Tell us about yourself!
Bingo! Someone finally got it. I have used this many times in my too long career as a mechanic. First thing I try is a very small sharp square ended punch to make a notch in the outermost part of the fastener (stud, screw etc.). Then I tap the screw cc wise. This works more than half the time. The nut welded to the stud or ? is my final go to fix - it almost always works. Other thoughts are that an easy out is not easy and almost never works - out. Maybe 1 in 30 times. Finally, although I'm not a nail bender, the very few times I've had to remove a screw in wood I can always chisel out enough wood to get a sharp new pair of vice grips on it. Then all you need is some Spackle which all good nail benders carry on their hips.
Pretty hard to put an old 235 Chevy motor in a drill press to get an exhaust stud out. My point is a drill press is almost never possible to use. The welding method though is a good one but a nut works better.
I built a simple 9V led light with a momentary on switch.
