center and or broken the drill or tap off in it:rolleyes:

A good trick that works 90 percent of The time is to weld a decent size nut onto the stud.
Doesn't matter if it is below flush just get in there with the tig and build it up till you can sit the nut over the weld and weld it on.
All the heat goin into the stud makes it expand but it can't go anywhere so when it cools it shrinks and should undo relatively easily. Just make sure you let it cool before trying.
