This is probably one of those old tricks that everyone but me knows, but I thought I'd share it..
I was driving screws and the head broke off of one... I reached in the drawer for the vice grips and then decided to try taking the driver bit out of the drill and tightening the chuck over the broken screw..
Sure as hell, when I reversed the drill, the screw backed out smoothly...
Why didn't some one tell me about that 40 years ago? *sigh*
Sort of like the tip I read here in the wRECk a few years ago about tapping a screw hole in oak with a steel screw before using the brass ones.... lots of things that some folks "assume" that everyone knows.. Mac
