Assembling the Geekcreit® 8x8x8 LED Cube 3D Light Square Blue LED Electronic DIY Kit
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.
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.
I built a simple 9V led light with a momentary on switch.
